我们应用最先进的，大规范蒙特卡罗模拟来确定嵌段共聚物恒星溶液的自组织和相行为。后者由含有N个单体的f - ab嵌段共聚物组成，每个嵌段共聚物含有亲溶剂嵌段a和疏溶剂嵌段B，它们在它们的a侧有一个共同的中心。我们改变了聚合度N和嵌段共聚物臂的相对组成，并研究了系统中巨相和微相分离之间的相互作用。文中还给出了增加星臂数所产生的影响的初步结果。
We apply state-of-the-art, Grand Canonical Monte Carlo simulations to determine the self-organization and phase behavior of solutions of block copolymer stars. The latter consist of f AB-block copolymers with N monomers each, which contain a solvophilic block A and solvophobic block B, and which are tethered on a common center on their A-side. We vary the degree of polymerization N and the relative composition of the block copolymer arms and investigate the interplay between macrophase and microphase separation in the system. Preliminary results of the effect of increasing the number of arms, f of the stars are also presented.
