Abstract
The present disclosure pertains to an electromagnetic-wave shielding film and a preparation method thereof. The electromagnetic-wave shielding film includes a first metal layer, an insulating layer, and a second metal layer. The first metal layer has two opposite surfaces. The insulating layer is disposed on one of the surfaces of the first metal layer. The second metal layer is disposed on the other surface of the first metal layer and contains nano metal particles and an binder. The electromagnetic-wave shielding film can be used in a printed circuit board, and shows a satisfactory electromagnetic wave shielding effect.
