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.

The compounds are then fluorinated. To prepare the polysiloxanes, phenyl blocking groups are used during synthesis of the fluoro dinitro moiety and are then replaced with bromine and the monomer is hydrolyzed.
