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...
We reported here the preparation of Fe 3 O 4 -polypyrrole (PPy) nanocomposites with both magnetic and conducting properties. The magnetic properties of the resulting composites were investigated by vibrating sample magnetometer (VSM). The Fe 3 O 4 -PPy nanocomposites had coercive force from 98.4 to 116.3Oe and saturation magnetization from 0.268 to 9.23emu/g with the...
