FT-IR spectra shows that the polyaniline is present primarily in the emeraldine salt form, and the polymeric chains interact with inorganic framework, most likely via V=O…HN hydrogen bonding. XRD,TG and DSC indicate that the lamellar structure of the V_2O_5 is preserved, PAn chains eliminate water form the interlamellar region and are partially inserted between the layers, and exist with extended-chain conformation owing to the confined environment.Electrochemical investigation in the range of 1.8~3.8V vs.

红外光谱表明复合物中PAn主要以导电聚苯胺盐的形式存在，PAn链与V_2O_5晶格之间可能形成了V=O…HN氢键。X射线衍射、热重和差示扫描量热证实了PAn/V_2O_5复合物保持了较规整的层间排列结构，PAn取代了V_2O_5干凝胶中的层间水而部分嵌入其片层间，由于受空间的限制，PAn分子链以比较伸展的链构象存在。
