摘要
Polyaniline films prepared by Langmuir-Blodgett technique were characterized by X- Ray diffractometry and Raman spectroscopy. The obtained results were compared with those from secondarily doped samples treated with HCSA and m-cresol. When LB films were doped with HCl vapour, the Raman spectrum obtained is different form that of PANI/HCl samples prepared by chemical or electrochemical polymerization, being very close to spectrum of PANI/CSA/m-cresol samples. In LB films a great increase in the intensity of the band correponding to free carriers indicates the important role played by the extended conformation and conductivity.
