METHOD FOR PREPARING ROD-SHAPED POLYANILINE NANOPARTICLES HAVING HIGH CONDUCTIVITY USING MICRO-EMUSION POLY-MERIZATION

摘要

A method for preparing polyaniline nanoparticles having rod shapes and high conductivity using microemulsion polymerization is disclosed. The method for preparing polyaniline nanoparticles includes the steps of adding a surfactant into a mixed solvent including water and an organic solvent, and stirring the surfactant to form a micelle, preferably at the temperature of - 30 to 0 ° C; adding aniline monomer into a reaction solution containing the micelle, and polymerizing the aniline monomer with a dopant and an oxidizing agent to form polyaniline; and adding excess organic solvent to the reaction solution to separate the polyaniline and the micelle.
