动态密度泛函理论在梳型共聚物自组装中的应用

Using the dynamic mean-field density functional method, we explore microphase of ABC comb copolymers in a two-dimensional space. Simulations are carried out for different copolymer architectures. The application of this method to comb copolymers melts leads to some microphases patterns, such as corolla, lamellae and knitting nap pattern, etc. By systematically varying the Flory-Huggins parameters, phase diagrams are made for the two different systems. When both volume fractions and interaction energies of three species are same for the two systems, the stable microphases depend greatly on their architectures.
