Claim 0:
1. A method for making a three-dimensional micro-architected aerogel, comprising:
(a) curing a reaction mixture comprising a co-sol-gel material and at least one catalyst to obtain a crosslinked co-sol-gel, wherein step (a) comprises curing the reaction mixture at a temperature of 100° C. or less;
(b) providing a photoresin comprising a solvent, a photoinitiator, a crosslinkable polymer precursor, and a dispersion of the crosslinked co-sol-gel;
(c) curing the photoresin using projection microstereolithography layer-by-layer to produce a wet gel having a pre-designed three-dimensional structure;
(d) drying the wet gel to produce a dry gel; and
(e) pyrolyzing the dry gel to produce a three-dimensional micro-architected aerogel.
