摘　　要：在1-丁基-3-甲基咪唑硫酸氢盐(BMIHSO_4)离子液体中,采用循环伏安法合成了苯胺和环氧丙烷共聚物(PAN-PPO),并与聚苯胺(PAN)进行了对比。结果表明:在相同条件下,PAN-PPO的电合成速度远大于PAN。同时采用红外光谱FTIR和扫描电子显微镜SEM对PAN-PPO进行了表征,FTIR表明苯胺和环氧丙烷在BMIHSO_4中发生了共聚,SEM表明PAN-PPO由直径小于80 nm的纳米纤维组成。Polyaniline-poly(propylene oxide)(PAN-PPO)was prepared in an ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate(BMIHSO_4) by cyclic voltammetry.In comparison with polyaniline(PAN),the polymerization rate of PAN-PPO in BMIHSO_4 was much higher than that of PAN.In addition,PAN-PPO was characterized by FTIR spectrometry and scanning electron microscopy(SEM).The result of FTIR showed that aniline and propylene oxide have been copolymerized in the ionic liquid BMIHSO_4,and SEM photograph showed that PAN-PPO was composed of nanofibers with diameter about 80 nm.
