Oxidative Polymerization of Aniline Using Zirconium Vanadate, a Novel Polyaniline Hybrid Ion Exchanger

Electrically conductive anion-exchange polyaniline resin with diameters of 50-60 nm were prepared using zirconium vanadate as an oxidant and dopant. The polymer samples were characterized by conductivity measurements, spectral studies (FT-IR and UV-Vis absorption spectra), structural studies (X-ray diffraction), morphological studies (SEM) and thermal studies (TGA). The process of polymerization took place within 30 min and its conductivity value was 2.78 S/cm. The synthetic approach is very simple and applied in the preparation of organic-inorganic hybrid ion exchangers. (C) Koninklijke Brill NV, Leiden, 2011
