摘要:
Disclosed and claimed herein are hybrid silica aerogels containing non-polymeric, functional organic materials covalently bonded at one or both ends to the silica network of the aerogels through a C—Si bond between a carbon atom of the organic material and a silicon atom of the aerogel network. Methods of their preparation are also disclosed.

摘要:
The present invention provides methods and systems to effectively insulate hot or cold surfaces in industrial, domestic and building systems. It provides composite thermal insulation systems, which comprises an at least two-layer thermal insulation cladding, with at least two layers each containing from 25 to 95% by weight of aerogel and from 5 to 75% by weight of inorganic fibres, wherein the layers of the thermal insulation cladding are joined to one another by means of an inorganic binder.
摘要:
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 thermal properties of the dried gel compositions are also disclosed.
