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.
