Objective:
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.
