Preparation of Poly(Vinyl Alcohol)/Polyacrylate Hydrogel Polymer Electrolyte

以丙烯酸、聚乙烯醇、N,N-亚甲基双丙烯酰胺等为原料,采用水溶液聚合法制备聚乙烯醇/聚丙烯酸水凝胶聚合物基质,与6 mol/LKOH溶液制成吸液率约为173%凝胶聚合物电解质,产物在室温时电导率可达567.3 ms.cm-1。并且讨论了聚乙烯醇/聚丙烯酸凝胶聚合物电解质的导电机理及凝胶聚合物吸液率与电导率的关系。

A new hydrogel polymer poly（vinyl alcohol）/polyacrylate was prepared using acrylic acid,poly（vinyl alcohol） and N,N-methylenebisacrylamide as raw materials by the solution polymerization.A hydrogel polymer electrolyte was gotten by mixing it with 6mol/L KOH solution with the swelling ratio up to 173% and the conductivity 567.3ms·cm^-1 at the room temperature.Conduction mechanism of the hydrogel polymer electrolyte and the relationship between the swelling ratio and the conductivity were also discussed in the paper.
