▎ 摘　　要

NOVELTY - The material has an accordion-shaped graphene hybrid material whose surface and interlayer are attached with magnetic nano particles, where wave-absorbing performance of the accordion-shaped magnetic graphene hybrid material is detected at an electromagnetic wave frequency band of 2 GHz to 18 GHz. Maximum reflectivity is calculated about 34dB. USE - Accordion-shaped graphene hybrid material. ADVANTAGE - The accordion-shaped graphene hybrid material has wave absorbing performance at the electromagnetic wave frequency band of 2 GHz to 18 GHz, the maximum absorption is -34dB, and is easy to control, and has high repetition rate, and stable conductivity and chemical stability of the graphene. The magnetic nano-particles are uniformly distributed between the graphene layers, and can be used as additive of the wave-absorbing material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an accordion-shaped graphene hybrid material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of an accordion-shaped graphene hybrid material.
