摘要

聚硅烷是一类链骨架中仅含硅原子的高聚物，主链的上的非定域σ键电子赋予了聚硅烷独特的光电性质，也是制备陶瓷材料的先驱体。电化学法是最近兴起且具发展前景的一种合成聚硅烷的方法，它是通过电解池中阴极还原氯硅烷来制取高聚物，反应条件温和，且能大大拓宽聚硅烷的功能化。本文就聚硅烷的电化学合成的实施方法;影响因素包括电解槽类型、电极材料、支撑电解质和溶剂、电极换向时间、极板间距、电流密度等作了简要介绍;并对合成机理和近期研究进展进行了简要概述。

Abstract

Polysilane is a kind of polymer with it' s backbone consisting of silicon atoms only. It can be used as opto-electronic materials and the precursor of ceramic. Electrochemical reduction is a novel synthetic method of polysilane

which was developed recently years and possesses good prospect. It is through cathodic reduction of chlorosilane in electrolysis cell to obtain polymer

it can broaden the scope of functional polysilanes

since the reaction conditions are mild. This review presents a brief account of the electrochemical synthesis of polysilane

including the implementation method

the influence factors such as cell type

electrode material

supporting electrolyte and solvent

the switching time of electrode

the distance of electrodes

electric current density. The synthesis mechanism and the recent research evolution were introduced too.
