Abstract

Recently we have formulated a simple Monte Carlo model¹ for the study of the photomechanical effect in polymeric fibers pumped with a linearly polarized laser beam.^2–4 The model fiber is a host - guest system consisting of the polymeric matrix and azodye chromophores, which undergo multiple trans - cis - trans cycles when illuminated by linearly polarized light. Current paper is focused on the topic so-far neglected in,¹ closely related to the hypothetical cooperative mechanism of stress relaxation^2–4 – on the characterization of local voids in computer-generated polymeric matrix. We study void-size distributions and void-void correlation functions.
