Abstract
Aerogel monoliths are treated with silanes or transition metal-containing reagents by chemical vapor deposition. This treatment improves the mechanical strength of the aerogel while maintaining their high surface area, low density, and porosity. When silane containing reagents are used, the transparency is generally maintained.
Claims21
A method for increasing the strength of an aerogel monolith comprising diffusing a gaseous reagent comprising a silane-containing or transition metal-containing reagent into a precursor aerogel monolith by chemical vapor deposition.
A transparent aerogel monolith prepared by a method comprising diffusing a gaseous reagent comprising a silane-containing or transition metal-containing reagent into a precursor aerogel monolith by chemical vapor deposition.
A transparent aerogel monolith comprising a Young's modulus of from about 3 MPa to about 9 MPa.
