abstract = {It has been shown that the thermodynamics of bicontinuous
microemulsions can be tailored via the addition of various
different amphiphilic polymers. In this manuscript, we now
focus on comb-type polymers consisting of hydrophobic
backbones and hydrophilic side chains. The distinct
philicity of the backbone and side chains leads to a
well-defined segregation into the oil and water domains
respectively, as confirmed by contrast variation small-angle
neutron scattering experiments. This polymer–microemulsion
structure leads to well-described conformational entropies
of the polymer fragments (backbone and side chains) that
exert pressure on the membrane, which influences the
thermodynamics of the overall microemulsion. In the context
of the different polymer architectures that have been
studied by our group with regards to their phase diagrams
and small-angle neutron scattering, the microemulsion
thermodynamics of comb polymers can be described in terms of
a superposition of the backbone and side chain fragments.
The denser or longer the side chain, the stronger the
grafting and the more visible the brush effect of the side
chains becomes. Possible applications of the comb polymers
as switchable additives are discussed. Finally, a balanced
philicity of polymers also motivates transmembrane migration
in biological systems of the polymers themselves or of
polymer–DNA complexes.},
