研究工作及完成情况

1. 各向异性软物质模拟模型及方法的发展

   本研究方向主要针对各向异性聚合物胶体、各向异性胶体链、具有各向异性结构单元的高分子和生物大分子等各向异性软物质体系,发展简单有效的、普适性的粗粒化模型及介观动力模拟方法。目前,我们已经成功发展了一系列普适高效的各向异性聚合物胶体模拟模型及方法,包括软碟状粒子模型、软棒状粒子模型、软两面神粒子模型、软补丁粒子模型和补丁椭球粒子模型等,开发了一款拥有自主知识产权的GPU加速模拟程序包ANISOMAST(Anisotropic Soft Matter Simulation Toolkit),为各向异性聚合物胶体结构和动力学研究提供了一套高效可行的动力学模拟方案。

    

2. 各向异性软物质体系聚集态结构与动力学

我们主要围绕各向异性聚合物胶体体系聚集态结构与动力学开展研究,阐明了多种形状和表面各向异性聚合物胶体体系聚集态结构的形成规律及动力学机理,揭示了利用各向异性聚合物胶体(如软两面神胶体粒子、软补丁胶体粒子等)的软形变和各向异性特性构筑不同超胶体结构(如仿生螺旋结构、非紧密堆积晶体结构等)的设计原则与调控机制。同时,与实验密切合作,采用理论模拟与实验研究相结合的方法,给出了实验上实现软两面神和补丁胶体粒子制备及调控的可行方案,为实验上理解软两面神和补丁胶体粒子自组装的本质和规律提供了重要的理论帮助。这些研究成果为新型功能化超胶体材料的设计和开发提供了新的思路和理论指导。
