Abstract:
A process for transparently shielding a device or an enclosed area that can cause or is sensitive to electromagnetic interference, comprising at least partially surrounding the device or area with a visible light-transmissive film comprising a flexible support, an extensible visible light-transmissive continuous metal or metal alloy layer and a visible light-transmissive crosslinked polymeric protective layer, wherein the metal or metal alloy layer is coextensive with the support and when incorporated into the visible light-transmissive film can be stretched by at least 3% in an in-plane direction without loss of electrical continuity and without forming visible discontinuities in the surface of the metal or metal alloy layer as detected by the naked eye at a distance of about 0.25 meters; and connecting at least one grounding electrode to the metal or metal alloy layer.
