Abstract
Polyaniline was electropolymerized by cyclic voltammetry in the presence of camphor sulfonic acid (CSA), and the resulting film was characterized by solubility tests, UV-Vis absorption, electron mircroscopy, X-ray diffraction and conductivity measurements. The use of the functionalized acid - CSA - made it possible to obtain the as-electropolymerized polymer (in the doped state) soluble in organic solvents such as m-cresol and chloroform. The UV-Vic spectra of PAni-CSA in m-cresol presented a free-carrier tail commencing at 1000 nm which may be attributed to secondary doping due to conformational changes of the polymer chains. After treatment with m-cresol the film exhibited an increase of conductivity reaching ca. 100 S/cm.
