| titleOfInvention | Light hollow carbon cube wave-absorbing material and preparation method thereof |
| abstract | The invention belongs to the field of material preparation, and particularly relates to a light hollow carbon cubic wave-absorbing materialA material and a preparation method thereof. The invention provides a preparation method of a light hollow carbon cubic wave-absorbing material, aiming at solving the problems of unmatched impedance, non-adjustable electromagnetic wave absorption frequency band and the like of a pure carbon wave-absorbing material prepared by the existing method and on the basis of fully utilizing a hard template to construct a hollow structure. The invention selects Cu 2 The O microspheres are used as hard templates, the light hollow carbon cubes are obtained through the processes of in-situ growth, calcination, template removal and the like, and Cu is adjusted 2 The thickness of the shell layer of the hollow carbon cube is regulated and controlled by the coating thickness of the poly-dopamine precursor on the O surface, so that the effective regulation and control of the conductivity characteristic of the carbon material can be realized in a small range, the wave-absorbing material with proper conductivity can be obtained according to the requirement, and the impedance matching and wave-absorbing effect of the material can be improved. The development of the light hollow carbon cubic wave-absorbing material is hopeful to be applied to the field of building wave-absorbing materials. |
