摘要: 以聚氧乙烯(PEO)为基质,掺杂适量的钼磷酸铵或钼磷酸,制备出PEO-(NH4)3PMo12O40及PEO-H3PMo12O40质子导电聚合物电解质膜,测定了其电导率.讨论了加入(NH4)3PMo12O40及H3PMo12O40对PEO构型及Keggin阴离子的影响,分析了PEO-(NH4)3PMo12O40及PEO-H3PMo12O40复合膜质子电导提高的原因.其中PEO-(NH4)3PMo12O40质子导电聚合物电解质复合膜的室温电导率最高可达1.4×10-3S/cm.

Abstract: Polymer inorganic composite films of PEO-12-NPMA(NPMA: ammonium molybdophosphate; PEO: polyethylene oxide, Aldrich, Mw=600 000) and PEO-12-PMA(PMA: molybdophosphoric acid) have been prepared through a film casting method. The Keggin anions and the polymer molecules are linked together to form a new composite compound of PEO-12-PMA, which has a gauche conformation of PEO being changed to a certain degree. However, no new phase is observed in the PEO-12-NPMA composite film system. The protons in the composite materials form H bonds with the external oxygens of Keggin anions and the ether oxygens of PEO. The H bonding system of the PEO-12-NPMA film is superior to that of the PEO-12-PMA composite film. As a result, the conductivity of the PEO-12-NPMA film is higher than that of PEO-12-PMA film under the same condition.
