化学法改变聚苯胺的氧化状态及其性能的研究

THE CHANGE OF OXIDATION STATE OF CHEMICALLY TREATED POLYANILINE AND STUDIES ON THEIR PROPERTIES

本文通过化学氧化与还原的方法改变聚苯胺的氧化状态,并借助元素分析,FT—IR、ESR和X射线衍射分析等对所得产物的结构和性能进行了研究。发现聚苯胺的氧化状态对其导电性和结晶性的影响很大,用化学氧化剂和还原剂可使不同氧化状态的聚苯胺相互转化,而且转化过程具有良好的可逆性。

Polyaniline is chemically oxidized and reduced to change its oxidation state. The structures and properties of the obtained products are studied by means of elemental analysis, FT-IR, ESR, X-ray diffraction, etc.. It is found that the oxidation state will strongly affect the conductivity and crystallinity of polyaniline.The forms of polyaniline with different oxidation state can be interconverted by chemical oxidant and/or reductant.
