摘要

采用原位氧化聚合法将聚苯胺插入层状V,2,O,5,的片层中，制得了聚苯胺/五氧化二钒（PAn/V,2,O,5,）纳米复合材料，并借助热失重分析（Thermogravimetric analysis,TGA）、傅立叶变换红外光谱（Fourier transform infrared spectra, FTIR）、X射线衍射（X-ray diffraction,XRD）、电导率及循环伏安测试等手段研究了,60,Co γ射线辐照对纳米复合材料结构与性能的影响。结果表明，, 60,Co γ射线辐照可使V,2,O,5,片层间的低分子量的苯胺齐聚物转化为大分子量的聚苯胺，从而提高了纳米复合材料热稳定性；同时电化学性能也得到明显改善。且辐照对纳米复合材料的层状结构几乎没有影响。

Abstract

A nanocomposite consisting of vanadium pentoxide (V,2,O,5,) and polyaniline (PAn) was prepared by ,in-situ, intercalative polymerization, and irradiation effects on structure and properties of the PAn/V,2,O,5, nanocomposite have also been investigated by using thermogravimetric analysis, FT-IR, X-ray diffraction, conductivity measurement and cyclic voltammetry. The results show that irradiation is of advantage to improvement of thermal stability and specific capacity of PAn/V,2,O,5, nanocomposite for rechargeable lithium batteries. However, irradiation has no effect on interlayer spacing of V,2,O,5, xerogel and crystalline size obviously.
