New hybrid guest–host nanocomposites based on polyaniline, poly(ethylene oxide) and V2O5

Abstract

New hybrid guest–host nanocomposites based on V₂O₅, in the interlayer galleries of which there are simultaneously the macromolecules of two polymers poly(ethylene oxide) and polyaniline, one being an ion-conducting polymer and the other electron-conducting, are obtained. 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 V₂O₅ results in an improvement of the charge capacity and stability during charge–discharge cycling.
