Interfacial Properties of Isotropic Semi-Flexible Polymer Blends
Keyword(s):
AbstractWe analyze interfacial behavior in binary blends of polymers with different flexibilities. Our starting point is a free energy functional calculated from a microscopic model of wormlike chains. We show how this functional can be used to calculate interfacial properties within the Cahn-Hilliard approach. Here we present preliminary results applicable to chains that are globally coil-like. At the interface between two isotropic phases, each rich in a different polymer, we find that the polymers tend to be extended parallel to the interface. Thus their shape is oblate rather than spherical at the interface.
