聚吡咯/聚合物固体电解质双层复合膜研究

在聚合物固体电解质（聚乙二醇不饱和聚酯网络－LiClO4)中进行吡咯聚合原位制得了聚吡咯／聚合物固体电解质双层复合膜。用扫描电镜观察复合膜的界面结构，用循环伏安和交流阻抗法研究了复合膜的电化学杂脱掺杂性能。结果表明，聚吡咯／聚合物固体电解质双层复合膜具有相互穿插渗透的固／固密接界面结构，这种界面结构改善了聚吡咯和聚俣物固体电解质间的界面接触，提高了聚吡咯在聚俣物固体电解质中的电化学掺杂脱掺杂性能。

Preparation,Structure and Electrochemical Properties of Ppy/Solid-state Polymer Electrolyte Bilayer Composites

Ppy/solid state polymer electrolyte bilayer composites were prepared in situ by electrochemical polymerization of pyrrole in solid state polymer electrolyte (PEO LiCiO 4). The interfacial structure of bilayer composites and electrochemical doping undoping behaviour were investigated using SEM , cyclic voltammetry and frequency response analysis respectively.The results show that Ppy/solid state polymer electrolyte bilayer composites possess the interpenetrating solid/solid interfacial structure and enhanced interfacial contact, and the electrochemical doping undoping behaviour of Ppy in solid state polymer electrolyte cells has been enhanced owing to the enhanced interfacial contact.
