摘要
以苯乙烯和二乙烯基苯为原料,石蜡为造孔剂,采用悬浮聚合及后续热处理制得聚苯乙烯树脂基碳微球(PCS)以用作超级电容器电极材料,并对其孔结构、表面形貌及表面化学性质进行了分析。结果表明,当添加质量分数为30%的石蜡造孔剂时,所制聚苯乙烯树脂基碳微球(PCS-30%)的比表面积高达2589 m^(2)/g,其中微孔表面积为2328 m^(2)/g;在Et4NBF4-PC电解液体系下,将该材料作为电极材料制备双电层超级电容器,在0.1 A/g的电流密度条件下,电容器的比电容为106.4 F/g,相应超级电容器的能量密度为22.1 W·h/kg。
Polystyrene resin-based carbon microspheres(PCS)were synthesized through suspension polymerization method and followed by heat treatment using styrene and divinylbenzene as raw materials,paraffin wax as pore-forming agent,respectively.The as-prepared PCS were used as the electrode material for a double-layer supercapacitor,and its pore structure,surface morphologies,and chemical properties were analyzed.The results showed that,when paraffin wax of 30%was added to the raw material system,PCS-30%gave a large specific surface area of 2589 m^(2)/g,with a micropore surface area of 2328 m^(2)/g.When used as the electrode material for a double-layer supercapacitor,the obtained electrode material in the organic electrolyte of Et4NBF4-PC exhibited a high specific capacitance of 106.4 F/g and energy density of 22.1 W·h/kg at a current density of 0.1 A/g.
