摘要
两亲性嵌段共聚物因其易形成胶束或囊泡等自组装结构被广泛应用于食品、化妆品、医药等领域。本文采用耗散粒子动力学方法,模拟研究助溶剂在两亲性嵌段共聚物自组装过程中起到的重要作用及其对最终聚集结构的影响。我们通过改变助溶剂与水之间的作用参数,体现助溶剂种类的不同。研究发现,助溶剂与水的相容性是控制形成球状胶束、棒状胶束、蠕虫状胶束以及囊泡等结构的关键因素。
In this study, we use dissipative particle dynamics method to study the self-assembly of block copolymer in dilute solution. We change cosolvent characteristics and find the compatibility between water and cosolvent plays a key role on determining aggregate structures of amphiphilic block copolymers.
