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。
Polyaniline is the main raw material for the preparation of electrode materials. The doping of carbon nanotubes and nano-copper can improve their conductivity and specific capacitance. Polyaniline / nano-copper / carbon nanotube composites with core-shell structure with nano-copper / carbon nanotube as core and polyaniline as shell were prepared by in-situ polymerization using ammonium persulfate as oxidant. The results of cyclic voltammetry of polyaniline doped with different mass fraction of nano-copper / carbon nanotubes show that when nano-copper / carbon nanotubes account for 15% of ternary polymer, polyaniline / nano-copper / carbon The highest specific capacitance of the nanotube composite was 2102.57 F · g-1.
