プラズマ内包気泡を用いた新規PEDOT創成法の確立

抄録

Poly(3,4-ethylenedioxythiophene)(PEDOT) is known as one of the best conducting polymers and has been applied to various electronic devices. The dopants are typically used to enhance the solubility of synthesized PEDOT, however the dopants lower the conductivity of PEDOT. Then, we developed an innovative plasma enveloped bubble process to enable PEDOT synthesis with high water dispersion without introducing any dopants. The plasma polymerization process is realized in the emulsion of 3,4-ethylenedioxythiophene (EDOT) in water by plasma generated radicals inside bubbles of oxygen and argon mixture. In this study, the characteristics of plasma inside the bubbles and processed samples prepared by this innovative method were experimentally clarified. The FT-IR analysis of the synthesized sample clearly indicated the foot print of EDOT polymerization. The conductivities of the synthesized PEDOT films increased with the processing time.
