摘要： 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. The composite material can be treated further to form a porous composite material, a porous polymer or polymer composite, a porous metal oxide, and other porous materials.

摘要： A suspension of finally divided hardened aminoplast or phenoplast resin, particularly melamine-formaldehyde resin, is prepared by mixing an aqueous solution of the resin or its precursors with a water-insoluble stabilizing agent, particularly microcrystalline cellulose; sufficient water is provided to exceed the water tolerance level of the resin and thus form a uniform emulsion or suspension of resin particles in water. Cure of the resin is then advanced such as by heating to form partially or fully cured resin particles of relatively uniform particle size.
