摘要
利用布朗动力学方法研究了ACB三嵌段粒子的分级自组装过程.由第一级组装得到的结构作为第二级组装的初始构型,通过调控体系中补丁B部分的吸引强度和补丁粒子的浓度,研究了第二级组装过程中形成有序结构的影响因素.通过设计组装模型、组装规则和组装路线,得到了蜂巢状网络结构和金刚石状结构.结果表明,在较高的吸引强度和适当的浓度下,可以得到更多且更规整的蜂巢状结构;较高和较低的吸引强度和浓度都不利于金刚石状结构的形成.
The hierarchical self-assembly of ACB triblock patchy particles were investigated via Brownian Dynamics( BD) method. The self-assembly product of first stage was set as the initial structure for the second stage self-assembly. By regulation the interaction between patch B as well as the concentration of patchy particles,the factors of influence the ordered structures were studied. Via properly designing the assembly models, routes and rules,we can obtain the formation of honeycomb network structure and diamond structures,respectively. The results revealed that the strong attraction between patch B was good for honeycomb network structure formation in solution with suitable patchy particle concentrations. But it was necessary to choose the appropriate attraction between patch B and the concentration to get the diamond mounted structures.
