Abstract

Polyaniline (PANI) nanocomposite has been successfully prepared in aqueous
media by the chemical polymerization of aniline with ammonium peroxydisulphate
as an initiator in the presence of a steric stabilizer such as sodium dodecylbenzenesulfonate
(DBSNa), Poly(vinyl pyrrolidone) (PVP), poly(vinyl alcohol)
(PVA), poly(ethylene glycol) (PEG) and hydroxypropylcellulose (HPC). The
chemical structure, morphology, thermal stability and thermal degradation of the
synthesized PANI nanocomposite were studied by different techniques such as
fourier transform infrared spectroscopy (FTIR), scanning electron microscope
(SEM), X-ray diffraction (XRD) and four-probe. The results revealed that surfactant
dispersed uniformly in polyanilin matrix and made a nanocomposite with
average crystallite size about 74 nm.
