A kind of preparation method of three-dimensional graphene composite material

Abstract

The invention provides a method for preparing a three-dimensional graphene composite material. The three-dimensional graphene structure is pre-prepared by 3D printing, and then compounded with a filling material to prepare the three-dimensional graphene composite material. The method has simple steps, low cost, and high efficiency; the process of preparing the three-dimensional graphene structure does not require the use of chemical reagents, additional processing technology assistance, or processing under a special atmosphere, and rapid prototyping is realized; at the same time, the prepared The structure of the three-dimensional graphene composite material is controllable, which can realize the printing of multi-scale complex three-dimensional graphene structure, and the obtained composite material has excellent comprehensive properties.
