The preparation of such ternary nanocomposites is realized by the insertion of polyaniline into the structure of the preliminary prepared, soluble, two-component poly(ethylene oxide)-V2O5 nanocomposite either by intercalative polymerization of aniline in situ, or by direct intercalation of conducting polymer macromolecules. Intercalation of the polymers is confirmed by physicochemical analysis. The presence of two polymers with different types of electrical conductivity inside V2O 5 results in an improvement of the charge capacity and stability during charge-discharge cycling. 关键词: Nanostructured materials;Vanadium compounds;Polymers;Heat conduction;Discharge (fluid mechanics);Intercalation compounds;Interlayer galleries;Ion-conducting polymers
