▎ 摘  要

NOVELTY - Manufacturing transparent electromagnetic shielding film involves coating conductive nanowires that shield and absorb electromagnetic waves on the flexible substrate, coating a solution containing graphene oxide or reduced graphene oxide on the flexible substrate on which the conductive nanowires which are formed, evaporating the solvent contained in the solution using a wet sintering process and coating the graphene oxide or reduced graphene oxide on the surface of the sintered conductive nanowires, and forming a water repellent layer on the graphene oxide or reduced graphene oxide. The sintered conductive nanowires have a transmittance of 80% or more, having a shielding performance of 30dB or more. USE - Method for manufacturing transparent electromagnetic shielding film. ADVANTAGE - The method enables to manufacture transparent electromagnetic shielding film that has excellent electromagnetic shielding performance, excellent flexibility and durability.
