均聚物/两嵌段共聚物/均聚物三元聚合物共混体系界面性质的Monte Carlo模拟
Monte Carlo Simulation of Interfacial Properties in Homopolymer/Diblock Copolymer/Homopolymer Ternary Polymer Blends
摘要
Abstract
We employed Monte Carlo simulation to investigate the effects of chain length and concentration of the diblock copolymer on the interfacial properties between two immiscible homopolymers. When the volume fraction of diblock copolymer is fixed at ψC=0. 05, as the chain length(NC) of diblock copolymer increases from 10 to 20 , the interface thickness decreases significantly;whereas with the chain length of diblock copoly-mer further increasing to NC=60, the interface thickness increases slightly. The orientation parameter q of the diblock copolymer chain enlarges with the increase of the diblock copolymer chain length, which means that the diblock copolymer is more stretched. When the diblock copolymer chain length is fixed as NC=10, as the volume fraction of diblock copolymer increases from ψC=0. 01 to 0. 05 , the interface thickness increases and the diblock copolymer chain orientation parameter q decreases, indicating that the stretching of diblock chain decreases.关键词
