十二苯磺酸-聚吡咯纳米复合材料的合成与表征

Synthesis and Characterization of DBSA-PPy Nanocomposites

    摘要
  • 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。

     

    Abstract: 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 voltammetry showed that the composite had a better electrochemical activity in KOH solution.
