23 Jul Preparation method of bionic layered tough integral conductive graphene composite material
Abstract
The invention relates to a preparation method of a bionic layered tough integral conductive graphene composite material. In the nature, an abalone shell has excellent mechanical strength and toughness with its organic-inorganic micro-nano multi-level layer-by-layer assembly structure and composite interface. With the inspiration of the micro-nano multi-level structure and composite interface of the abalone shell, an inorganic phase graphene oxide and an organic phase chitosan are bionically constructed into a high-strength high-toughness conductive layered graphene composite material with a method of self-assembly induced by vacuum suction filtration. The tensile strength of the material is 4 times that of natural abalone shell, and the toughness of the material is 10 times that of natural abalone shell. The material also has excellent electrical conductivity, and can be widely applied in the fields of aerospace, capacitor electrode, tissue engineering, and the like.
