Naturally dried superelastic bioinspired graphene aerogel for pressure/stretch sensing and separation

Flexible resistive tactile pressure sensors

“…Huang et al developed a superelastic graphene aerogel using freeze-casting technology and natural drying techniques. 172 This graphene aerogel exhibits excellent mechanical properties, high conductivity, and oil–water separation capabilities, making it a promising candidate for applications in flexible sensors and the cleanup of organic pollution or oil spills. Altynay Kaidarova et al utilized the piezoresistive effect of three-dimensional porous graphene, using laser printing of graphene on polyimide film to develop a flexible pressure sensor.…”

Bioinspired aerogels: ingenious structure, remarkable performance, and versatile applications

“…For instance, Huang et al imitated the structure of wood and used graphene oxide (GO) and ascorbic acid as raw materials to produce reduced graphene oxide (rGO) aerogels through combining freeze-drying and natural drying techniques. 125 Aerward, rGO/ silicone composites were created by inltrating silicone into rGO aerogel membranes to improve their stretch capacity (Fig. 9f).…”

Bionic structures for optimizing the design of stealth materials

“…In consequence, when it works, the low thermal conductivity and high temperature resistance can reduce the impact of temperature on the material as much as possible. Nevertheless, Deng et al 20 focused on graphene-based aerogels. They simulated the unique anisotropic structure of wood and obtained super-elastic rGO aerogels through simple preparation methods.…”
