Abstract
- In this work, the polyvinyl alcohol (PVA) films composited with molybdotungstovanadogermanic heteropoly acid were prepared. Infrared spectra (IR) revealed that the Keggin structure characteristic of the GeMo2W9VO405− anion was present in PVA films. At room temperature (20 °C), the conductivity of the samples of different HPA content increased from <F>2.46×10−3</F> to <F>9.92×10−3</F> S cm−1. The results indicated that they are new kind of excellent high-proton conductor. [Copyright &y& Elsevier]
