- Аннотация: Polythiophene and its derivatives have been at the center of considerable scientific interest for their attractive and superior chemical and physical properties [1]. Among the derivatives of polythiophene, poly(3,4-ethylenedioxythiophene) (PEDOT), is one of the most successful conducting polymers because of its low bandgap, excellent environmental stability, high electrical conductivity, and transparency in thin oxidized films. Since PEDOT was first synthesized in 1989, many studies on PEDOT have been carried out. Many applications have been reported for solid electrolytic capacitors, antielectrostatic agents, transparent electrodes in light emitting diodes, and underlayers for the metallization of printed circuit boards. Numerous researches have been made on the syntheses of PEDOTh by the electrochemical and chemical oxidative polymerizations and organic synthesis of 3,4-ethylenedioxythiophene (EDOT) [2-4], and the latter is more suitable for mass production. Only several years ago a new technique of polythiophene synthesis was suggested by Japanese scientists [5]. It consists of high-concentration emulsion polymerization of ethylenedioxythiophene (EDOT) in the presence of sodium salt of 2-naphthalenesulfonic acid (2-NaNS) as dopant and ferrum sulfate as oxidant. The conductivity of obtained by this method PEDOT was 160 Siemens per centimeter. In present article we developed a route for the increase of PEDOT conductivity from 100 S/cm to several thousands.
