摘　　要：以聚氧乙烯(PEO)为基质,在其中掺杂适量的钨磷酸,制备PEO-H3PW12O40质子导电聚合物电解质膜.XRD及IR测试表明体系中Keggin阴离子与PEO链相互作用形成新的化合物;Keggin阴离子的存在有利于水合质子的形成.PEO-H3PW12O40复合膜的电导率室温最高可达4.0×10-3S?cm-1.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 formarion 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%.
