Abstract

Abstract: Dissipative particle dynamics simulations are carried out to study the microphase separation of comb-like block copolymer in two dimensions. By systematically varying the side chain lengths and the repulsion strength between the two components, we find various morphologies. For comparison, the linear and star-like block copolymers are also studied in the simulations. The results reveal the main factors that affect the microphase separation of comb-like block copolymers in melts.

Key words: Microphase separation, Dissipative particle dynamics simulations, Comb-like block copolymer
