Abstract

The embodiment of the invention provides a transfer method of a graphene film and a base plate, relating to the technical field of display. The method can improve the phenomenon of cracking of the graphene film in the transfer process, enhances the adhesiveness of the graphene film on the target base plate, and implements transfer of the large-size graphene film. The method comprises the following steps: forming a support layer on a first substrate on which a graphene film is grown, wherein the support layer is formed on one side of the graphene film away from the first substrate; bonding the side of the first substrate with the support layer with the target base plate through a transparent adhesive layer; and removing the first substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a graphene film transfer method and a substrate. Background technique [0002] Indium tin oxide (ITO) is widely used due to its high transmittance and low square resistance, but the price of indium in ITO is expensive, and the ITO material itself is relatively brittle, resulting in the use of transparent conductive films formed by ITO. The bending resistance is poor, so it is of great significance to find a transparent conductive material with low cost and good bending resistance. [0003] Graphene has the advantages of strong bending resistance, low cost, and excellent photoelectric properties. In recent years, research on graphene films as transparent conductive materials has exploded. Graphene is usually prepared by chemical vapor deposition (CVD). During the preparation process, metal materials are generally selected as the growth substrate of graphene, and graphene must be...
