23 Jul Method for preparing tough integrated biomimetic layered graphene composite material
Abstract
The invention discloses a method for preparing a tough integrated biomimetic layered graphene composite material. Inorganic graphene oxide and organic dopamine are formed into a bionic building layered graphene composite material by an evaporation-induced self assembly method under the inspiration of a natural abalone shell organic-inorganic micro-nano multi-stage layered assembly structure and organic-inorganic crosslinking. The obtained imitated abalone shell layered composite material not only has high strength, but also has high toughness, the strength is twice of that of the natural abalone shell, the toughness is 1.5 times of that of the natural abalone shell, and meanwhile, the biomimetic layered graphene composite material also has excellent conductivity, and has potential application in the fields such as aviation and aerospace, tissue engineering, capacitor electrodes and the like.
