Abstract: Recently,synthesis of poly(o-ethoxyaniline)(POEA) has drown more and more attention,for the aspiration to improve the solubility and conductivity of polyaniline(PANI).POEA may be prepared with electrochemistry or chemical oxidation.In this paper,POEA is reviewed covering the emphasis technique,characterization,electric conductive mechanism and application in electric and magnetic conductive film and anrticorrosion materials.
