Patent number: 9862644Abstract: A product formed from a first material including a geopolymer resin material, a geopolymer material, or a combination thereof by contacting the first material with a fluid and removing at least some of the fluid to yield a product. The first material may be formed by heating and/or aging an initial geopolymer resin material to yield the first material before contacting the first material with the fluid. In some cases, contacting the first material with the fluid breaks up or disintegrates the first material (e.g., in response to contact with the fluid and in the absence of external mechanical stress), thereby forming particles having an external dimension in a range between 1 nm and 2 cm.Type: GrantFiled: February 19, 2016Date of Patent: January 9, 2018Assignee: ARIZONA BOARD OF REGENTS, A BODY CORPORATE OF THE STATE OF ARIZONA ACTING FOR AND ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Dong-Kyun Seo, Dinesh Medpelli, Danielle Ladd, Milad Mesgar

Patent number: 9365691Abstract: Porous materials are fabricated using interpenetrating inorganic-organic composite gels. A mixture or precursor solution including an inorganic gel precursor, an organic polymer gel precursor, and a solvent is treated to form an inorganic wet gel including the organic polymer gel precursor and the solvent. The inorganic wet gel is then treated to form a composite wet gel including an organic polymer network in the body of the inorganic wet gel, producing an interpenetrating inorganic-organic composite gel. The composite wet gel is dried to form a composite material including the organic polymer network and an inorganic network component.

Patent number: 9308511Abstract: Methods, apparatuses, and systems for fabricating porous materials using thixotropic gels. A shear force is applied to a thixotropic material causing the material to flow. Multiple components are added to the thixotropic material while applying the shear force causing the multiple components to be distributed in the material. The shear force is removed such that the static properties of the thixotropic material in the absence of the shear force retain a distribution of the multiple components in the thixotropic material to form a composite gel material that includes liquid within a network of inter-connected solid particles that include the distributed plurality of components. The liquid in the composite gel material is removed to form a porous composite material.Type: GrantFiled: October 12, 2010Date of Patent: April 12, 2016Assignee: ARIZONA BOARD OF REGENTS, A BODY CORPORATE OF THE STATE OF ARIZONA ACTING FOR AND ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Dong-Kyun Seo, Alex Volosin
