Embodiment 1

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

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

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

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