Abstract:
PURPOSE: A composite for shielding an electromagnetic wave is provided to continuously maintain a shielding effect by discharging heat through a bottom layer while absorbing or shielding the electromagnetic wave from an electronic component. CONSTITUTION: An electromagnetic wave shielding layer (11) shields an electromagnetic wave. A heat conductive layer (12) is laminated on the lower surface of the electromagnetic wave shielding layer. The heat conductive layer discharges heat generated when the electromagnetic wave is absorbed. The electromagnetic wave shielding layer is made of materials which are made by adding a magnetic material and a carbon-based conductive material to a thermosetting plastic resin. The heat conductive layer is formed by adding a graphene nanoplate to the thermosetting plastic resin. [Reference numerals] (AA) Electronic component; (BB) Inside layer; (CC) Outside layer
