▎ 摘　　要

NOVELTY - The defective graphene/wave-transmitting ceramic composite wave absorbing material, comprises defective graphene and wave-transmitting ceramics orderly deposited on the surface of wave-transmitting nanowires. The deposition thickness of the wave-transmitting ceramics is 10-50 nm. USE - Defective graphene/wave-transmitting ceramic composite wave absorbing material used as an electromagnetic wave protection material such as flexible wave-absorbing film and elastic wave-absorbing foam (claimed). ADVANTAGE - The method is simple and controllable, and the thickness of each layer of materials is in the nanometer scale, so the preparation period is short, and the cost is low. The method has the beneficial effect of being able to realize large-scale production. The material basically does not change the original flexibility and strength of the nanowire. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the defective graphene/wave-transparent ceramic composite wave-absorbing material, which involves putting the wave-transparent nanowires into a graphene deposition furnace, depositing defective graphene on the surfaces of the wave-transparent nanowires at 900-1200 ℃ and 5-10 kPa for 0-60 minutes by adopting a chemical vapor deposition method; putting the wave-transparent nanowire sample deposited with the defective graphene into a wave-transparent ceramic deposition furnace, adjusting process parameters, and controlling the deposition thickness of the wave-transparent ceramic to be 10-50 nm; and regulating and controlling the cycle times of the above steps to be 1-3 times, and preparing the nanowire wave-absorbing material with the multilayer alternative defect graphene/wave-transparent ceramic alternative structure. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the preparation process of defective graphene/wave-transmitting ceramic composite wave absorbing material.
