Polyaniline, a conducting polymer, is prepared by the oxidation of aniline in acid media [1]. If the polymerization is carried out in solution of strong (sulfuric) acid, a granular morphology of polyaniline is obtained [2]. In weak acids (e.g., in acetic acid) or in water, polyaniline nanotubes are produced [3]. FTIR spectra of polyaniline bases prepared in strong and weak acids differ [3,4]. The aim of the project is to find the differences in molecular structure of polyanilines and to relate them to the formation of supramolecular nanotubular morphology.
