Abstract
Water dispersible composites of poly(N-vinylcarbazole) (PNVC), polypyrrole (PPY) and polyaniline (PANI) with colloidal MnO2 were prepared. The incorpo ration of the polymers in the composites was endorsed by FTIR studies. SEM analyses revealed distinct morphological features of the composites. TEM an alyses confirmed particle sizes to be in the nanometer range. DC conductivi ties of the PNVC-MnO2 composites were 10(7) to 10(10) fold improved relativ e to the base polymer while those for PPY-MnO2 or PANI-MnO2 composites incr eased with the increasing polymer loading and dopant amount.
