Non-Fickian Diffusive Transport in Modern Polymeric Materials

Abstract

We have developed a model for the theoretical description of large classes of problems involving diffusive transport and mechanical relaxation in polymers undergoing glass and rubber transitions. The derivation and details of the model have been described in previous progress reports. In the final year of AFOSR support we proceeded simultaneously in two directions, namely to formulate and solve moving boundary problems for the penetrant fronts and to investigate the implications of the 'forbidden shock' regions for diffusive systems.
