Reinforced aerogel composition with hydrophobic properties and high thermal stability
The patent application (Publication Number: US20240026121A1) describes a reinforced aerogel composition that includes a reinforcement material such as fibers or foam, an inorganic aerogel with siloxy polymers, and alkyl hydrophobic groups covalently bonded to the silicon of the siloxy polymers. The composition is hydrophobic, with a liquid water uptake of 40 wt. % or less and alkyl hydrophobic groups with an onset of thermal decomposition of no less than 525° C. The alkyl hydrophobic groups may include a methyl group or methylsilyl groups, and the silicon bonded to these groups can be trifunctional or quadfunctional silicon.
Furthermore, the composition may have a hydrophobic organic content ranging from 1 wt. % to 15 wt. %, with variations specified in claims 7 and 8. The reinforced aerogel composition can have a liquid water uptake of 20% or less and may include additives like silicon carbide or opacifiers. The composition can also be in the form of a thin sheet, with thicknesses ranging from less than 1 mm to 3 mm. Additionally, the composition can exhibit resilience of 25% to 50% and flexibility of 5° to 65° according to ASTM C1101, as specified in claims 18 and 19. These claims outline the specific characteristics and components of the reinforced aerogel composition, highlighting its unique properties and potential applications in various industries.
