▎ 摘  要

NOVELTY - Preparing three-dimensional graphene functional composite laminated material involves dipping laser-induced two-dimensional graphene material into resin material liquid to obtain dipped two-dimensional graphene material, and hot press molding multiple layers of dipped two-dimensional graphene material. The resin material liquid comprises thermosetting resin and curing agent. USE - The method is useful for preparing three-dimensional graphene functional composite laminated material, which is useful in strain sensing, liquid sensing, radiating, electromagnetic wave shielding or electromagnetic wave absorption (all claimed). ADVANTAGE - The method has simple operation, and low cost, which greatly improves efficiency of forming three-dimensional graphene structure, and is convenient for preparation of large-sized product. The method can conveniently stack and shape macroscopic three-dimensional graphene functional composite laminated material with variable size and shape. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for three-dimensional graphene functional composite laminated material, prepared by above method.
