Problems solved by technology

However, in actual operation, the adhesion ability of graphene sheets to transparent substrates is limited, and the stacking effect is indirectly improved by the size and number of layers of graphene sheets, which is not ideal for the improvement of electrical conductivity.

Abstract

A graphene transparent conductive film, Which includes a plurality of graphene sheets and a transparent conductive binder binding the graphene sheets to form the graphene transparent conductive film. The weight ratio of the graphene sheets to the transparent conductive binder is within a range of 0.01 to 1 wt %, and the volume percentage of the transparent conductive binder in the graphene transparent conductive film is within a range of 0.5 to 10%. The transparent conductive binder is a transparent conductive polymer comprising at least one structure of polythiophene and polycationic polymer. The graphene sheets are stacked and bound together by the transparent conductive binder to form the integrated conductive network structure such that the resulting graphene transparent conductive film still has lower sheet resistance with high transparency. Therefore, the present invention can be formed on the flexible support body and greatly expand the field of application.

Description

technical field [0001] The invention relates to a transparent conductive film, especially a transparent conductive film containing graphene. Background technique [0002] The transparent conductive films commonly used in the prior art are mainly metal thin films and metal oxide thin films. Among metal oxides, Indium Tin Oxide (ITO) is widely used, has good optical and electrical properties, and its preparation technology has reached maturity. [0003] US patent US7294852B2 discloses a preparation method of indium tin oxide thin film. Indium oxide and tin oxide are deposited on the substrate with external bias by sputtering, and the indium tin oxide thin film can be affected by adjusting the flow rate of oxygen and deposition bias. resistance or other electrical properties. The resistivity of the indium tin oxide film prepared by this preparation method is less than 10 -3 Ω·cm. [0004] US Patent No. 7309405B2 discloses a method for preparing an indium tin oxide thin film...
