NOVELTY - Coating agent coated protective film produced by dissolving metal nanoparticles, graphene or graphene quantum dots in solvent, and coating the obtained solution on the protective film, is claimed. The protective film is applied to an entire surface of a terminal by applying an adhesive layer on the entire surface. USE - The film is useful for mobile phone. ADVANTAGE - The film disperses self heat of mobile phone, prevents heat transfer and electromagnetic waves, and reduces fatigue of eyes.
