NOVELTY - A precursor solution comprising an inorganic gel precursor, an organic polymer gel precursor, and a solvent is treated (122) to form an inorganic wet gel comprising the organic polymer gel precursor and solvent. The inorganic wet gel is treated (124) to form a composite wet gel comprising an organic polymer network in the inorganic wet gel. The composite wet gel is dried (126) to form (120) a composite material comprising the organic polymer network and an inorganic network component.    USE - Fabrication of porous material, which is nanoporous, hierarchically porous or in form of monoliths, films, plates, coatings, powders and/or particulates (all claimed). Uses include but are not limited to thermal insulation application, gas storage application, active membranes, fuel cells, solar cells, batteries, supercapacitors, drug delivery systems, bioimplants, sensors, photonics, water purification, adsorbents, nanoreactors, nanoglues, catalysts, oxidizing agents, magnetic separation materials, chromatographic media, construction materials, solar cell components, dielectrics, sound insulation materials, culture supports, active battery components, hazard removal materials, odor elimination materials, oil spill cleanup materials, arsenic removal materials, evaporative chillers/heaters, wetting agents, human nutrient delivery materials, algae oil nanofarming materials, desiccants, proppant materials, hemostats, and template or mask used for producing other porous materials, including porous polymers and porous ceramics.    ADVANTAGE - The method enables fabrication of porous composite materials using interpenetrating inorganic-organic composite gels. The inorganic network component is free from silica or silicon-containing compounds.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the fabrication method of porous material.
