Manufacture of reticulated vitreous carbon (RVC) foams with variable density

Description
Reticulated vitreous carbon (RVC) foam is the material with high porosity and hydraulic permeability, high electric and thermal conductivity, high specific mechanical strength and modulus, low density, low thermal expansion, excellent resistance to many corrosive media, and high operating temperatures of about 3000 C in non-oxidizing environments.[br][/br][br][/br]RVC foam is known to be a promising material in many applications, such as flow-through electrodes in electrochemical processes, bio-scaffolds for the bone defect repair, current collectors in the redox flow batteries, field emission cathodes, heat sink components for thermal management, catalyst supports in electrocatalytic processes, super lightweight aerospace materials, effective electromagnetic shields and filters.[br][/br][br][/br]The offered RVC foam manufacturing process comprises the following steps:[br][/br]- impregnation of a reticulated polyurethane foam template with a setting precursor resin[br][/br]- squeezing away the excess resin[br][/br]- setting the resin and its pyrolysis in an inert atmosphere at temperatures of above 1000 C.[br][/br]Alternative route is based on impregnation of a bed of soluble granules (sacrificial template) with a precursor resin followed by setting, leaching away the granules and pyrolysis.[br][/br][br][/br]Compared to the existing technologies, the offered one can ensure RVC foams with tunable density and, hence, variable mechanical strength, electric and heat conductivity. A graded microstructure and composition of the foam's structural components, including the surface functionalization or formation of sub-layers for the further deposition of active layers can be created.[br][/br][br][/br]The collaboration can be based on the Research cooperation agreement or Technical cooperation agreement. The client activities are targeted at the development of new materials and processes, and the technology transfer or implementation at own manufacturing facilities. The cooperation agreement mechanism are preferable for joint R&D activities, technology upscaling and its transfer to third parties.[br][/br]
