Institute for Soft Matter

General Overview
linie570

The Institute "Weiche Materie" was founded in jan. 2000. The main focus of the Institute is to understand macroscopic properties and microstructural order of colloidal systems, under equilibrium- and non-equilibrium conditions, on a microscopic level. To make progress in this area it is necessary to be able to synthesize model colloidal systems, where monodispersity of the desirable interaction potential and shape is one of the main goals. The properties of these model systems should be tuned in such a way that it exhibits the phenomena that one wishes to study.

 

The research in the Institute is done within "projects", which will be described below:

Non-equilibrium Phenomena 

The subjects under investigation in this project are :

  • Shear-banding and Rheology of "hairy Colloids" and Suspensions of rod-like Particles (P. Lettinga)

    Shear-banding is a hydrodynamic instability in systems under flow that occurs whenever the stress decreases with increasing shear-rate, or the stress is a multivalued function of the shear-rate. The stationary state is now a state where regions of different microstructure and sometimes different shear-rates “coexist”.  The kinetics of the shear-banding instability and the possible stationary states that can occur are studied for two kinds of systems : "hairy colloids" (colloidal spheres coated with long polymer chains) and rigid rod-like particles. A system of hairy colloids where shear-banding has been observed will be investigated in cooperation with Dr. J. Vermant (University of Leuven). Another, well-defined hairy colloid has been developed in the Institut for Neutron Scattering (see the next theme). So far, our investigations are focused on the shear-induced polymer brush defoprmation at lower concentrations. Simulations on hairy colloids in shear flow will be performed in the Insitute Theory II. We recently observed a very clear shear-banding transition in suspensions of fd-virus (a semi-flexible colloid). By adding free polymer, the rate of the transition can be tuned, so that kinetic studies will be feasible in these systems. At this moment we are determining, by rheology and light scattering, the full non-equilibirum phase diagram of these kind of systems (where the shear-rate is on of the control variables). The shear-banding transition lines will be located as well. There is an ongoing collaboration with prof. W. Briels (University of Twente) on the theory of the shear-banding transition in systems of rigid rods.

  • Shear induced Polymer Brush Deformation (S. Rathgeber)

    Colloidal micellar particles of PEO-PEP diblock copolymers with a small core in comparison to the length of the amphiphilic part of the polymers have been developed in the Institute for Neutron Scattering by Dr J. Allgaier and Dr. L. Willner. These “hairy colloids” exhibit  deformation, as detected by neutron scattering under shear flow. High shear rates are needed to achieve appreciable deformation, due to their relatively small size. We are therefore currently investigation the possibility of using, in addition, small colloidal silica cores coated with very long polymers. We plan to investigate deformation at very low and higher concentrations, where interactions between the deformed brushes become important. These investigations are part of a European project (HUSC, Hard to Ultra Soft Colloids).

     

  • Critical Phenomena under Shear Flow (P. Lettinga, H. Wang)

    In mixtures of stearyl silica spheres and small PDMS polymers (Poly Di Methyl Siloxane) in cyclohexane, depletion attractions can give rise to gas-liquid phase separation. Non-linear microstructural response to stationary and oscillatory shear flow near the gas-liquid critical point in these systems have been studied by means of time resolved small angle light scattering. The results of both the static and oscillatory experiments can be interpreted in terms of an earlier theory on near critical microstructure under shear flow, provided that the shear induced displacement of the critical point is taken into account. The shear induced microstructural distortion of short ranged correlations, which are responsible for the displacement of the critical point, render critical phenomena under shear flow non-universal in the sense that these depend on the details of the pair-interaction potential.

  • Dynamics and Structure of "Polymer-colloids" (S. Rathgeber)

    Suspensions of polymeric particles of a colloidal size are studied by means of small angle neutron scattering and neutron spin echo experiments. This concerns the shape, internal structur and dynamics of the colloidal particles. The systems that are studied are two different kinds of dendrimers, cellulose derivatives and bottlebrush macomolecules, in cooperation with T. Pakula (Max Planck Institute for Polymer Research in Mainz). Scattering experiments and rheology measurements at higher concentration are planned. 

 

 

Structure and Dynamics of Colloids at Interfaces and near Walls
Project leader : Dr. P. Lang
 

The subjects under investigation in this project are : 

  • Structure and Dynamics of Interfaces between Coexisting Phases

    The colloidal systems that will be investigated are rigid rods, like silica coated boehmite rods and semi-flexible fd-virus (in isotropic-nematic coexistence), soft systems like internally crosslinked cylindrical micelles (in isotropic-columnar coexistence), and spheres (in gas-liquid or liquid-crystal coexistence). A surface sensitive dynamic and static light scattering set up is being built at this moment.

