Embodiment 1

[0030] A preparation method when a paper-based graphene film is applied to a flexible driver, comprising the following steps:

[0031] First, commercial printing paper, paper, was cut into rectangles with a size of 75 mm × 25 mm (length × width), and immersed in a Petri dish containing graphene oxide aqueous solution (1.5 mg / ml, 40 mL) for 5 min. After impregnation, it was placed on a glass substrate and dried by heating at 40 °C for 1 h. Then the dried paper was repeatedly immersed in the graphene oxide solution to repeat the above drying process, and after 15 dips, a paper-based graphene oxide film with an asymmetric structure was obtained.

[0032] Then, the film was further placed in a hydroiodic acid (HI) solution for 1.5 h in the dark, then washed with ethanol and water in sequence, and then placed on a heating platform at 30°C for 1 h to obtain an asymmetric paper-based graphene oxide film.

[0033] Finally, it is bonded with an adhesive polyethylene film to prepare a...
