Method for preparing conductive polythiophene and conductive paper through atmospheric pressure plasma in-situ solid-state polymerization

Abstract

The invention relates to a method for preparing conductive polythiophene and conductive paper through atmospheric pressure plasma in-situ solid-state polymerization. The preparation method of the conductive polythiophene comprises the following steps: S1, fully dissolving thiophene derivatives which are in a solid state at room temperature and iodine in a volatile organic solvent, and forming a monomer film on a substrate in a spin-coating or spray-coating manner; S2, placing the monomer film obtained in S1 under atmospheric pressure plasma of a dielectric barrier discharge device for in-situsolid-state polymerization, and obtaining the conductive polythiophene film after polymerization is completed. The preparation method of the conductive paper is similar to the above preparation method, and and is characterized in that the paper needs to be soaked in a thiophene derivative and iodine solution and then subjected to in-situ solid-state polymerization under plasma. The method has theadvantages that the DBD plasma is used for triggering the solid-phase polymerization of the thiophene derivative to generate the conductive polythiophene, so that the complexity of the polymerizationprocess is reduced, and the process is simple; the thiophene derivative is subjected to solid-phase polymerization in the paper sheet to obtain the conductive paper, and the prepared conductive paperis stable in performance.
