摘要: 导电聚合物因其具有良好的空气稳定性、电化学成膜性和导电性等特点,在二次电池、电色显示及固体电容器等方面都有诱人的应用前景.近年来人们研究导电聚合物的纳米结构时发现,由于超分子效应,纳米纤维中聚合物链会以平行于纤维轴向为优先取向,这种优先取向使导电聚合物纳米纤维的电导率比块材有极大提高.

Abstract: Copolymer nanofibrilla arrays composed of pyrrole and thiophene were prepared by synthesizing the desired polymer within the pores of the porous anodic aluminum oxide (AAO) template membrane. The results of SEMand TEMreveal that the obtained copolymer nanofibrillas have uniform and well-aligned arrays. The results of infrared spectra and cyclic voltammetry indicate that the obtained nanofibrilla arrays are copolymer rather than mixture of polypyrrole and polythiophene. The higher potential favored the incorporation of thiophene units into the copolymer nanofibrillas.
