Abstract

Polyaniline (PANI) "sunflowers" made of arrays of oriented nanorods were synthesized by chemical oxidative polymerization of aniline in the presence of cetyltrimethylammonium bromide (CTAB) and suitable concentration of HNO3 at about 0 degrees C (ice bath). The reaction conditions, such as the concentration of reagents and reaction temperature were systematically investigated and controlled on the preparation of PANI "sunflowers". The results also suggest that HNO3 probably plays a key role in forming PANI "sunflowers". A possible forming mechanism of the PANI nanostructures is offered.

摘要

由取向纳米棒阵列构成的聚苯胺（PANI）“向日葵”是在十六烷基三甲基溴化铵（CTAB）存在以及约0℃（冰浴）下合适浓度的硝酸存在的条件下，通过苯胺的化学氧化聚合反应合成的。在制备聚苯胺“向日葵”的过程中，对诸如试剂浓度和反应温度等反应条件进行了系统研究和控制。结果还表明，硝酸可能在聚苯胺“向日葵”的形成过程中起关键作用。本文提出了一种聚苯胺纳米结构可能的形成机制。
