| 摘 要： | 以2-丙烯酰胺基-2-甲基丙磺酸（AMPS）作引发剂引发交联聚乙烯醇（PVA）-戊二醛（GA）制备水凝胶聚合物电解质并组装成超级电容器.分别由红外光谱、交流阻抗、循环伏安与恒电流充放电曲线测定该凝胶聚合物电解质及超级电容器的电化学性能.结果表明，该聚合物电解质电导率可达1.23 mS/cm（室温）.而且，以1.0 g AMPS引发0.05mL GA（5 %）与1.0 g PVA交联，制得的凝胶聚合物电解质超级电容器比电容可达139F/g，50次充放电后其值仍于80%以上.

| Abstract: | The supercapacitor based on the hydrogel polymer electrolyte prepared by the cross-linking polyvinyl alcohol-glutaraldehyde(PVA-GA) using 2-acrylamido-2-methyl propane sulfonic acid(AMPS) as an initiator were assembled.The electrochemical properties of the gel polymer electrolytes and supercapacitors were studied by FTIR,AC impedance,cyclic voltammetry and constant current charge-discharge measurements.The results showed that the ionic conductivity of the ploymer electrolyte reached 1.23 mS/cm at room tempe... |
