摘　　要：利用耗散粒子动力学模拟方法研究了二维蝌蚪型嵌段共聚物的微观相分离,得到了相形貌与蝌蚪型嵌段共聚物尺寸的依赖关系.通过计算结构因子,对相图的结构进行了分析.模拟结果揭示了本体中影响蝌蚪型嵌段共聚物微观相分离的主要因素.Dissipative particle dynamics simulations are carried out to study the microphase separation ofTadpole-like block copolymer copolymer, we find various mo characters of morphologies. Th Tadpole-like block copolymers in two dimensions. By systematically varying the size of Tad-like block rphologies. By calculating the structure factor of morphologies, we got the e results reveal the main factors that affect the microphase separation of in melts,
