摘要

[Objective] This paper was to introduce the chemical oxidative synthesis process, properties and test methods of 3,4-ethylenedioxythiophene(EDOT). [Method] The poor water solubility of EDOT was solved by using polyethylene glycol 20000(PEG) as the surfactant. The monomer was polymerized by chemical oxidative synthesis. The product was analyzed and verified by infrared spectrum, X-ray diffraction, ultraviolet-visible absorption spectra.[Result] The conductivity of the product was the best when the mass ratio of PEG and EDOT was 1∶1. The effects of oxidant dose and reaction time on the conductivity and yield of the product showed certain regularity. [Conclusion] EDOT could be polymerized by PEG and FeCl3, and the polymerization product was PEDOT.
