NOVELTY - An electromagnetic shielding film is prepared by forming electromagnetic shielding functional layer on the base layer by orderly forming the electromagnetic shielding functional particle solution with the concentration presenting gradient change. Each layer of film is prepared by atomizing process and light curing process. USE - The method for preparing electromagnetic shielding film. ADVANTAGE - The method is simple, has low equipment requirements, saves raw materials and suitable for industrialization. The product has good heat resistance, wide electromagnetic shielding band range and has good shielding effect.
