Abstract

A method of forming a porous material having improved compressive strength, includes forming an aerogel precursor that includes a polymer having a functional group capable of undergoing a crosslinking reaction dispersed in a dispersion medium. The precursor also includes a crosslinking agent. The aerogel precursor is frozen so that the dispersion is solidified, and freeze dried to sublime the dispersion medium and form the porous material. The crosslinking agent is reacted with the functional group to effect crosslinking, thus improving the compressive strength of the porous material.
