不同酸搀杂对聚苯胺的结构和形貌的影响

Structure and morphology of polyaniline influenced by different acid doped

以过硫酸铵为氧化剂,苯胺为单体,不同酸的水溶液为溶剂,采用化学氧化法合成了聚苯胺。利用扫描电镜(SEM)、红外光谱(FTIR)对制备的聚苯胺的结构和形貌进行了表征和分析。结果表明,不同酸掺杂的环境下,聚合而成的聚苯胺的结构和形貌存在一定的差异。

Polyaniline is prepared by chemical oxidation synthesis method with persulfate as oxidant, ani- line as monomer, different acid as solvent. The structure and morphology of polyaniline prepared is charac- terized and analyzed using scanning electron microscopy （SEM）, infrared spectroscopy （FTIR）. The re- suits showed that there are some differences on the structure and morphology of polyaniline under different acid doping.
