甲基橙掺杂聚吡咯纳米管的合成及其性能

Synthesis and performance of polypyrrole nanotubes doped with methyl orange

通过化学氧化法,以Fe(NO3)3为氧化剂,甲基橙(MO)为掺杂剂合成了聚吡咯纳米空心管.通过FT-IR、SEM、TEM和电导率测试等研究了氧化剂和掺杂剂等对聚吡咯形貌结构和电导率的影响;并将聚吡咯纳米管涂覆在工作电极表面制作而成的修饰电极经循环伏安法测试表明具有良好的氧化还原可逆性.

Polypyrrole nanotubes are one kind of the most promising materials for potential applications.In this paper,polypyrrole nanotubes doped with methyl orange（MO） were prepared by using Fe（NO3）3 as the oxidant.The effects of Fe（NO3）3 and MO on the morphology and conductivity of the nanotubes have been studied by FT-IR,SEM,TEM and conductivity test.Moreover,the cyclic voltammetry indicated that the polypyrrole nanotubes modified electrode possessed the redox reversibility.
