| 摘 要： | 制备了V2O5/DBSA-PANI复合材料,用XRD、IR及SEM对材料进行了表征.结果表明,复合材料为片状,V2O5和DBSA-PANI之间有化学键形成;材料的恒流充放电性能测试结果表明.当电流密度为0.2～0.8 mA.电压范围为-0.2-0.8 V(vs.SCE),电解液为1 mol/L KNO3溶液时,所得材料具有良好的电容特性,复合材料的比电容比单独的V2O5明显提高,而循环性能比单独的DBSA-PANI好.电压范围为-0.2～0.8 V(vs.SCE),以2～10 mV/s扫描速率进行循环伏安测试,该复合材料均表现出良好的赝电容性能.

| Abstract: | V2O5/DBSA-PANI composite materials were prepared in the paper.The sample was characterized by means of XRD, IR and SEM.The results show that the shapes of V2O5and V2O5/DBSA-PANI are layers and bonding roles existed between V2O5and DBSA-PANI.Its electrochemical properties were determined by cyclic voltammetry and charge-discharge tests in aqueous electrolytes.At the current density range of 0.2-0.8 mA and voltage range of-0.2-0.8 V(vs.SCE) in 1 mol/L KNO3 electrolyte , V2O5/DBSA-PANI composite materials exhi... |
