Title:
DUAL ELECTROMAGNETIC-WAVE-SHIELDING HEATING FILM
Document Type and Number:
WIPO Patent Application WO/2023/182684
Kind Code:
A1
Abstract:
The present invention relates to a dual electromagnetic-wave-shielding heating film and, more specifically, to a dual electromagnetic-wave-shielding heating film having electromagnetic-wave-absorption layers stacked on the upper and lower surfaces of a heating sheet. This film-type planar heating element has insulation base layers formed on the respective upper and lower surfaces, and a heating layer and an electrode layer stacked between the insulation base layers and generates heat as power is applied by a power device, the film-type planar heating element comprising an electromagnetic-wave-absorption layer which is stacked in a sheet form on the upper surface and/or lower surface of the heating layer, and which is formed by mixing a nano-carbon hybrid material with a carbon paste, so that the nano-carbon hybrid material is randomly distributed, wherein the heating layer has a thickness of 1-50 μm and an adhesive strength of 50 N or more with the electromagnetic-wave-absorption layer.
