| Abstract: | Polymer-inorganic composite films of PEO-12-TPA (TPA: tungstophosphoric acid) have been prepared. X-ray diffraction and infrared spectroscopy indicate that the Keggin anion and the polymer molecules are linked together to form a new composite compound. The addition of the 12-TPA facilitates the formation of H3O+ cations at high relative humidities. The conductivity of PEO-12-TPA reached 4.0×10－3 S?cm－1 with a molar ratio H+]/EO] of 0.025 and relative humidity 95%. |
