The present invention relates to novel water-soluble and self-doped polyaniline graft copolymer, wherein aniline was grafted onto the poly(styrenesulfonic acid-c-aminostyrene),preparation and its preparation. The water-soluble and self-doped conducting polyaniline graft copolymer of the present invention has the merit that water-soluble backbone moieties (sulfonic acid groups), which do not participate in self-doping, make the polymer soluble in water or polar organic solvent such as dimethyl sulfoxide (DMSO). The polymeric dopant (backbone poly(styrenesulfonic acid)) is so structurally stable in wide range of pH that macrophase separation by dopant migration can be prevented and doping/de-doping is reversible. The water-soluble and self-doped conducting polyaniline graft copolymer of the present invention will be useful for advanced applications such as electrode, EMI shielding, static electricity dissipation, metal anti-corrosion, electrochromic materials, sensor, functional film and marine-fouling prevention. |
