초록 ▼

Methods and materials are described for preparing organic-inorganic hybrid gel compositions where a sulfur-containing cross-linking agent covalently links the organic and inorganic components. The gel compositions are further dried to provide porous gel compositions and aerogels. The mechanical and

대표청구항 ▼

1. A gel comprising a silica network and an organic polymer within the silica network, wherein the organic polymer is covalently bound to the silica network through a sulfur containing cross linking agent. 2. The gel of claim 1 wherein the gel is in aerogel form. 3. The gel of claim 1 or claim 2, wherein the organic polymer is selected from the group consisting of unsaturated polyesters; prepolymers based on vinylesters, acrylates, methacrylates, polyurethanes; polybutadienes; polystyrenes; polyisoprene co-polymers; styrene-butadiene copolymers; butadiene-isoprene co-polymers; butadiene-isoprene-styrene terpolymers; copolymers and terpolymers of isobutylene, para-methyl styrene and bromo-para-methyl-styrene; ethylene propylene diene monomer rubbery and a combination thereof. 4. The gel of claim 1 or 2 wherein the organic polymer is in the form of latex particles or a polymer resin. 5. The gel of claim 1 or claim 2, wherein the sulfur-containing cross linking agent is a hexasulfide compound, a tetrasulfide compound, or a disulfide compound. 6. The gel of claim 1 or claim 2, wherein the sulfur-containing cross linking agent is selected from the group consisting of polysulfide alkyl silanes, mercapto aryl silanes, polysulfide aryl silanes, silated core polysulfides, sulfur-containing silanes, sufanylsilanes, sulfur-containing siloxanes, sulfur-functional polyorganosiloxanes, and any combination thereof. 7. The gel of claim 1 or claim 2, wherein the sulfur-containing cross linking agent is a sulfidosilane of a general formula (R1—O)3—Si—R2—Sx—R2—Si—(R1—O)3 or of a general formula HS—R1—Si—(O—R2)3 where R1 and R2 are same or different alkyl or aryl groups; x is a number between 1 and 8. 8. The gel of claim 1 wherein the organic polymer in the gel is present in an amount up to 50 weight %. 9. The gel of claim 1 wherein the sulfur-containing cross linking agent in the gel is present in an amount up to 50 weight %. 10. The gel of claim 1 wherein the amount of organic polymer in the gel is at least 3 weight %. 11. The gel of claim 1 or claim 2, further comprising fibers in an amount up to 75 weight % of the gel.
