Abstract
The present invention relates to a method of preparing a novel water-soluble and self-doped polyaniline graft copolymer, wherein aniline was grafted onto a poly(styrenesulfonic acid-c-aminostyrene) backbone. The graft copolymer is useful for advanced applications such as electrode manufacture, EMI shielding, static electricity dissipation, metal anti-corrosion, electrochromic materials, sensors, functional film and marine-fouling prevention.
