在造纸行业中作为废液的木质素磺酸盐是一种含有甲氧基和酚羟基的生物质衍生物,由于具有可逆的氧化还原反应而提供赝电容.但木质素磺酸盐的导电性低,从而不能直接作为超级电容器电极.本文在含木质素磺酸钠(Lig)的体系中原位聚合吡咯(Py)制备了具有导电性能的木质素磺酸钠/聚吡咯复合材料(LP).通过扫描电镜(SEM)和傅里叶红外光谱(FTIR)测试对其形貌和结构进行表征.结果表明:当Lig与Py质量比为1∶1和电流密度为1 A/g时,复合材料具有高的比电容(346.8 F/g),相比于单纯聚吡咯(PPy)的比电容提高了约50 F/g.而且当电流密度从1 A/g升高到10 A/g时,LP1的倍率性能高达60.8%,比PPy提高了9.3%.在高电流密度10 A/g时,复合物LP1经过1 000次恒电流充放电后仍保留了47%的电容值,表明复合物LP1表现出好的循环稳定性.
