Conducting polymers have become a popular basic material for advanced applications including plastic batteries, electrochromic displays, and sensors. However, a few applications have been reported because conducting polymers based on polyaniline exhibit poor physical and mechanical properties and are not soluble in common solvents. To overcome these defects, several methods have been reported such as the modification of monomer, copolymerization, and the composite system by blending commodity polymers with conducting polymers. In this study, a new water-soluble self-doped graft copolymer, namely, poly(styrenesulfonic acid-g-aniline) (PSSA-g-PANI) was synthesized. To obtain PSSA-g-PANI, poly(sodium styrenesulfonate-co-BOC-aminostyrene) was synthesized by copolymerizing sodium styrenesulfonate and BOC-aminostyrene monomers. Ion exchange and de-protection were conducted in acidic conditions. Aniline was grafted on the amine group of backbone polymer by chemical oxidation method and was grown to be polyaniline. PSSA-g-PANI could be dissolved in water and cast into films from their aqueous solutions. Electrical properties of synthesized graft copolymers were characterized. |
