摘要
木文用FT-IR、ESR、XPS等研究了聚苯胺的质子酸掺杂机制。结果表明聚苯胺掺杂时的质子化反应优先发生在分子链中的醌亚胺结构单元的氮原子上,并产生了分子内氧化还原反应而形成阳离子自由基。质子所带的电荷由于共轭作用能较好地离域到邻近苯环及对位氮原子上。
The protonic acid doping mechanism of polyaniline was studied by FT--IR, ESR,XPS, etc. The results have shown that the doping of polyanilinc is a protonation pro-cess in which the quinone imine nitrogen atom is preferential.The internal redox reac-tion in molecular chain resulted in the formation of radical cation whose charges wouldbe delocalized in the neighboring benzene ring and its para--nitrogen atom.
