Abstract
A method for producing a conductive polyaniline/layered inorganic nanocomposite having a conductivity greater than 10.sup.-1 S/cm is disclosed. The method comprises the steps of: (a) forming a reaction mixture comprising water, an aniline monomer, a protonic acid, an oxidizing agent, and a layered silicate which has been subjected to an acid treatment or is intercalated with polyethylene glycol; and (b) subjecting said reaction mixture to oxidative polymerization to form a conductive polymeric nanocomposite having said layered silicate dispersed in a polymeric matrix of polyaniline.
