Conducting polymer has become a popular basic material for advanced applications including plastic batteries, electrochromic displays, and sensors. Polyaniline (PANI) has been extensively studied because of its environmental stability in a conducting form, easiness and low cost of synthesis, unique redox properties, and high conductivity. Nevertheless, not so many applications have been reported because conducting polymers based on PANI are not soluble in common solvent. To overcome these defects, incorporation of water-soluble side chain on PANI backbone or stabilization of PANI with polymeric stabilizer were developed. In our previous study, we reported novel water-soluble and self-doped conducting polyanline graft copolymer, namely, poly(styrenesulfonic acid-g-aniline) (PSSA-g-PANI) via chemical synthesis. Here, we reports the electrochemical synthesis of PSSA-g-PANI graft copolymer, that is, the aniline is graft copolymerized on the electrode coated with the poly(sodium styrenesulfonate-co-t-butyl carbamate-aminostyrene) (P(SSNa-co-BOC-AMS)) matrix film under cyclic potential electrolysis. The properties of resulting PSSA-g-PANI were compared with those of chemically synthesized PSSA-g-PANI. |
