Abstract

The invention relates to a functional composite adopting a core-shell structure and a preparation method of the functional composite, in particular to a butylbenzene particle / graphene / aluminum composite with high electromagnetic shielding performance and a preparation method thereof. Composite particles of the composite take graphene-coated nanoscale butylbenzene particles as a core structure andan aluminum film layer as a core shell, wherein the content of the graphene-coated nanoscale butylbenzene particles is 90vol%-98vol%, the content of metal aluminum is 2vol%-10vol%, and the content ofgraphene in the composite particles is not lower than 0.05vol%. By preparation of the composite particles adopting the multilayer structure, the electrical conductivity and electromagnetic shielding performance of the composite can be significantly improved and the specific gravity of the material can be reduced under the condition of low-content aluminum metal and trace graphene, and the purposesof low specific gravity, high conductivity and high electromagnetic shielding performance are achieved.

Description

technical field [0001] The invention relates to the field of functional composite materials, in particular to a styrene-butadiene particle / graphene / aluminum composite material with high electromagnetic shielding performance and a preparation method thereof. Background technique [0002] With the development and popularization of electronic information technology, "electromagnetic pollution" has attracted more and more attention. For electromagnetic protection, in addition to requiring good electromagnetic shielding and wave-absorbing performance, it also requires light weight, thin thickness, and environmental tolerance. Good, excellent mechanical properties and so on. Conductive polymer composite materials have many advantages, such as light weight, easy processing, low cost, controllable electrical conductivity, and wide application range. They have become the most promising research and application direction in the field of electromagnetic shielding materials. However, c...
