Abstract
Disclosed here is a method for making an architected three-dimensional aerogel, comprising providing a photoresin comprising a solvent, a photoinitiator, a crosslinkable polymer precursor, and a precursor for graphene, metal oxide or metal chalcogenide; curing the photoresin using projection microstereolithography layer-by-layer to produce a wet gel having a pre-designed three dimensional structure; drying the wet gel to produce a dry gel; and pyrolyzing the dry gel to produce an architected three-dimensional aerogel. Also disclosure is a photoresin for projection microstereolithography, comprising a solvent, a photoinitiator, a crosslinkable polymer precursor, and graphene oxide.
