Abstract
Embodiments of the present technology include thin coating methods for graphene and/or stanene metal composites. An example composite is created by depositing a material including any of graphene and stanene onto a porous metal foam substrate, compressing the porous metal foam the deposited material to form a graphene-metal composite, and depositing a thin metal coating on an outer surface of the porous metal foam substrate or an outer surface of deposited material using any of physical vapor deposition and chemical vapor deposition.
Claims18
A method for manufacturing a multilayered porous metal foam substrate, the method comprising:
- depositing a material comprising any of graphene and stanene onto a porous metal foam substrate;
- 3D printing thermal elastomers or metal into voids on a surface of the porous metal foam substrate;
- compressing the porous metal foam substrate and the deposited material to form a graphene-metal composite;
- and
- depositing a thin metal coating on an outer surface of the graphene-metal composite using any of physical vapor deposition and chemical vapor deposition to form the multilayered porous metal foam substrate.
A method for manufacturing a graphene-metal composite, comprising:
- depositing a layer of graphene onto a porous metal foam substrate;
- applying a layer of metal on top of the layer of graphene;
- depositing another layer of graphene onto the layer of metal;
- and
- compressing the porous metal foam substrate with the layer of graphene, the layer of metal, and another layer of graphene to form a graphene-metal composite;
- wherein the applying the layer of metal on the top of the layer of graphene and the depositing another layer of graphene onto the layer of metal is repeated until a desired number of layers is made before compressing the porous metal foam substrate.
