abstract = {A tight connection of scattering to thermodynamic models is
missing for clay systems. A new approach called “locally
columnar model” gives an attempt for making this
connection. The scattering model assumes an up-lining of
clay particles with strong paracrystalline order and refers
to a chemical potential/distance dependence. The
thermodynamic model assumes a bidisperse distance
distribution and gives input to the scattering model.
Experimentally, polymer/clay systems with many molecular
polymer masses were studied showing all very similar
scattering curves. While the dominating bulk phase shows
only the same weak tendency to stack formation for all
molecular polymer masses, one coexisting phase with stronger
stack formation was identified. The latter sample was used
to determine the thickness of the clay platelets with
adsorbed polymer that was then used to model the dominating
bulk phase. The comparisons to the theory revealed that (a)
most polymers are tightly bound to the clay, and (b) an
agreement between the modeling and the theory was achieved.
The main result of the experiments is the fraction of free
polymers of 1:2400 that are not tightly bound to the clay
particles.},
