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。
Doping polyaniline (PANI / HCl and PANI / TSA) was synthesized in the presence of hydrochloric acid or p-toluenesulfonic acid in a tungstic acid-hydrogen peroxide homogeneous catalytic oxidation system. After the reaction was completed, potassium iodide was added to remove the remaining hydrogen peroxide in the system. Product separation process, the use of suction filtration and toluene - water azeotropic distillation two methods. Compared with the suction filtration method, the azeotropic distillation process of the reaction product can be obtained in high yield doped polyaniline. The chemical structure changes of two kinds of doped polyaniline were studied by Fourier transform infrared spectroscopy (FTIR) and UV-vis spectroscopy. The conductivity of doped polyaniline was measured by four-terminal method, and its conductivity could reach 10-3S / cm.
