Abstract: Conducting polymers based on renewable resource materials are very attractive because of their wide availability and lower cost compared to petroleum based products. Here we developed a novel dopant for electrically conducting polyaniline from renewable resource cardanol, the main component of cashew nut shell liquid (CNSL). The novel dopant 2-?-unsaturated-4-hydroxy-4?-sulfinic acid azo benzene or otherwise known as cardanol azo sulfonic acid (1) is synthesized by reaction of diazotized sulphanilic acid (4-aminophenylsulfonicacid) with cardanol under the basic condition. The new cardanol azo sulfonic acid (1) has a long alkyl chains at the 2 positions, which increases the solubility of the dopant as well as polyaniline doped materials in common solvents for many applications.
