摘要：以盐酸为掺杂剂,通过氧化共聚法制备了聚苯胺(PAn)-g-聚乙二醇(PEG)共聚物粒子,用红外光谱、透射电镜对粒子的结构进行了表征,并对共聚物粒子的热稳定性、导电性能进行了测试。结果表明,PAn-g-PEG共聚物粒子具有很好的热稳定性,且经过LiClO₄掺杂后兼具离子-电子导电性能,当n[Li⁺]/n[EO]=0.1时,共聚物粒子的导电率最大。

Abstract: The polyaniline-polyethandiol(PAn- g- PEG) copolymers were synthesized by chemical oxidative copolymerization. The copolymer particles were characterized by FT- IR and TEM. The thermostability and conductivity were measured. The results show that the copolymer particles are thermostable under 100 ℃ and have ion-electron conductivity doped LiClO₄. They also have the highest conductivity when the n[Li⁺ ]/ n[EO]= 0.1.
