摘要:Embodiments of the present invention provide users with a system and method for manufacturing water-based hydrophobic aerogels and aerogel composites. The system and method can be carried out in a manner which is more rapid than typical ways and can be readily scalable. The method of manufacture is useful for producing water based hydrophobic aerogels and aerogel composites on a large scale with good homogeneity and consistency. Advantageously, the method of manufacture also has the benefit of a shorter processing time due to the vacuum homogenizing and mixing processes, the use of microwave assisted vacuum freeze drying for ease of synthesis of water-based hydrophobic aerogels.

摘要:The present invention relates to polysiloxane nanoparticles having the following properties: an average particle size d 50 (measured using REM recordings) in the range of 10-200 nm, a specific surface area A o of at least 50 m 2 /g, a pore volume of at least 0.2 cm 3 /g, an average pore volume d 50 of at least 0.8 nm, wherein the particles have groups that contain carbon, which groups are bonded to the silicon at least partially in the form of unsubstituted or substituted alkyl, alkenyl, aryl, arylalkyl, or alkylaryl groups. Said polysiloxane nanoparticles can be produced, among other things, in that either a silazane or a mixture of different silazanes having one or more —[Si(R)(R 1 )—NR 2 ]— units and/or a silane or a mixture of different silanes having the formula R′ x —SiX 4-a or an oligosiloxane obtainable by means of hydrolytic condensation of said silane/said silanes or a mixture of such oligosiloxanes are provided in a solvent and brought in contact with a strongly alkaline medium in such a way that the pH is not below 13 after the addition thereof. In specific embodiments, synthesis in acid is also successful.
