SERS studies on the ordered structure of the surface of polypyrrole nanotubules

The SERS spectra of the aligned polypyrrole tubules were studied carefully. The oriented structure of the polymer chains was cautiously discussed and the conclusion was reached that the pyrrole ring lied parallel to the alumina template tubule wall and the orientation of the polymer chains was parallel to the axle of the tubules. The relationship between the structure and the unique properties was also well explained. # 2003 Elsevier B.V. All rights reserved.
