Preparation of Graphene/Polymer Composite Sponge for Pressure

The graphene/polymer composite sponge was prepared by self-assembly of water-soluble chloroprene on 3D graphene sponge and freeze drying. The composite sponge possesses 3D interconnected skeleton structure. This unique structure not only maintains the physical properties of graphene sponge, but also effectively transfers load from graphene sponge to polymer skeletons under compressive deformations. The composite sponge shows promising applications in pressure-sensing sensors
