Intrinsically hydrophobic silica-based aerogel composition preparation method
A recently granted patent (Publication Number: US11912579B2) discloses a method for producing a silica-based aerogel composition that is intrinsically hydrophobic without the need for surface modification with a hydrophobizing agent. The method involves providing a precursor solution containing silica gel precursor materials and a solvent, with over 30% of at least one silica gel precursor material being an alkylsilane with a single alkyl group attached to silicon. A basic catalyst solution, specifically guanidine hydroxide, is then added to facilitate the transition of the precursor materials into a gel composition. The resulting gel is processed to extract the solvent, yielding the hydrophobic silica-based aerogel composition.
Furthermore, the patent claims encompass the incorporation of reinforcement materials and additives into the silica-based aerogel composition. Additives, present in varying percentages, can include a wide range of materials such as boron carbide, titanium oxide, iron oxide, and various clays like kaolinite and montmorillonite. These additives can enhance specific properties of the aerogel composition, with the patent detailing the permissible range of inclusion for optimal results. By offering a detailed method for producing hydrophobic silica-based aerogels and allowing for the incorporation of diverse additives, this patent opens up possibilities for the development of advanced materials with tailored characteristics for various applications.
