A resilient and lightweight cellulose/graphene oxide/polymer-derived multifunctional carbon aerogel generated from Pickering emulsion toward a wearable pressure sensor.

In the new era of competitive smart electronics, the development of compressible multifunctional carbon aerogels is highly needed, but still faces enormous challenges. Here we demonstrate a robust strategy to fabricate multifunctional carbon aerogel via freeze-drying of cellulose nanofibers (CNF) and graphene oxide (GO) co-stabilized Pickering emulsion gel followed by high-temperature annealing. The resulting carbon aerogel exhibits tunable mechanical, hydrophilic and hydrophobic properties due to varying the elemental composition and the pyrolysis of introduced polymers.
