摘要/Abstract

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: For the first time, the supercapacitor based on the hydrogel-polymer electrolyte which consisted of the cross-linking of polyvinyl alcohol-glutaraldehyde (PVA-GA) using 2-acrylamido-2-methyl propane sulfonic acid (AMPS) as solicitation reagent was assembled. The gel polymer electrolyte was characterized by FTIR and AC impedance. The maximum ionic conductivity is 1.23 mS/cm at room temperature. The electrochemical properties of the supercapacitor were investigated by cyclic voltammetry, AC impedance spectra and constant current charge-discharge curve. The results show that the specific capacitance reachs 139 F/g with AMPS of 1.0 g and 0.05 mL of 5 %(by mass) GA. And the specific capacitance still retained above 80% after 50 times of charge-discharge.

Key words: 2-Acrylamido-2-methyl propane sulfonic acid (AMPS), polyvinyl alcohol, hydrogel-polymer electrolyte, supercapacitors
