This technology offer is technique that can turn renewable cellulose paper feedstock into lightweight carbon foams that are architected into highly complex geometries that cannot be produced through traditional manufacturing techniques, such as closed-cell lattices. These carbon foam lattices exhibited excellent mechanical properties, particularly in energy absorption, as well as good battery characteristics, low thermal conductivity and relatively good electrical conductivity. Unlike most traditional carbon foams that are brittle, paper-based carbon foams can withstand ~ 30% strain before significant deformation sets in. These multifunctional properties, the quick and easy customization of part geometry and the use of green feedstock are expected to be useful for aerospace, automobile, sports, medical and thermal insulation markets, as they search for the next generation of eco-friendly, high-performance materials.This technology is available for R&D collaboration, IP licensing, or test bedding, with partners such as battery manufacturers, supplier to battery manufacturer, space industry, etc.
The potential applications are as follow: Thermal Insulation Fire-proofing Refractory Material Composite Parts Rocket Nozzles Acoustic Tile EMI Shielding Water and Gas Filters Li-Battery Anodes, Aerospace Materials
Market Trends and Opportunities
Material is multifunctional and covers several markets, including but not limited to aerospace, automobile, carbon foam batteries, insulation etc. The structural carbon market is ~ USD$4 billion in the US alone. The primary differentiator in this technology is that it uses cellulose paper, a freely available and renewable green resource rather than fossil fuel as a precursor. Next, the technology enables the carbon foams to be additively manufactured into prescribed geometries. Customization of geometry is therefore easy, quick and cheap and machining is not needed.
Feedstock is a green, cheap, renewable material – cellulose paper Easy customization of carbon foam geometry with quick turnaround time Thermal, electrical, mechanical and battery performance are in the range of the best performing carbon foams on the market
