Abstract
Disclosed herewith is a process of forming an aerogel composite which comprises introducing a gaseous material into a formed aerogel monolith or powder, and causing decomposition of said gaseous material in said aerogel in amounts sufficient to cause deposition of the decomposition products of the gas on the surfaces of the pores of the said aerogel. Also disclosed are the composites made by the process.
Claims16
A process of forming an aerogel composite, which process comprises:
- introducing a reactive gaseous material at 100.degree. C. or higher into the pores of a formed aerogel monolith or powder having a pore structure, and
- causing decomposition at 100.degree. C. or higher of said gaseous material on and within the pores of said aerogel in amounts sufficient to cause deposition of solid decomposition products of said gaseous material on the surface of the pores of said aerogel and for a sufficient time between a few minutes and 48 hrs to create an aerogel suitable for thermal insulation, photolytic catalysis, electrical battery electrode, luminescent functions, paramagnetic functions, superparamagnetic functions or ferromagnetic functions, wherein
- additional gas or vapor is introduced into the composite material, depositing within or reacting with the composite, forming yet another composite.
