论文摘要
块共聚物熔体提供了一个独特的模板，可以控制纳米颗粒的位置和对齐，因为它们能够自组装成周期性的有序结构。活跃的布朗颗粒显示与块共聚物共聚，从而导致出现的有组织的结构。块共聚物充当软限制，可以控制活性布朗颗粒的自我构造，包括界面分离和选择性纳米颗粒。在中等的活动状态下，活性的布朗颗粒可以形成有组织的结构，例如偏振火车或旋转涡流。在高活性下，由于聚合物自组装与活性的布朗自我强化，聚合物和胶体时间尺度的对比会导致粒子群体造成粒子群的粒子群。
Block copolymer melts offer a unique template to control the position and alignment of nanoparticles due to their ability to self-assemble into periodic ordered structures. Active Brownian particles are shown to co-assemble with block copolymers leading to emergent organised structures. The block copolymer acts as a soft confinement that can control the self-propulsion of the active Brownian particles, both for interface-segregated and selective nanoparticles. At moderate activity regimes, active Brownian particles can form organised structures such as polarised trains or rotating vortexes. At high activity, the contrast in the polymeric and colloidal time scales can lead to particle swarms with distorted block copolymer morphology, due to the competition between the polymeric self-assembly and the active Brownian self-propulsion.
