二次掺杂聚苯胺的合成及其导电性能的研究

Synthesis of polyaniline redoped and its conducting property

掺杂态的聚苯胺(PANI)合成是采用快速直接法合成盐酸/PANI,用氨水水解掺杂态,得到本征态PANI,再用对甲苯磺酸对PANI进行二次掺杂。在不同反应摩尔比、不同反应时间、不同反应温度下合成的对甲苯磺酸/PANI,用于测量电导率,得出优化条件。采用透射电镜(TEM)观察其形貌,并利用红外光谱和紫外光谱对其结构进行了表征。

Polyaniline was prepared using chemical method, then the product was deprotonated in the excess of ammoniura hydroxide to yield the corresponding polyaniline base, at last the polyaniline base was redoped using p-methylphe- nylsulfonic acid. P-methylphenylsulfonic acid/polyaniline （TSA/PANI） were prepared for the conductivity measurement under the condition of different reaction molar ratio, different reaction time and at different reaction temperature. The mor phoiogy of TSA/PANI were investigated using transmission electron microscopy （TEM）. The structure was characterized by IR spectra and UV-vis spectra.
