Simulation study of phase separation in linear gradient copolymer/nanoparticle composites(线性梯度高分子与纳米颗粒共混体系相分离的模拟研究)

采用蒙特卡罗(Monte Carlo)结合退火技术研究了线性梯度高分子与纳米颗粒共混体系的相分离行为.模拟研究发现其相分离不但与梯度高分子的分布函数f(t)有关,还与链长、相互作用能和纳米颗粒浓度相关.随着参量的改变发现了无序相与层状相(L)或穿孔层状相(P)以及无序相与球状相(S)相变,此外,当在特定的单体A浓度时同时还出现了共混相,同时纳米颗粒随机分布在单体A区域内....
