摘要：采用Dawson结构钨磷酸（P2W18）与有机聚合物基质（聚乙二醇、聚乙烯吡咯烷酮或壳寡糖）进行复合，制备了一系列有机一无机复合高质子导体材料（PEG／P2W18、PVP／P2W158、COS／P2W18）．通过红外光谱对Dawson结构钨磷酸进行了表征，并通过电化学阻抗谱对Dawson结构钨磷酸及其复合高质子导体材料的质子电导率进行了研究．结果表明P2W18、PEG／P2W18、PVP／P2W18和COS／P。W，8的质子电导率分别为：4．73×10^3 3.71x10^-4、5．75×10^-3和2．78x10-4 S·cm^-1，为新型固体高质子导体。

In this paper, a series of organic-inorganic hybrid high proton conductor materials (PEG/ P2Wls, PVP/P~WIs, COS/P2WI8) were prepared by octadecatungstodiphosphoric heteropoly acid with Dawson structure composited with polymer matrix (polyethylene glycol, polyvinylpyrrolidone, chitosan). The octadecatungstodiphosphoric heteropoly acid with Dawson structure was characterized by infrared spectrum, and the proton conductivity of octadecatungstodiphosphoric heteropoly acid with Dawson struc- ture and its hybrid high proton conductor materials was measured by electrochemical impedance spectra. The results show that the proton conductivity of PEW18, PEG/Pc W18 ,PVP/P2Wl8 ,COS/P2W18 was 4.73x10^-3, 3.71x10^-4,5.75x10^-3 and 2.78x10^-4 S·cm%-1 at 18 ℃, respectively. They are new solid high proton conductors.
