摘要

综述了使用计算机模拟方法研究在本体状态下形成柱状结构的线形二嵌段和三嵌段共聚物在平行板间和纳米圆孔内的自组装结构.研究发现，嵌段共聚物体系在受限状态下自组装可以得到与本体状态下不同的纳米结构，调整受限状态的物理化学性质可以调控受限体系的相行为，从而诱导体系形成特定的结构.模拟研究还发现不同相分离强度和链结构的体系，在相同的受限状态下表现出不同的相行为.因此在制备纳米结构材料的研究中，人们要根据嵌段共聚物体系的特定性质，选择相应的受限环境，才能够实现有效的控制.

Abstract

Self-assembly of block polymers under confined states is found to be affected by various parameters

such as the geometry and surface effect of confined states

which make the phase behavior of polymers under confined states different from those in bulk state.A stack of novel nanostructures have been fabricated by the self-assembly of block polymers under confined states.Furthermore

to study the self-assembly process of block polymers under confined states could give a deep understanding on the phase behavior of block polymers.The similar or covered phase behaviors in bulk state could be clearly distinguished under confined states.In this review

the cylinderforming linear block polymers are detailed studied using computer simulation methods.The geometry and surface fields of confined states and the component of polymer chains are considered separately.
