Title: Multifunctional Superelastic Graphene Aerogels Derived from Ambient-Dried Graphene Oxide/Camphene Emulsions

Journal Article · · Materials Letters

Graphene oxide (GO) emulsions have been widely adopted to fabricate lightweight graphene aerogels (GAs). However, preparing high-performance GAs from conventional GO emulsions under ambient conditions seems rather challenging because of the structural collapse caused by strong capillary forces during drying. Here, we report a new, low-cost route to prepare high-performance, multifunctional GAs by the ambient drying of GO/camphene emulsions. Benefiting from the liquid-solid and solid-gas phase transitions of camphene, highly porous GO aerogels were obtained under ambient conditions. Moreover, the thermally annealed GO aerogels exhibited excellent mechanical properties, fire resistance, thermal insulation performance, and oil adsorption capability.
