The invention provides a preparation method for a graphene film. The method comprises the following steps of carrying out ultrasonic soaking and stirring on graphene oxide, carrying out impurity filtration, coating a PET (Polyethyleneglycol Terephthalate) film with a graphene oxide solution, and carrying out carbonization and graphitization, thereby obtaining the graphene film. The method is simple in process and easy to popularize, and the obtained graphene film has extremely high shielding effectiveness and good heat dissipating performance.
