Abstract: Morphology of polyaniline was tunable during in situ oxidative polymerization of the monomer aniline simply by changing pH values within the alkaline region, which could be regulated from tubular to spherical shapes with pH being increased. UV-Vis and FTIR spectra were used to characterize the molecular structures of the assembled samples, which was responsible for the lower electrical conductivity.

Key words: Polyaniline, pH, Morphology
