Abstract
Aerogels can be fabricated from pristine graphene exfoliated nanosheets using freeze gelation with nonaqueous solvents and no heat treatment or reduction stage. Solvents are selected that disperse pristine graphene with a melting point above room temperature but with a high vapor pressure above the solid at room temperature, enabling sublimation (freeze drying) under ambient conditions.
