摘　　要：由化学氧化法制得的聚苯胺(PANI)被不同质子酸掺杂。研究盐酸(HCl)、硫酸(H2SO4)、樟脑磺酸(CSA)和十二烷基苯磺酸(DBSA)掺杂对PANI产率、溶解性以及电导率的影响。研究发现,HCl掺杂的PANI电导率为0.263 4 S/cm、产率可达到78.83%。还讨论不同HCl浓度和不同过硫酸铵/苯胺(APS/An)的物质的量比对HCl掺杂PANI产率和电导率的影响,当HCl的浓度达到1.2 mol/L、APS/An物质的量比为0.6时,PANI的电导率和产率均为最大值。Polyanilines （PANI） doped by different protonic acid were synthesized by chemical oxidation. The effects of HC1, H2SO4, CSA and DBSA on polyaniline yield, solubility and conductivity had been researched. It had been revealed that the yield of polyaniline doped by hydrochloric acid could reach 78.83%and the conductivity of PANI was 0. 263 4 S· cm -i It also discussed that the effects of different HC1 concentration and different ammonium persulfate/aniline （APS/An） mole ratio on the polyaniline yield and conductivity. The results showed that both the yield and the conductivity of PANI were the maximal when the concentration of HC1 was 1.2 mol/L and the molar ratio of APS/An was 0.6.
