Computer simulation of multiblock-copolymers in presence of colloidal particles

摘要

The results of Monte Carlo computer simulation of systems containing AB-copolymer chains and colloidal particles are presented. The regular multiblock copolymers were studied, and the strong dependence of the shape of formed structures on the block length in the primary structure of copolymer chain was obtained. For system with long blocks of monomeric units the microphase separation and well-defined microstructures were observed. The colloidal particles and the attracting monomeric units of copolymer chains form the "pumice-stone"-like structure. In this structure colloidal particles look like bubbles in massive aggregate of attracting monomeric units. On the contrary, for short blocks no microstructures were formed, and polymer chains formed a well distributed spatial structure like a web. [References: 14]
