摘要

嵌段共聚物由于自身嵌段之间的热力学不相容性

容易发生微相分离而形成质子传导通道

并且采用可控活性聚合的方法可设计合成具有特定拓扑结构嵌段共聚物

使之成为最具潜力的一类质子交换膜材料。本文从用于质子交换膜的嵌段共聚物的微相分离热力学理论出发

分析了影响嵌段共聚物微相分离的各类因素

其中包括磺化度、共聚物拓扑结构、嵌段长度、嵌段序列分布、微观聚集结构以及表面形貌等

并对该领域未来的发展做了展望。

Abstract

Block copolymer is becoming one of the most promising candidates for proton exchange membranes applications owing to two distinguish advantages. Microphase separation of block copolymers easily occur to form proton conductivity channel due to thermodynamic incompatibility between their own blocks

and an abundant topologies of block copolymers could be synthesized through controlled living polymerization. This review briefly introduce the microphase separation thermodynamics theories of block copolymers

and analyze the various factors influencing the microphase separation of block copolymers

including sulfonation degree

copolymers topologies

block length

block sequence distribution

micro-aggregated structure and the surface morphology. Finally

the future research tendency in these fields is also prospected.
