Synthesis of polyanilin nanocomposit by HPC as a surfactant and theeffect of MgO on the characteristics of polymer

Polyaniline has attracted considerable attention because of its unique electrical, optical and electrooptical properties and its numerous potential applications. Process ability is an important requirement in conducting polymers for their possible commercial use. Since most of the conducting polymers are notprocessable, much of the efforts made in this field have been directed towards circumventing this problem. To solve this problem, various approaches have been tried, including addition of side groups to the polymerbackbone, grafting of polymers to a non-conducting polymer and copolymerization.Polyaniline Nanocomposite (PAn) was prepared in aqueous media by polymerization of aniline using. Ammonium peroxydisulfate (APS) as anoxidant in the presence of hydroxypropyl cellulose (HPC) as surfactant. Also the effect of MgO on the characteristics of product was investigated. The results indicate that morphology, particle size, chemical structure and yield of monomer to polymer are dependent on surfactant and metallic oxide.
