<p>Provided are a graphene electromagnetic wave blocking plate, a manufacturing method thereof, and a microwave oven door using the same. The manufacturing method of the graphene electromagnetic wave blocking plate comprises a step of forming a first graphene layer and a second graphene layer on the upper and lower parts of a catalyst metal layer; a step of attaching a support substrate to the lower part of the second graphene layer; a step of forming a pattern on the graphene layer and the catalyst metal layer; and a step of removing the support substrate. Therefore, the graphene electromagnetic wave blocking plate can prevent an electromagnetic wave from being emitted to the outside of a microwave oven by absorbing the electromagnetic wave through the graphene layer, forming metal patterns by patterning the catalyst metal layer, and controlling the diameter of a space between the metal patterns.</p> |
