摘　　要：本文以吡咯为单体、三氯化铁为氧化剂,化学氧化合成了聚吡咯,采用反相微乳聚合法制备十二苯磺酸(DBSA)掺杂的导电聚吡咯(PPy)纳米复合材料。用IR、XRD、SEM和电化学测试对复合材料进行表征。结果表明:复合材料中DBSA和PPy存在一定程度上的相互协同作用。循环伏安表明,在KOH溶液中,具有较高导电性的复合材料使其电化学性能得到优化。Polypyrrole is synthesized by chemical oxidation from pyrrole. Conducting DBSA-PPy is fabricated by reverse microemulsion polymerization. DBSA-PPy composites were characterized by means of IR, XRD, SEM and electrochemical tests. Results show that in the composite exists cooperated interaction between DBSA and PPy. Cyclic vohammetry showed that the composite had a better electrochemical activity in KOH solution.
