Abstract

The invention discloses a rapid transfer method based on a graphene adhesive tape. The method comprises the following steps: preparing an adhesive tape solution to form an adhesive tape film; obtaining a graphene film; pasting the working surface of the film adhesive tape on the graphene film to obtain a graphene adhesive tape; floating the graphene adhesive tape on the surface of deionized water,and cleaning 2-3 times; cleaning the surface of a required target substrate, and preparing to transfer graphene; taking out the graphene adhesive tape from the deionized water, placing the graphene adhesive tape on the target substrate, enabling the graphene adhesive tape to be completely attached to the target substrate, and enabling the graphene to be in contact with the target substrate; placing the graphene adhesive tape and the target substrate under an infrared baking lamp, and heating to soften the graphene adhesive tape; and after the moisture is completely evaporated, slowly tearingoff the adhesive tape to finish graphene transfer from the adhesive tape to the target substrate. The method has the advantages of low dependence on professional equipment, simple transfer process andcapability of completely transferring the graphene and storing the graphene for a long time.

Description

technical field [0001] The invention belongs to the field of graphene transfer, in particular to a graphene flexible adhesive tape and a method for rapidly transferring graphene based on the adhesive tape. Background technique [0002] The traditional graphene transfer technology is a wet transfer technology. The specific transfer process is as follows: 1. Drop a small amount of polymethyl methacrylate (PMMA) on the graphene / copper foil / graphene side, and rotate at a high speed to form a thin film. Form PMMA / graphene / copper foil / graphene to avoid damage to graphene during transfer; 2. Heat PMMA / graphene / copper foil / graphene at high temperature to solidify PMMA; 3. Use oxygen plasma cleaner Remove the graphene on the back to obtain PMMA / graphene / copper foil, avoiding the influence of graphene on the back on the transfer result; 4. Float the PMMA / graphene / copper foil on the surface of the etching solution, etch the copper substrate to obtain PMMA / graphene 5. Repeatedly wash t...
