▎ 摘  要

NOVELTY - Method (m1) of forming an aerogel comprises providing a graphene oxide powder, mixing the graphene oxide powder with a solution to form an ink, using a three-dimensional (3D) printing technique to write the ink into a catalytic solution that is contained in a fluid containment member to form a wet part, curing the wet part in a sealed container for a predetermined period of time at a predetermined temperature to form a cured wet part, and drying the cured wet part to form a finished aerogel part. USE - The method is useful for forming an aerogel. ADVANTAGE - The method provides the finished aerogel part forming a multi-layer three dimensional structure or a three dimensional structure having a hierarchy of pore sizes of less than 2 nm to greater than 100 mu (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method (m2) of forming an aerogel comprising providing a graphene oxide powder, mixing the graphene oxide powder with an aqueous solution, performing a sonication operation on the mixture of the graphene oxide powder and the aqueous solution to form an ink, using a 3D printing technique to write the ink into a catalytic solution, where the catalytic solution is contained in a fluid containment member, performing the 3D printing technique to apply the ink to form many ink layers, one on top of another, to form a wet three dimensional part having a desired shape and desired dimensions, curing the wet three dimensional part in a sealed container for a predetermined period of time at a predetermined temperature to produce a cured wet three dimensional part, and supercritically drying the cured wet three dimensional part to form a finished aerogel part.
