Abstract
A graphene heating chip includes a substrate, an insulating layer, a graphene film, and a plurality of electrodes. The substrate has two opposite a first surface and a second surface, and the substrate defines a through hole. The insulating layer is suspended on the substrate. The insulating layer covering the through hole and not in direct contact with the first surface is defined as a window, and a plurality of grooves are formed on the window. The graphene film covers the window, and the graphene film includes a first graphene film portion and a second graphene film portion, and the first graphene film portion and the second graphene film portion are spaced apart from each other. The plurality of electrodes are located on the surface of the insulating layer away from the substrate. The present application also provides a method for making the graphene heating chip.
