| 摘 要： | 以壳聚糖（CS）,聚乙烯醇（PVA）为基体掺杂不同比例NH4Cl进行共混,使用溶液浇铸法制备了CS-PVA-NH4Cl共混固态聚合物电解质膜,溶胀度均在1 000%左右。使用交流阻抗,直流极化,循环伏安对其电导率、离子迁移率及电化学稳定窗口进行测量,使用Zview软件对交流阻抗谱进行拟合。结果表明在40%NH4Cl掺杂时电导率为1.4×10-3S.cm-1,离子迁移率为0.93,电化学稳定窗口为2.0V。

| Abstract: | In this paper,CS-PVA-NH4Cl blend solid polymer electrolyte membrane is prepared via solution casting method by using chitosan(CS) and polyvinyl alcohol(PVA) as matrix blended with different amount of NH4Cl,the swelling rates of every sample are all around 1 000%.The conductivity,ion mobility and electrochemical stability of the SPE membranes are investigated by using AC impedance and DC polarization,cyclic voltammetry,and Zview software is used to fit the AC impedance spectroscopy.The results show that with 40% NH4Cl blending,the conductivity was 1.4 × 10-3S·cm-1,the ion mobility was 0.93,the electrochemical stability window is 2.0 V. |
