Description

ABSTRACT

Nanoparticles of polyaniline have been synthesized by an inverse microemulsion technique. Polymerization of aniline was confined to a nanoreactor named ‘water pool’ surrounded by surfactant molecules Tergitol and co-surfactant n –butanol in the apolar continuous phase of cyclohexane. The UV–Vis studies showed the formation of polyaniline polaron structure while FTIR showed the formation of quinoid and benzenoid structure of polyaniline. Transmission electron microscopic (TEM) studies and dynamic light scattering (DLS) studies indicated the sizes of polyaniline nanoparticles in the range 20 to 50 nm and 10 to 200 nm respectively. The conductivity of polyaniline in the form of thin films was found to be in the range of 0.5688 to 0.6335 S cm– 1.
