Synthesis of soluble conducting polymers by acoustic mixing

DWPI Title: Formation of polyaniline used as conducting polymer for e.g. microelectronic devices, involves combining aniline monomer, oxidant, water and organic solvent, subjecting to acoustic mixing to form emulsion and recovering polyaniline
Abstract: A method including combining an aniline monomer, an oxidant, water and an organic solvent; subjecting the combination to acoustic mixing to form an emulsion; and recovering a polyaniliine from the combination. A method including combining a aniline monomer, an oxidant, water and an organic solvent; forming a polyaniline by acoustic mixing the combination; and recovering the polyaniliine from the combination. A method including forming a combination of an aniline monomer, an oxidant, water and an organic solvent in the absence of an emulsifier; acoustic mixing the combination for a time period to form a polyaniline; and recovering a polyaniliine from the combination.
Use: Formation of polyaniline used as conducting polymer used in microelectronic devices, photovoltaics, batteries, fuel cells and sensors. Uses include but are not limited to anti-static and electrostatic dissipation coatings, electromagnetic interference shielding, anti-corrosive coating, hole injection layers, transport conductors, actuators, indium tin oxide replacements and electrochromic coatings.
Advantage: The method efficiently produces polyaniline having excellent conductivity even without using an emulsifier.
Novelty: Formation of polyaniline involves (110) combining aniline monomer, an oxidant, water and organic solvent to form mixture, (120) subjecting the mixture to acoustic mixing at frequency of 15-2000 Hz to form an emulsion and (140) recovering polyaniline from the mixture.
