Description

technical field

[0001] The invention relates to the field of synthesis of foamed aluminum nano-carbon composite materials, in particular to methods for preparing foamed aluminum / carbon nanotubes, foamed aluminum / fullerenes, foamed aluminum / graphene composite materials, and foamed aluminum / graphene oxide. Background technique

[0002] Aluminum foam is a new type of porous composite material composed of aluminum matrix and pores. It belongs to a branch of porous materials. It has dual properties of function and structure and is widely used. Nano-phase reinforced aluminum matrix composites are a new type of material that has been developed rapidly in recent years. It has the advantages of low density, corrosion resistance and good processing performance. As a one-dimensional nano-reinforced and toughened material, carbon nanotubes can greatly improve the strength, hardness, thermal stability, corrosion resistance, electrical conductivity, thermal conductivity and frictional pro...
