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 polypyrrole 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 and self-doped copolymer, namely, poly(styrenesulfonic acid-g-pyrrole) (PSSA-g-PPy) was synthesized. To obtain pyrrolylmethyl styrene (PMS), the chlorines in chloromethyl styrene (CMS) were substituted with pyrrole using potassium pyrrole. poly(styrenesulfonic acid-co-pyrrolylmethyl styrene) (PSSNa-co-PMS) was synthesized by copolymerizing sodium styrenesulfonate and PMS. To obtain PSSA-g-PPy, pyrrole was grafted onto the PSSNa-co-PMS precursor. The resulting PSSA-g-PPy was completely soluble in water or organic solvent such as DMSO. |
