Stable monolayer of polyaniline doped with camphor sulfonic acid at the air water interface has been obtained and has been successfully deposited by Langmuir-Blodgett technique onto CaF2 substrate. IR and UV-Vis-NIR spectra show that the doped molecules dedoped partially from the PANI backbone during the monolayer compression or deposition. Gas sensing measurement indicates that the doped polyaniline LB film was sensitive to ethanol vapor at room temperature.

Key words: LB film, Doped polyaniline, Conducting polymer
