Abstract

A method of forming an acid-doped polyaniline (emeraldine salt) (PANi-ES) solution including steps of: (i) mixing polyaniline (emeraldine base) (PANi-EB) with a PANi-EB solvent and a gel-inhibitor to form a gel-inhibited PANi-EB solution; (ii) removing the gel-inhibitor from the gel-inhibited PANi-EB solution to form a PANi-EB solution; and (iii) adding an acid dopant to the PANi-EB solution to form a PANi-ES solution.
