    • The present invention relates to an electromagnetic wave absorbing film including graphene oxide and a manufacturing method thereof and, more specifically, to an electromagnetic wave absorbing film comprising a magnetic metal fiber; graphene oxide combined with a crystalline magnetic metal particle; and a high polymer resin in which the magnetic metal fiber and the graphene oxide are dispersed by being oriented in an in-plane direction. According to the present invention, the electromagnetic wave absorbing film includes the magnetic metal fiber for electromagnetic wave absorption and graphene oxide and thus performs more efficient electromagnetic wave absorption, compared to a film including only the electromagnetic wave absorbing film. Moreover, the graphene oxide includes the crystalline magnetic metal particle or crystalline TiO2 particle to improve the efficiency of electromagnetic wave absorption. According to the present invention, the electromagnetic wave absorbing film is applied to an electronic device to block an electromagnetic wave emitted from the device by efficiently absorbing the electromagnetic wave.

    • The present invention relates to a heat dissipation substrate made of a composite with improved interfacial adhesion and a method for manufacturing the same. The heat dissipation substrate comprises: a first ceramic layer having insulation properties; a second porous ceramic layer; and a metal layer. The first ceramic layer and the second ceramic layer are consecutively connected to each other such that interface is nonexistent. A plurality of pores on the second porous ceramic layer is impregnated with the metal layer to be combined to each other. Thus, heat dissipation properties can be enhanced with improved interfacial adhesion between the ceramic layers and the metal layer.
