Abstract:
A method for preparing functionalized polyaniline comprising the steps of:(a) providing polyaniline in a solid state form; (b) subjecting said solid state polyaniline to a redox treatment to convert backbone of said solid state polyaniline into a specified oxidation state; (c) subjecting said solid state polyaniline in an oxidation state to a reaction treatment with a solution of reactive chemical reagent(s) in a selected solvent(s) for a period of time, said solvent(s) is capable of dissolving or dispersing said chemical reagent(s) and swelling or wetting said solid state polyaniline, and said chemical reagent(s) is capable of functionalizing said solid state polyaniline and transforming the backbone of said solid state polyaniline into a more reduced form; and (d) repeating steps (b) and/or (c) as desired.
