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.

Sulfur-linked hybrid gel compositions and aerogels thereof

A coating composition may include one or more radiation-curable resins having reactive groups in a hydrophilic region, a reactive surfactant comprising a reactive moiety; and a photoinitiator, wherein, upon the exposure of the photoinitiator to light energy, the one or more radiation-curable resins are cured to form a hydrophilic network with the reactive surfactant being bound to the network by binding of the reactive moiety of the surfactant to the reactive groups of the one or more radiation-curable resins. The cured coatings provide long lasting, washable, anti-fog properties.

Fog resistant coatings

Sulfur-containing organic-inorganic hybrid gel compositions and aerogels

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&#x2014;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.

Modified hybrid silica aerogels

Disclosed herein are stable organosiloxane coating compositions comprising a blocked isocyanate silane and at least one polyol that provide abrasion resistant coatings for transparent polymer substrates. The cured coatings also have excellent adhesion to the polymer substrates. In accordance with certain embodiments, the disclosed coating compositions, which when cured on the substrate, provide formable, weatherable, anti-fog, or combinations of formable, weatherable, or anti-fog organosiloxane coatings. Also disclosed herein are articles comprising coatings cured from such coating compositions, and processes for making the coating compositions.
