NOVELTY - An electromagnetic wave shielding film is obtained by applying electromagnetic wave shielding slurry on the transparent substrate. The slurry comprises 0.1-10 %mass silver nanowires, 0.05-0.1 %mass poly(3,4-ethylenedioxythiophene)polystyrene sulfonate, 0.01-0.1 %mass graphene, 10-20 %mass aqueous acrylic resin, 10-20 %mass aqueous polyurethane resin, 0.01-1 %mass hardener, 0.01-1 %mass small molecule dispersant, 0.01-1 %mass leveling agent, 0.01-1 %mass defoamer and water. USE - Electromagnetic wave shielding film (claimed). ADVANTAGE - The electromagnetic wave shielding film has visible light transmittance of 90% or more, and strong shielding efficiency in large frequency range.
