Gradient, stretchable and superelastic reduced graphene oxide/polyurethane nanocomposite aerogels have been achieved by a sol-gel/hot pressing/freeze casting/ambient pressure drying strategy. The gradient aerogels can be used for high-efficient separators and wearable electronics with an ultrabroad detection range of 1 Pa–12.6 MPa and ultrahigh fatigue resistance, showing great potentials in high-performance sensors and separators.
