摘要
室温下,以全氟磺酸溶液(Nafion)和离子液体1-乙基-3-甲基咪唑三氟甲烷磺酸盐([Emim]OTF)为软模板、过硫酸铵(APS)为氧化剂,制备聚苯胺材料(NL-PANI)。SEM结果表明,NL-PANI为尺寸均一、孔隙分布均匀的三维纳米纤维状结构。以NL-PANI为活性物质,1.0 mol·L^(-1) H_(2)SO_(4)为电解液,组装成对称性超级电容器,在0.1 A·g^(-1)电流密度下,NL-PANI的比容量为650.49 F·g^(-1),当电流密度从0.1 A·g^(-1)增大到1.0 A·g^(-1)时,比容量保持率为82.46%,说明NL-PANI具有优异的电容性能和倍率性能。
Polyaniline(NL-PANI)was prepared with ammonium sulfate(APS)as oxidant,and Nafion and 1-ethyl-3-methylimidazolium trifluoromethanesulfonate([Emim]OTF)as soft template at room temperature.SEM results show that NL-PANI is 3D nanofibrous structure with uniform size and pore distribution.The symmetric supercapacitor was assembled with NL-PANI as active substance and 1.0 mol·L^(-1) H_(2)SO_(4) as electrolyte.At a current density of 0.1 A·g^(-1),the specific capacitance of NL-PANI is 650.49 F·g^(-1).When the current density increases from 0.1 A·g^(-1) to 1.0 A·g^(-1),the specific capacity retention rate is 82.46%.NL-PANI has excellent capacitance performance and rate performance.