  • Structure and Dynamics close to a Wall and Interactions with a Wall

    Rods and spheres, mixed with several kinds of depletants (like semi flexible polymers and polyelectrolytes) will be investigated. We also plan to investigate concentration profiles, dynamics and depletion forces near a wall in mixtures of long polymers and small colloidal spheres. This will be done in cooperation with Dr. E. Eisenriegler and Dr. R Winkler (Institute Theory II). A Total Internal Reflection Microscope (TIRM) has been built for this purpose.

 

Dynamics in Equilibrium Systems
Project leader : Dr. G. Meier

The subjects under investigation in this project are :

  • Dynamics of Polymer Mixtures and Colloids under high Pressure

    Pressure is an external variable that can be used to continuously vary the compatibility of polymers. The polymers can either be free polymers or polymers bound to the surface of colloidal particles. Besides by pressure, monomer-monomer pair-interaction potentials can also be changed systematically by changing the H/D composition of the polymers. This offers the possibility to gain insight in the microscopic origin of the rich phase behaviour and dynamics of these systems. The phase behaviour and (critical) dynamics of polymer mixtures and mixtures of polymers and polymer-coated colloidal particles will be the topic of this project.

  • Phonon Dispersion in heterogeneous Systems

    Colloidal systems represent heterogeneous systems, in which the dynamics of acoustic modes will be studied. There will almost certainly be a dependence of the properties of acoustic exitations on the structural properties of the colloidal suspensions. The degree of heterogeneity can be changed continously by changing the size and/or concentration of the colloidal particles.

     

  • Rotational Diffusion of Rods near Phasetransition Lines

    Rotational diffusion of rod like colloids and polymers in the neighbourhood of a gas-liquid and isotropic-nematic phase boundary will be studied. Near a gas-liquid phase transition line, the attractive interactions between the rods will probably lead to a severe change of the rotational diffusion coefficient, since attractions favor parallel alignment of neigbouring rods over perpendicular alignment. On approach of the isotropic-nematic spinodals, the rotational diffusion coefficient tends to zero in a way that is not known, that is, the critical exponent for the rotational diffusion coefficient is as yet unknown.

  • Rotational Diffusion away from Phasetransition Lines (P. Lettinga)

    Rotational diffusion coefficients of colloidal spheres and rods in bulk solution and within porous media are investigated by means of Time resolved Phosphorescence Anisotropy (TPA) and Recovery After Photobleaching (FRAP). These experiments are performed at the University of Utrecht in collaboration G. Koenderink and prof. A.P. Philipse. Also of interest is rotational diffusion of rigid rods under stationary shear flow, where FRAP and heterodyne dynamic light scattering experiments are planned.

We are building a combination of set ups which allows one to investigate dynamics in the time range 10-13-102 s. Dynamic light scattering covers a dynamic range of 10-7-102 s. A Sandercock tandem interferometer will be used to cover the time range 10-9-10-11s. The gap between these time ranges can be covered employing a confocal interferometer. The very fast dynamics will be studied by means of Raman scattering

Biopolymers

Project leader : Dr. R. Tuinier (started 1 nov. 2001)

This project deals with composite materials of colloids and biopolymers. Not much have been done so far experimentally, since the biology laboratory is not yet finished.

 

Phenomena in Temperature Gradients
Project leader : Dr. S. Wiegand (started 1 jan. 2003)

This project deals with the study of termodiffusion and macroscopic phenomena under temperature gradients. For thermodiffusion experiments we are currently building a Forced Rayleigh Scattering set up, specialized to measure the Soret effect.

 

Correlation between Interactions and ordered Structures
Project leader : Dr. J. Hauck

Dr. J. Hauck has been at the IFF for a longer time. His work in the Institute Weiche Materie is a continuation of part of the work that has been done by J. Hauck during the past, applied to ordered structures in various colloidal systems.

 

Synthesis
Project leaders : Dr. J. Buitenhuis
  Dr. W. Sager

The aim of this project is the development of new colloidal systems, the investigation of synthesis mechanisms and the synthesis of  (known) colloidal systems for cooperation projects.

