Abstract

The invention discloses a modified graphene-brass composite material. The modified graphene-brass composite material is characterized by being prepared from the following materials: 5-15% of grapheneand 1-5% of humic acid, with the balance being brass. The modified graphene-brass composite material of the invention adopts graphene and humic acid as complementary additives and utilizes the uniquemorphological and structural characteristic of humic acid, and through mutual fitting between humic acid and graphene, the dispersibility of graphene is promoted without destroying the surface morphological structure of graphene; at the same time, humic acid has structural and morphological traits similar to the structural and morphological traits of graphene, so humic acid can be auxiliarily usedas a reinforcing phase for reinforcing the performance of the composite material.

Description

technical field [0001] The invention relates to an organic material modified composite material, in particular to a graphene brass composite material, which belongs to the technical field of new composite materials. Background technique [0002] Graphene is a planar carbon material exfoliated from graphite. Graphene has a hexagonal lattice, and each carbon atom on the plane is connected by sp2 hybrid orbitals. The thickness of the graphene film is only 0.335 nanometers, and the carbon atoms in the plane form a space electron cloud with a large π bond before each other. This structure of graphene makes it have a unique performance that breaks through ordinary graphene materials. [0003] The unique advantages of graphene are mainly manifested in the joint structure of graphene plane sp2 hybrid orbitals. In the direction of graphene plane extension, graphene has super stability. At the same time, the large π bond makes graphene have super heat conduction, electronic conductiv...
