Studies on Multi Morphology of Polyaniline Guided by Alkali
Multi morphology of polyaniline (PANI), nanotubes, micrograins, solid and hollow spheres, were synthesized by aqueous oxidative polymerization of aniline in the presence of sodium hydroxide (NaOH), which was proposed as an alkali-guided method by the authors. By changing the molar ratio of aniline monomer to alkali, with a constant pH, the morphology can be controlled from nanotubes to micrograins, to solid spheres and to hollow spheres which were proved by SEM and TEM. The backbone structure was characterized by UV-VIS, FTIR and XRD.
