显微拉曼光谱研究导电高分子复合微米管

Microscopic Raman Spectroscopy Studies on Conducting Polymeric Composite Nano-tubules

利用氧化铝模板在三氟化硼乙醚溶液中电化学聚合苯和噻吩制得聚苯/聚噻吩复合微米管。通过扫描电子显微镜和显微拉曼光谱研究了复合微米管的形态与结构。结果表明:复合微米管具有三个明显的区域,它们分别是聚苯区,聚苯/聚噻吩复合区和聚噻吩区。

Aligned composite microtubules of poly (p-phenylene) and polythiophene were generated by successive electrochemical oxidations of benzene and thiophene in freshly distilled boron trifluoride-diethyl etherate solution and using a microporous alumina membrane with pores of 200 nm as the template. The morphology and chain structure of the composite microtubules were studied by scanning electron microscopy and microscopic Raman spectroscopy. The results demonstrated that the composite nanotubules had three composition zones: a zone of pure poly(p-phenylene), an overlap zone and a zone of pure polythiophene.
