Embodiment 1
[0020] The specific steps of the graphene film non-destructive transfer method involved in this embodiment are:
[0021] (1) 1cm * 1cm or 2cm * 2cm copper foil with graphene thin film is placed flat on the glass slide, and the adhesive tape is closely attached to the copper foil surface with graphene thin film;
[0022] (2) Put the above-mentioned copper foil with adhesive tape on its surface into the ferric nitrate (Fe(NO3)3) corrosion solution with a concentration of 0.1-0.5g / ml to corrode for 2-10h, and remove the copper foil substrate to obtain the adhesive tape / graphene The film structure, the adhesion between the tape and the graphene is sufficient to make the tape a support for the graphene film;
[0023] (3) Pick up the adhesive tape / graphene film structure gently and put it into a petri dish equipped with deionized water to rinse for 10-30min, repeat this rinsing process 3-5 times; Hydrophilic treatment is carried out on the surface of the target substrate for 3-5 mi...