 

Synthesis of known Colloidal Model Systems

The synthesis facility should supply and further develop the synthesis of known model systems with which physical experimentation will be done within the projects mentioned above. In this respect our contacts with the University of Utrecht are very valuable.

 

Development of new model systems

The following activities for the synthesis of novel model systems are in progress :

  • Preparation of Nanostructured Materials in Self-organising Systems (W. Sager)

    This project is concerned with the characterisation of microemulsions as precipitation media for inorganic materials with at least one dimension in the nanometer range and the development of synthesis routes for nanostructured inorganic/organic composites employing the different structures encountered in microemulsion systems as templates. It is part of the PhD-project of Aurelie Autin and is performed together with Prof. R. Nolte at the University of Nijmegen.

    Though microemulsions have increasingly been utilised over the last 2 decades, and in some cases even established themselves as precipitation medium for the preparation of small uniform inorganic particles of mostly spherical geometry, little systematic work has been performed on what actually controls the size, shape, crystallinity and stability of the particles formed. Until now there is no global picture at hand describing nucleation and growth processes for the different microemulsion morphologies investigated and a generally valid theory is still out of reach.

    In this project we want to perform a systematic study on precipitation in well defined and characterised microemulsions with different morphology ranging from droplet-type microemulsions to cylindrical aggregate structures and bicontinuous microemulsions. The latter consist of an interwoven network of water and oil channels stabilised by the interfacial surfactant film. To establish a direct relation between microemulsion structure and particle morphology, the microemulsions and the precipitated inorganic materials will be characterised by phase diagram and conductivity studies, electron and atomic force microscopy, X-ray diffraction and scattering techniques. Underlying nucleation and growth processes will be studied with respect to microemulsion morphology, specific inorganic nuclei/surfactant interactions and properties of the interfacial surfactant film. Emphasis will be laid on solidifying bicontinuous structures which is of special interest for inorganic/organic nanocomposites. Employing microemulsions systems as templates for nanostructured composite materials has the advantage of offering the possibility of both simultaneous and consecutive formation of the organic and the inorganic solid phase by bringing in one precursor with the water and the other with the oil phase or the interfacial surfactant layer.

  • Synthesis of Silica Coated fd-virusses (J. Buitenhuis)

    The fd-virus is a slightly flexible rod of about 800 nm length and 6 nm width. The aim is to coat the virus by a silica layer to obtain rigid rods of variable diameter, which after using a variety of standard coatings of the silica, can be dispersed in apolar solvent to obtain cylinders with a variety  of well defined interactions. This subject is just starting, in collaborayion with the University of Utrecht.

  • Colloidal Platelets (J. Buitenhuis)

    Similar to the synthesis of colloidal boehmite rods, platelets can be synthesized. The monodispersity can be improved and surface treatment renders these platelets compatible to organic solvents. This synthesis has been developed in Utrecht.

  • Synthesis of Soft Colloidal Rods (P. Lang, L. Willner)

    The aim is to develop a model system for soft colloidal rods. These rods are synthesized by radically crosslinking of cylindrical micelles, which consist of amphiphilic blockcopolymers. This will lead to flexible colloidal rods, of which the length is about 200 nm and the aspect ratio about 20. The main problem will be to fractionate the system in order to reduce the polydispersity in length.

    The polymer synthesis know how that is available in the Institute for Neutron Scattering (Dr. L. Willner and Dr. J. Allgaier) will be of great advantage in developing certain classes of new colloidal systems.

 

Theory
Project leader : Dr. G. Naegele

The aim of this project is two-fold : (i) developing theory on subjects that are, or may become, of experimental interest to the Institute, and (ii) to assist experimentalists with devising new experiments and with data interpretation.

  • Interdiffusion and Spinodal Decomposition

    Interdiffusion in mixtures of differently sized colloidal spheres will be investigated by means of mode coupling theory. In relation to this, spinodal decomposition kinetics in binary mixtures will be studied.

  • Electrokinetic Effects in Colloids

    In particular, electrolyte friction is studied on the basis of mode coupling theory for a binary system : the large colloidal particles and the counter ions. A remarkable result is that hydrodynamic interactions play an essential role. A treatment of non-linear electrolyte friction response is within the validity of the present approach.

  • Linear Viscoelastic Behaviour of spherical Colloids

    A Green-Kubo formula for the linear shear viscosity of colloids, where hydrodynamic interactions are important, has been derived and evaluated numerically on the basis of a mode coupling approach.
