Embodiment Construction
[0024] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as figure 1 As shown, the graphene film preparation process is as follows, a) the graphene oxide solution is prepared by the modified Hummer method, and vacuum dried; b) the graphene powder is re-infused into the deionized aqueous solution to form a neutral graphene oxide solution; c ) Prepare an A4 paper-sized glass substrate for spin-coating graphene oxide. When the graphene oxide reaches a certain thickness, the graphene oxide film is first dried at room temperature, and then placed in a 95-100° C. L-ascorbic acid solution to reduce the graphene oxide film to obtain a graphene film.
[0026] In order to obtain vertically aligned graphene films, a specific mold container needs to be designed to meet the requirements. The graphene film obtained above is first cut to an appropriate size, and then arranged in a vertical array in...
