摘要
本文采取改进聚合法制得聚苯胺,用盐酸或磷酸对本征态聚苯胺掺杂,获得盐酸掺杂聚苯胺(PANI/HCl)和磷酸掺杂聚苯胺样品(PANI/H3PO4)。并对这些样品进行表征和热分析,发现掺杂态聚苯胺的紫外可见光吸收和红外吸收均有不同程度的红移,其中对阴离子较大的红移最大。热分析表明本征态和掺杂态聚苯胺都具有很好的热稳定性。
In this paper,PANI was synthesized through the chemical synthesis method improved,and doped polyaniline was gained by casting and doping in ammonia,and then doped with hydrochloric acid and phosphoric acid respectively,subsequently the polyaniline samples were given by the proton acid dopant.Then characterize them with UV-vis spectra and thermal infrared spectral analysis.The results showed that doped polyaniline displayed different red shift in visible light absorption of ultraviolet and infrared absorption under the synthesis method improved,especially for anions.Moreover the samples of PANI have good thermal stabilities.
