A hydrophobic airgel comprising a low occupancy mono-functional unit

摘要

The problem to be solved by the present invention is to provide a composition which exhibits as high a permanent hydrophobicity as possible and which exhibits a low flammability, i.e. a low carbon content as low as possible, while at the same time exhibiting a low hardness and brittleness than known systems, Stability, that is, a high mechanical load-carrying capacity. The present invention is synthesized from an oxidic unit and an [R _x SiO _{(4-x) / 2} ] unit wherein the primary particles have a composition of [R _x SiO _{(4-x) / 2} ] units Wherein x may be the same or different and is 1 or 2, R may be the same or different and is hydrogen or a substituted or unsubstituted or unsubstituted, where the oxide unit is [SiO _4/2] to solve the aforementioned problems by, providing a gel or Rio process for producing a gel, and it is selected from the airgel containing unit. The gels provided can be used in cosmetics, medical or chromatographic applications, and as catalysts or catalyst supports. If the gel is an aerogel, it is preferably used for thermal insulation and / or sound insulation.
