摘　　要：采用自由基溶液聚合方法,将KOH嵌入由聚丙烯酸/聚丙烯酰胺(PAA/PAAM)构成的固体凝胶中,制成具有较高机械强度的强碱性固体凝胶电解质。研究发现,固体凝胶电解质电导率接近KOH水溶液电导率,在KOH质量分数为20%时其电导率达最大值0.28 S/cm;电导率随温度的变化遵循Arrhenius原理。When KOH was embedded in PAA/PAAM gel by theway of radical solution polymerization, a strong alkaline gel electrolyte with reasonable mechanical strength was made. It was found that the conductivity of the gel electrolyte at ambient temperature was similar to that of KOH solution;the maximal ambient temperature conductivity（0.28 S/cm） was achieved at the concentration of 20 % KOH in the gel electrolyte; with the increasing of temperature, the conductivities were in accordance with Arrhenius principle.
