  • Electromagnetic interference shielding film having a laminated structure including a stack of metal nanoplates and a nano electrode including the same
    Patent number: 11246247
    Abstract: An electromagnetic wave shielding film includes a substrate; and an electromagnetic wave shielding layer disposed on the substrate and including a laminated structure having a planar shape and including a stack of metal nanoplates, wherein each metal nanoplate of the stack of metal nanoplates is staggered with respect to one or more other metal nanoplate of the stack of metal nanoplates so that the laminated structure has pores defined therein and between laminated structures in a stack of laminates structures. An additional embodiment of an electromagnetic wave shielding film includes an electromagnetic wave shielding layer including a composite of a polymer resin matrix composed of a polymer and at least one metal nanoplate, wherein each metal nanoplate of the at least one metal nanoplate is staggered with respect to one or more other metal nanoplate of the at least one metal nanoplate so that the composite has pores defined therein.
