中文摘要：
高分子共混物的混合熵很小导致其多为热力学不相容体系而发生相分离，形成特定的时空图样。本文根据多年来我们的研究工作并结合实例，基于时间分辨的Ginzberg-Landau方法研究高分子复杂体系相分离动力学及图样选择，重点介绍剪切外场下高分子共混物及嵌段高分子的相分离，耦合化学反应的相分离，在弯曲曲面特别是球面上的相分离，以及TDGL与密度泛函理论的有机结合即动态自洽场理论在具有不同链拓扑结构的嵌段高分子体系中研究相分离动力学。
英文摘要：
Most unique spatial-temporal of polymer blends are thermodynamic immiscible because of small entropy of mixing, forming pattern. In this review, based on our recent work, we focus on the phase separation kinetics and corresponding pattern evolution of polymer system by using time dependent Ginzberg-Landau （TDGL） equation. The review contents cover the phase separation dynamics under shear for polymer blends and block copolymers, phase separation coupling with chemical reactions, and phase separation on the spherical surface. Also microphase separation dynamics of complex triblock copolymers is reviewed by means of the coupling between the TDGL and self-consistent field theory （SCFT）, namely dynamic SCFT, which consider both the dynamics and the topological characteristic of the chain.
