Problems solved by technology

[0004] After carbon nanomaterials and metal materials are combined, the strength, hardness, wear resistance and thermal stability of the metal can be improved, but the traditional method combines carbon nanomaterials with metal Compounding requires the use of a binder in the middle, the presence of the binder will increase the resistance of the composite material, and the use of the binder also prevents the composite material from being used at a higher temperature to prevent the denaturation of the binder, carbonization

Abstract

The invention discloses a composite carbon nanomaterial and a preparation method thereof. The composite carbon nanomaterial comprises a carbon nanomaterial layer, a metal buffer layer and a matrix layer which are sequentially laminated, wherein the metal buffer layer is connected with the carbon nanomaterial layer through a solid solution structure, and the metal buffer layer is connected with the matrix layer through an alloy structure. According to the invention, the characteristic that some metal materials can form a solid solution with the carbon nanomaterial is utilized, so the metal materials serve as the buffer layer, and a carbon nanotube film and some metal materials which cannot form a solid solution with the carbon nanomaterial are combined together under the condition that a binder is not used; and the problem that the carbon nanomaterial is difficult to combine with metal materials under the condition that a binder is not used is solved.

Description

technical field [0001] The invention relates to the technical field of carbon nanomaterials, in particular to a composite carbon nanomaterial and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, higher requirements are placed on the performance of materials. The traditional single material can no longer meet the needs of the market. A composite material is a multiphase solid material composed of two or more substances with different physical or chemical properties. The composite material not only retains the characteristics of the original component materials, but also has a It has comprehensive performance superior to that of a single material. [0003] Since the discovery of carbon nanomaterials such as carbon nanotubes, graphene, and fullerene, their unique structure and excellent performance have attracted great attention from scientists. Combination of other materials has rapidly become a research hotsp...
