摘要
聚苯胺是制备电极材料的主要原料,碳纳米管和纳米铜的掺杂能提高其电导率和比电容值。采用原位聚合法以过硫酸铵为氧化剂,制备出以纳米铜/碳纳米管为核,以聚苯胺为壳的具有核-壳结构的聚苯胺/纳米铜/碳纳米管复合材料,通过对比不同质量分数的纳米铜/碳纳米管掺杂的聚苯胺循环伏安测试结果分析可知,当纳米铜/碳纳米管占三元聚合物的质量分数为15%时,聚苯胺/纳米铜/碳纳米管复合材料的比电容值最高,测试结果为2102.57F·g-1。
The PANI （polyaniline） is the key raw material for making electrode material. Its conductivity and specific capacitance can be improved by doping MWNT and nano-copper. A PANI/MWNTs/nano-copper composite is prepared by in-situ polymerization with using ammonium persulfate as oxidant. This material has core-shell structure with using the nano-copper as the core and PANI as the shell. The cyclic vohammetry results of the materials with different contents of Cu/MWNTs show that the highest specific capacitance of PANI/MWNTs/Cu composites can be obtained which is 2102.57 F·g^-1 when the mass fraction of nano-eopper/MWNTs is 15%.
