杂多酸氧化苯胺法制备D-HPA/PANI电子聚合物材料
Journal of Fudan University(2003)
Abstract
以Dawson结构杂多酸(D-HPA)为氧化剂、质子酸和掺杂剂,制备了高纯度的P2Mo18/PANI(S1)和P2Mo17V/PANI(S2)电子聚合物材料. 用红外光谱、紫外-可见光谱及X-射线粉末衍射等手段进行了表征,测定了材料的导电性和荧光性. 讨论了HPA氧化苯胺法的聚合机理. 结果表明:该材料是D-HPA掺杂的PANI杂化材料. 材料的导电率分别为σS1=5.50×10-3和σS2=1.10×10-1 S*cm-1. 当S1和S2 的激发光波长分别为423和363 nm 时, 其对应的荧光发射光的波长为521和434 nm. 这表明S1和S2为电子聚合物材料.
