在过氧化钨酸-过氧化氢均相催化氧化体系中,在盐酸或对甲基苯磺酸的存在下合成出掺杂态聚苯胺（PANI/HCl和PANI/TSA）。反应终了后,加入碘化钾除去体系中剩余的过氧化氢。产物分离过程中,使用了抽滤法与甲苯-水共沸蒸馏法两种方法。与抽滤法相比,用共沸蒸馏法处理反应后的产物能得到高产率的掺杂态聚苯胺。使用傅立叶红外吸收光谱（FTIR）和紫外-可见光吸收光谱（UV-vis）研究了两种掺杂态聚苯胺的化学构造变化。使用四端子法测定了掺杂态聚苯胺的导电性能,其导电率能达到10-3S/cm数量级。

The doped polyaniline(PANI) was synthesized by using tungstic acid peroxide as a homogeneous catalyst in the presence of hydrogen peroxide and hydrochloric acid or 4-methylbenzenesulfonic acid(TSA).The residual hydrogen peroxide in the reaction system was decomposed by addition of KI after chemical polymerization.The filtration or azeotropic distillation of methylbenzene and water was used in the separation of the doped PANI.The product was obtained by the azeotropic distillation in good yield as compared with the filtration.The structural changes of the doped PANI were observed by FTIR and UV-vis.The electric conductivity of the doped PANI was measured by four-point terminal method.The electrical conductivity of the resulting doped PANI film is in the order of 10-3 S/cm.
