Preparation and Conductivity Study of Hybrid High Proton Conductor Materials Composited with Octadecatungstodiphosphoric Heteropoly Acid with Dawson Structure
Abstract：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.
