Copolymer-Nanoparticles Mixture Confined in a Cylindrical Pore
首发时间:2015-04-21
Abstract:We have investigated the effect of nanoparticles(NPs) on diblock copolymer morphology under cylindrical confinement using Cell Dynamics Simulation. The nanoparticles are selective to the copolymer blocks, being repulsive to one block and attractive to the other. In comparison to the phase diagram in bulk of cylindrical confinement, more ordering structures are formed after adding nanoparticles. With the wetting strength and concentration of NPs increasing , the structures of block copolymers transform from disorder to order morphology. The effect of NPs wetting strength and concentration in different nanopore have been studied in detail. By developing a phase diagram to system morphology,we can meticulous know the phase morphology evolution.

受限在圆柱孔中嵌段共聚物和纳米粒子的混合物的自组装相行为
摘要:本文采用元胞动力学方法研究了填充纳米粒子对受限于圆柱纳米孔中的两嵌段共聚物自组装相行为的影响。纳米粒子对嵌段共聚物具有选择性,对两嵌段聚合物中的其中一相具有吸引作用,对另一相具有排斥作用。与简单两嵌段共聚物在圆柱受限下的相形貌相比,添加纳米粒子后体系形成了更丰富的相形貌。随着纳米粒子的浸润强度和浓度的增加,嵌段共聚物的相形貌由无序向有序相转变。本文详细地研究了纳米粒子的浸润强度和浓度对于受限在不同孔径下的嵌段共聚物相形貌的影响,并通过相图直观地反映了体系形貌的演化。
