笼型八聚倍半硅氧烷与聚苯胺复合物的合成与表征

Synthesis and characterization of PAn-POSS compounds

由笼型八聚倍半硅氧烷(POSS)与顺丁烯二酸在水中进行复合,形成离子形式的POSS/COOH复合物,再与聚苯胺(PAn)进行掺杂,将POSS基团引入聚苯胺,合成了掺杂态聚苯胺(PAn-POSS)。结果表明,POSS作为掺杂剂被成功的引入聚苯胺之中,POSS掺杂后的聚苯胺高温稳定性增强,电化学活性得以显著提高。

Doped polyaniline which synthesis from aniline by polyhedral oligomeric silsesquioxanes （POSS） in ice bath,and synthesized doped polyaniline（PAn-POSS） composite successfully in the end. The results showed that POSS doped into ployaniline successfully, the lower pH value eonducived to the reaction. POSS doped PAn high temperature stability enhanced and electrochemical activity is significantly improved.
