Investigation of the Effect of DOP on Polyaniline and Polyaniline/Polystyrene Nanocomposites

Abstract

Polyaniline nanocomposite was prepared in aqueous media by polymerization of aniline using ((NH₄)₂S₂O₈) as an oxidant in the presence of dioctyl phthalate (DOP). Also polyaniline/polystyrene (PAn/PS) nanocomposite was prepared in the aqueous solution by polymerization of styrene and aniline using potassium iodate (KIO₃) and ammonium peroxy disulfate ((NH₄)₂S₂O₈) as oxidant in the presence of dioctyl phthalate (DOP). The PAn and PAn/PS nanocomposites were characterized in terms of morphology, chemical structure and glass transition temperature. The chemical structure, morphology and glass transition temperature of product were studied by Fourier Transform Infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and differential scanning calorimetry (DSC).
