Abstract: 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.

Abstract: Film, fibre, foam and adhesive materials are produced from soluble S-sulfonated keratins. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. Treatments used include removal of the S-sulfonate group by treatment with a reducing agent, treatment with an acid or treatment with a common protein crosslinking agent or treatment with a reduced form of keratin or keratin protein. The films are made by solvent casting a solution of S-sulfonated keratin proteins, the foam made by freeze-drying a solution of S-sulfonated keratin proteins and the fibres made by extruding a solution of a S-sulfonated keratin protein.

Abstract: The present disclosure provides an aerogel formed of a tannin-containing porous material including a polymeric material, a tannin, and a clay. In some embodiments, the tannin-containing porous material is produced by forming an aerogel precursor including a polymeric material, a tannin, and a liquid dispersion medium; freezing the aerogel precursor; and freeze drying. In other embodiments, the tannin-containing porous material is produced by coating a formed porous aerogel material with a tannin-containing coating solution including tannin dispersed therein. The aerogel provides a flame retardant material having improved mechanical properties.
