Synthesis of lignosulfonic acid-doped polyaniline using transition metal ion catalysts

摘要

The present invention relates to a method of synthesizing lignosulfonic acid-doped polyaniline by oxidatively polymerizing aniline in the presence of transition metal ions selected from the group consisting of Ag(I), Fe(II), and Fe(III) salts. The present invention also relates to a method for the preparation of transition metals from transition metal salts by exposing transition metal ion containing materials to an aqueous dispersion of lignosulfonic acid-doped polyaniline.
