NOVELTY - A thin film material is comprises 0.5-10% silver graphene composite on thermoplastic base material. The mass ratio of graphene oxide and silver in silver-loaded graphene composite is 1:2-4. USE - Thin film material is used for packing. ADVANTAGE - The thin film material has high antibacterial and antistatic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of thin film material. 10 mg Dispersing graphite oxide is added to 10 mL deionized water at room temperature and ultrasonically-dispersed, to form uniform graphene oxide solution. Then, silver nitrate solution, aqueous ammonia solution and formic acid solution are added to mixture, heating under water bath condition, stirred uniformly, allowed to standstill at room temperature, reacted for 2 hours, centrifuged, washed and dried, to obtain thin film material.
