Synthesis and Characterization of Nanocomposite of Multi-Walled Carbon Nanotube and Polyaniline Nanoparticle

Abstract

We synthesized multi-walled carbon nanotube(MWNT)/polyaniline(PANI)nanocomposites from an oxidative dispersion polymerization using poly(vinyl alcohol)(PVA)as a polymeric stabilizer. Purified MWNT whose metallic catalysts have been removed in acidic media was applied. The formation of nanocomposites and their morphology were confirmed by both scanning electron microscopy(SEM)and transmission electron microscopy(TEM). Electrorheological properties were further characterized by a rotational rheometer equipped with a high voltage generator.
