Abstract:
1. An electromagnetic shielding layer comprising a first conductive layer and a carbon nanotube film structure having a first surface and a second surface parallel and opposite to each other, the first conductive layer being disposed on the first surface of the carbon nanotube film structure and having an electrical contact with the carbon nanotube film structure, wherein the carbon nanotube film structure comprises at least one carbon nanotube film, the at least one carbon nanotube film comprises a plurality of carbon nanotubes primarily oriented along a single direction, the plurality of carbon nanotubes are parallel to the first surface of the carbon nanotube film structure, wherein the second surface of the carbon nanotube film structure is located between a surface of a electronic element and the first conductive layer to shield the electronic element from electromagnetic waves, when the electromagnetic shielding layer is in operation.
