The present invention includes methods of manufacturing a metal infused graphitic material. Also described is how this device may be rendered impermeable. The present invention includes the electroplating/electroless deposition of metal on exposed internal and external surfaces of a porous graphitic substrate. The deposition of metal on the internal structure is accomplished by replacing the void space in the porous substrate with an electrolyte solution containing dissolved metallic species. The plating is initiated either through electrochemical means, electroless means, chemical vapor deposition means, or other means obvious to one familiar in the art of metal plating. A post-deposition bath is also described wherein the plating may be removed from one or both sides of the external surface without impacting the internal pore plating.

Disclosed is an anisotropic thermal interface pad structure for increasing heat conductivity between heat spreader and heat source of an electronic device. The anisotropic thermal interface pad structure includes an anisotropic thermally conductive film and a carrier polymer material for holding the anisotropic thermally conductive film. The anisotropic thermally conductive film fills the air gap between the heat spreader and the heat source. The anisotropic thermally conductive film is configured in zig-zag layers structure to achieve high thermal conductivity throughout the components of the electronic device. Further, each layer of the zig-zag structure of anisotropic film is perforated to achieve inter-connection. The inter-connection improves the compression ratio of the anisotropic film.
摘要:
Functional components of spacecraft structures can be subject to detrimental impacts by energetic particles produced from an electric propulsion system. A graphene coating applied to a functional component can maintain electrical conductivity upon a surface of the functional component, thereby allowing charge dissipation to take place, while also resisting sputtering erosion resulting from impacts of the energetic particles. Accordingly, spacecraft structures can include an electric propulsion system, a functional component that is at least partially impacted by an outflow of the electric propulsion system, and a graphene coating upon the functional component. Methods for operating such spacecraft structures can include generating an outflow of energetic particles from an electric propulsion system of a spacecraft structure, and at least partially impacting the outflow of energetic particles upon a functional component of the spacecraft structure, where the functional component has a graphene coating thereon.
摘要:
A method of forming an polymer composites is disclosed herein that includes infiltrating CNT sponges with a polymer or metal to form a composite. The method uses a relatively easy, scalable, and low-cost synthesis process that makes the composites attractive as TIM. CNTs in the sponge structure are covalently bonded, resulting in a low Young's modulus while at the same time maintaining a good thermal conductivity. This strategy makes it possible to obtain both high deformability and high thermal conductivity, which are difficult to have simultaneously due to their adverse correlation.
摘要:
A thermal energy storage module is provided comprising a plurality of spaced thermal energy storage panels separated by heater assemblies. Each thermal energy storage panel comprises a graphite core, a substantially gas tight housing encasing the graphite core, and a heat exchanger comprising 'heat exchanger tubing. The heat exchanger tubing includes a heat exchanger inlet and a heat exchanger outlet. The heat exchanger tubing is at least partially embedded in the graphite core, with the heat exchanger inlet and the heat exchanger outlet extending through the housing. The housing is sealed around the heat exchanger inlet and the heat exchanger outlet. A method of controlling the thermal energy storage module comprises: establishing an electrical connection between the heater assemblies and a supply of electrical power whereby the heater assemblies heat the thermal energy storage panels; monitoring a temperature in the graphite core of each thermal energy storage panel; and when any graphite core attains a temperature greater than a predetermined limit, disconnecting the heater assemblies adjacent to the given thermal energy storage panel from the supply of electrical power.
