Abstract
A graphene vapor deposition system and process are disclosed. The system includes a support for a copper-plated sheet, a housing defining an interior region, a hydraulic cylinder to move the housing between a first and a second position, a pump to evacuate the interior region, carbon powder within the interior region, and a heat source to vaporize the carbon powder, for causing graphene vapor deposition on the copper. The process includes dissolving the copper and recovering the graphene.
Claims10
A graphene vapor deposition system (10) comprising:
- a supporting surface (14) for supporting a copper-plated sheet of metal (12);
- at least one housing (20) defining an interior region (120), wherein the at least one housing (20) includes a sealing surface (22) that is capable when urged against the supporting surface (14) of maintaining predetermined vacuum conditions within the interior region (120) of the at least one housing (20);
- a hydraulic cylinder means (28) operatively coupled to the at least one housing (20) for moving the at least one housing (20) between a first position above the supporting surface (14) and a second position to urge the sealing surface against the supporting surface and provide a vacuum-tight seal therebetween;
- a pump (24) to evacuate the interior region (120) to the predetermined vacuum conditions when the sealing surface is urged against the supporting surface;
- a predetermined amount of carbon powder disposed in the interior region;
- and
- a primary heating means (16) powered by a source to convert the carbon powder to vaporized carbon, for enabling graphene vapor deposition on the copper.
4 more elements
A graphene vapor deposition process comprising:
- positioning a copper-plated sheet of metal on a surface;
- actuating hydraulic cylinder means to cause a vacuum housing defining an interior region to be lowered onto the surface, wherein the copper-plated sheet of metal is disposed within the interior region;
- initiating vacuum conditions within the interior region of the housing;
- powering on a primary heating source within the interior region;
- and
- once predetermined vacuum conditions and a predetermined temperature by the primary heating source are achieved, activating a secondary heating source.
