Polyaniline/Polystyrene composite was prepared in aqueous and aqueous/non aqueous media by polymerization styrene and aniline by usingammonium peroxy disulfate ((NH4)2S2O8) andpotassium iodate (KIO3) as oxidant in the presence of sodium dodecylbenzensulfonate (DBSNa) assurfactant. The composite was characterized in termsof morphology, particle size, chemical structure and glass transition temprature. The results indicate thatthe morphology and particle size of product are dependent on the surfactant and solvent media used. The chemical structure was studied by fouriertransform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and differential scanning calorimeter (DSC
