Compressible, conductive, ultralight, and superhydrophobicgrapheneaerogels (GAs) are promising for wearable electronics and adsorptionapplications. However, the unsatisfactory sensing performances andlack of multiscale structural regulation still impede the developmentof multifunctional GAs. Herein, a multifunctional aerogel based ongraphene/silk is reported a highly ordered three-dimensional(3D) reduced graphene oxide (rGO) conductive network is establishedby an alkali-induced hydrothermal self-assembly strategy, while silkfibroin (SF) bound to graphene oxide (GO) by electrostatic interactionsis uniformly distributed throughout the network. The ultralight rGO/SFaerogel (GSA) has the property that its resistance varies with compression,so it can be used for flexible pressure sensors. A GSA-based sensorcan detect compressive stresses down to 0.35 kPa and has a responsetime of 0.55 s and a recovery time of 0.58 s. It has a good linearresponse from 0.5 to 30 kPa with sensitivities of 0.54 kPa(-1) (0.5-4 kPa) and 0.21 kPa(-1) (4-30kPa), respectively. The GSA-based sensor also has excellent durability,remaining stable after 12,000 cycles. As proof of concept, its applicationsfor health monitoring, speech recognition, and motion capture areshown. Furthermore, the carbonized rGO/SF aerogels (C-GSAs) with superhydrophobicitycan adsorb various organic substances (146.7-278.8 g/g) andachieve oil-water separation.
