Water dispersible conducting nanocomposites of poly(N-vinylcarbazole), polypyrrole and polyaniline with nanodimensional manganese (IV) oxide

Water dispersible composites of poly(N-vinylcarbazole) (PNVC), polypyrrole (PPY) and polyaniline (PANI) with colloidal MnO₂ were prepared. The incorporation of the polymers in the composites was endorsed by FTIR studies. SEM analyses revealed distinct morphological features of the composites. TEM analyses confirmed particle sizes to be in the nanometer range. DC conductivities of the PNVC–MnO₂ composites were 10⁷ to 10¹⁰ fold improved relative to the base polymer while those for PPY–MnO₂ or PANI–MnO₂ composites increased with the increasing polymer loading and dopant amount.
