摘　　要：采用化学氧化法,在规格为25 V/10μF的卷绕式铝电解电容器芯子中,以过硫酸铵为氧化剂合成了聚苯胺。分别考察了单体用量、氧化剂浓度以及掺杂剂种类与浓度对铝电解电容器容量和损耗的影响。结果表明:对甲苯磺酸的浓度为1 mol/L、过硫酸铵的浓度为0.7 mol/L时,所制备的铝固体电解电容器有较低的损耗和较大的容量。Polyaniline was prepared by chemical polymerization in 25 V/10 μF aluminum electrolytic capacitors. The paper also studied the influence of aniline concentration, oxidant concentration, the types of dopants and their concentration on capacitance and dissipation of capacitors. Results showed that aluminum solid electrolytic capacitors obtained lower dissipation and larger capacitance by using 1 mol/L Para-toluenesulfonic acid as dopant, 0.7 mol/L （NH4）2S2O4 as oxidant.
