Publication number: 20220298321Abstract: Porous three-dimensional networks of polyurea and porous three-dimensional networks of carbon and methods of their manufacture are described. In an example, polyurea aerogels are prepared by mixing an triisocyanate with water and a triethylamine to form a sol-gel material and supercritically drying the sol-gel material to form the polyurea aerogel. Subjecting the polyurea aerogel to a step of pyrolysis may result in a three dimensional network having a carbon skeleton, yielding a carbon aerogel. The density and morphology of polyurea aerogels can be controlled by varying the amount of isocyanate monomer in the initial reaction mixture. A lower density in the aerogel gives rise to a fibrous morphology, whereas a greater density in the aerogel results in a particulate morphology. Polyurea aerogels described herein may also exhibit a reduced flammability.Type: ApplicationFiled: November 1, 2021Publication date: September 22, 2022Applicant: Aerogel Technologies, LLCInventors: Nicholas Leventis, Chariklia Sotiriou-Leventis, Sudhir Mulik

Publication number: 20220153951Abstract: Systems and methods for producing aerogel materials are generally described. In certain cases, the methods do not require supercritical drying as part of the manufacturing process. In some cases, certain combinations of materials, solvents, and/or processing steps may be synergistically employed so as to enable manufacture of large (e.g., meter-scale), substantially crack free, and/or mechanically strong aerogel materials.Type: ApplicationFiled: June 23, 2021Publication date: May 19, 2022Applicant: Aerogel Technologies, LLCInventors: Stephen A.

Publication number: 20220127148Abstract: Three-dimensional nanoporous aerogels and suitable preparation methods are provided. Nanoporous aerogels may include a carbide material such as a silicon carbide, a metal carbide, or a metalloid carbide. Elemental (e.g., metallic or metalloid) aerogels may also be produced. In some embodiments, a cross-linked aerogel having a conformal coating on a sol-gel material is processed to form a carbide aerogel, metal aerogel, or metalloid aerogel. A three-dimensional nanoporous network may include a free radical initiator that reacts with a cross-linking agent to form the cross-linked aerogel. The cross-linked aerogel may be chemically aromatized and chemically carbonized to form a carbon-coated aerogel. The carbon-coated aerogel may be suitably processed to undergo a carbothermal reduction, yielding an aerogel where oxygen is chemically extracted. Residual carbon remaining on the surface of the aerogel may be removed via an appropriate cleaning treatment.Type: ApplicationFiled: January 7, 2022Publication date: April 28, 2022Applicant: Aerogel Technologies, LLCInventors: Nicholas Leventis, Anand G.

Publication number: 20210206940Abstract: Nanoporous three-dimensional networks of polyurethane particles, e.g., polyurethane aerogels, and methods of preparation are presented herein. Such nanoporous networks may include polyurethane particles made up of linked polyisocyanate and polyol monomers. In some cases, greater than about 95% of the linkages between the polyisocyanate monomers and the polyol monomers are urethane linkages. To prepare such networks, a mixture including polyisocyanate monomers (e.g., diisocyanates, triisocyanates), polyol monomers (diols, triols), and a solvent is provided. The polyisocyanate and polyol monomers may be aliphatic or aromatic. A polyurethane catalyst is added to the mixture causing formation of linkages between the polyisocyanate monomers and the polyol monomers. Phase separation of particles from the reaction medium can be controlled to enable formation of polyurethane networks with desirable nanomorphologies, specific surface area, and mechanical properties.Type: ApplicationFiled: September 25, 2020Publication date: July 8, 2021Applicant: Aerogel Technologies, LLCInventors: Nicholas Leventis, Chariklia Sotiriou-Leventis, Chakkaravarthy Chidambareswarapattar

Publication number: 20200239319Abstract: Porous three-dimensional networks of polyimide and porous three-dimensional networks of carbon and methods of their manufacture are described. For example, polyimide aerogels are prepared by mixing a dianhydride and a diisocyanate in a solvent comprising a pyrrolidone and acetonitrile at room temperature to form a sol-gel material and supercritically drying the sol-gel material to form the polyimide aerogel. Porous three-dimensional polyimide networks, such as polyimide aerogels, may also exhibit a fibrous morphology. Having a porous three-dimensional polyimide network undergo an additional step of pyrolysis may result in the three dimensional network being converted to a purely carbon skeleton, yielding a porous three-dimensional carbon network. The carbon network, having been derived from a fibrous polyimide network, may also exhibit a fibrous morphology.Type: ApplicationFiled: September 6, 2019Publication date: July 30, 2020Applicant: Aerogel Technologies, LLCInventors: Nicholas Leventis, Chariklia Sotiriou-Leventis, Chakkaravarthy Chidambareswarapattar
