| 摘 要： | 以苯胺为单体、过硫酸胺为氧化剂,由化学氧化聚合法在磺基水杨酸和硫酸的复合酸的水溶液中合成导电聚苯胺,并通过压片法、激光粒度分析、扫描电镜、差热分析及红外光谱对掺杂态聚苯胺的电导率、表面形貌及结构进行了研究.结果表明,复合酸掺杂聚苯胺的热稳定性比仅用硫酸掺杂聚苯胺的有了很大的提高;所得导电聚苯胺的粒度分布比较均匀(平均粒径约15.4μm);复合酸掺杂使聚苯胺分子链上的电荷呈离域化,掺杂程度提高.

| Abstract: | Polyaniline (PAn) were synthesized using aniline as monomer and ammonium persulfate as oxidant in mixed acid solution by chemical oxidization polymerization. The properties of as-synthesized PAn were studied by squash method,laser granularity analysis,thermogravimetric analysis(DSC-TGA),SEM and FT-IR. The results showed the thermal stability of the as-synthesized PAn was better than that prepared in H2SO4. The particle size of PAn is uniform with an average size of about 15.4um. The good conductivity of as-... |
