摘要
分别以真空低温热处理和酸碱脱灰的兰炭为基体,将苯胺引入其孔隙和表面,并引发苯胺原位聚合,制备出兼具双电层电容和赝电容特征的兰炭/聚苯胺.FTIR、兰炭工业分析和电容性能测试表明,对兰炭真空低温热处理能破坏小分子有机物与兰炭间的弱相互作用,有效去除兰炭中的小分子有机物,有效改善兰炭/聚苯胺的电容特性,比电容和能量密度分别提高到169.4F/g和24.1 Wh/kg.对兰炭进行脱灰处理,会降低苯胺对兰炭的浸润性,减弱聚苯胺与兰炭间的界面作用,降低兰炭/聚苯胺的比电容.
Blue-coke/polyaniline composite material,which exhibits the double layer capacitance and pseudocapacitance properties,was synthesized after vacuum heat treatment and acid-base deashing respectively and through initiating the in-situ polymerization of aniline in the pores or on the surface of blue-coke.FTIR,proximate analysis of blue-coke,conductivity and capacitance tests showed that the weak interaction between blue-coke and small molecule organic compounds can be destroyed,small molecule organic compounds was removed and specific capacitance of blue-coke/polyaniline was enhanced effectively when vacuum heat treatment at low temperature.The specific capacitance and the energy density of blue-coke/polyaniline can increased to 169.4F/g and 24.1 Wh/kg.The wettability of aniline and specific capacitance was reduced and interfacial interaction between polyaniline and blue-coke was weaken when deashing treatment of blue-coke.
