Claim Text:
1. A method comprising: treating a precursor solution comprising an inorganic gel precursor, an organic polymer gel precursor, and a solvent to form an inorganic wet gel comprising an inorganic gel network, the organic polymer gel precursor, and the solvent, wherein the inorganic gel network comprises a metal oxide, a hydrous metal oxide, a metal hydroxide, or a combination thereof; treating the inorganic wet gel to form an interpenetrating inorganic-organic composite wet gel comprising an organic polymer network in the inorganic wet gel, wherein treating the inorganic wet gel comprises polymerizing the organic polymer gel precursor to form the organic polymer network in the inorganic wet gel, and wherein the inorganic gel network and the organic polymer network interpenetrate each other; and drying the composite wet gel to form a composite material comprising the organic polymer network and an inorganic network component comprising the metal oxide, the hydrous metal oxide, the metal hydroxide, or a combination thereof.
