▎ 摘　　要

NOVELTY - Electromagnetic shielding material has a graphene oxide film that is utilized as substrate to construct vertical layered micro-structure by using laser scribing technology. USE - Electromagnetic shielding material for use in lightweight electromagnetic protection field i.e. defense military industry, aerospace, communication device and wearable electronic equipment. ADVANTAGE - The electromagnetic shielding material: exhibits rich graphene interface and defect, so that the electromagnetic wave entering the material can be reflected and absorbed for many times, which greatly improves electromagnetic shielding performance of the material; has excellent mechanical property based on vertical layered micro-structure; has good mechanical stability and durability when facing mechanical application scene i.e. cyclic stretching, bending or torsion; can realize mechanical buffer, so as to avoid fatigue damage or breakage of the material caused by stress of the material; has better controllability, which is more suitable for industrial mass production; and has lower density. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparation method of electromagnetic shielding material; and (2) control method of shielding mechanism of electromagnetic shielding material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of preparation method of electromagnetic shielding material (Drawing includes non-English language text).
