Layered Bronsted acids, HMMoO6. H2O (M = Nb, Ta) possessing a rutile-related structure, readily intercalates aniline giving (C6H5NH3)(x)H1-xMMoO6. H2O (x similar to 0.35). Oxidation of the latter in air at 130 degrees C polymerizes the interlayer aniline to give (PANI)(x)H1-xMMoO6 nanocomposites (PANI = polyaniline). Characterization of the composites by various physical methods reveals that the polymerization is near-quantitative, occurring within the galleries of the inorganic host. EPR spectroscopy shows a single resonance at g = 2.003 which is characteristic of PANI, indicating that the inorganic host does not participate in the oxidative polymerization of aniline.
