Towards the Molecular Design of Composite Materials

Abstract

We have extended in several ways the lattice cluster theory for the statistical thermodynamics of polymer systems. In addition to the previous treatments of the influence of monomer molecular structures, pressure, and non-random mixing, the new extensions consider the phase diagrams, the structural properties evidenced by small angle neutron scattering, the behavior of block copolymer systems, the stabilization of binary polymer blends by diblock copolymers, and the range of validity for mean field theories of polymer blends. Besides enabling the explanation of detailed, previously perplexing experimental data, the theory has been used to provide predictions, subsequently verified, concerning the pressure dependence of polymer properties and the possibility for ordering in block copolymers upon heating.
