Problems solved by technology

[0004] However, since graphene is a two-dimensional solid material, the interaction between its own fluid interface properties and its surrounding environment affects the properties of graphene itself. It is easy to form the coupling of multiple physical mechanisms, which will cause the inter-molecular force and surface force to compete with each other, making the interface shape complex such as wrinkles, affecting the flatness and thermodynamic instability of the coating material, making it difficult to guarantee the reliability of the material

Description

technical field [0001] The invention belongs to the technical field of material processing and preparation, and in particular relates to an aluminum-based graphene-based composite material and a preparation method and application thereof. Background technique [0002] Basic equipment and people's property safety are closely related to personal safety. Traditional insulating materials are prone to aging and low strength, which leads to frequent safety accidents. Graphene composite materials have the characteristics of high strength, toughness, damage resistance and light weight, and excellent thermal conductivity. Adding one percent graphene to plastics can make plastics have good electrical conductivity; adding one percent Graphene can increase the heat resistance of plastics by 30 degrees Celsius. This can be applied in the fields of industrial and civil equipment and construction to achieve high strength, corrosion resistance, and lightweight products, which has important...
