Rapid preparation method of paper-based flexible transparent electrode based on silver nanowires and PEDOT

Abstract

The present invention discloses a rapid preparation method of a paper-based flexible transparent electrode based on silver nanowires and PEDOT, belonging to the nanometer photoelectric material technology field. The method comprises: dissolving a certain amount of linters into pre-cooling urea solution to form viscose solution and then form film of cement gel after film curing, and preparing transparent paper after drying of the film of cement gel; and uniformly performing spin coating of the silver nanowires on the surface of the transparent paper, performing spin coating of the PEDOT at the surface of the silver nanowires, and finally forming a final paper-based flexible transparent electrode after the silver nanowires with the PEDOT are thoroughly dried. The flexible transparent electrode provided by the invention is simple to operate and low in cost, is degradable and is wide in application range. The method is rapid and simple and can perform large-area preparation, and the prepared paper-based flexible transparent electrode is flexible, foldable and stable in electrical property.

Description
