Title: Fabrication of nanoporous aerogels via freeze substitution of nanowire suspensions

Abstract

A method of making a nanoporous aerogel includes the steps of providing nanowire suspensions, freeze casting the nanowire suspensions to produce freeze-cast gels, extracting the frozen medium from the freeze-cast gels by freeze-substitution with a solvent to produce wet gels, modifying or functionalizing the wet gels as needed, and drying the wet gels to produce a nanoporous aerogel.
