SiBOC ceramic-based wave-absorbing metamaterial and preparation method thereof
The invention discloses a SiBOC ceramic-based wave-absorbing metamaterial and a preparation method thereof.The SiBOC ceramic-based wave-absorbing metamaterial is composed of a plurality of unit structures arranged in parallel, each unit structure is a hollow sphere-like polyhedron, and holes are vertically formed in the upper portion and the lower portion of each unit structure; the preparation method comprises the following steps: drawing a model of the SiBOC ceramic-based wave-absorbing metamaterial, carrying out 3D printing to obtain a SiBOC ceramic-based wave-absorbing metamaterial blank, carrying out curing, and carrying out high-temperature cracking to obtain the SiBOC ceramic-based wave-absorbing metamaterial. According to the preparation method, the photosensitive ceramic precursor is taken as a raw material, high-precision preparation of the SiBOC ceramic-based wave-absorbing metamaterial with a full-compact complex structure is realized through a DLP 3D printing process, the preparation method has the advantages of rapidness, high efficiency and low cost, the prepared wave-absorbing metamaterial shows obvious broadband wave-absorbing performance in a microwave band, the wave-absorbing performance has polarization insensitivity, and the wave-absorbing metamaterial has a wide application prospect. And stable wave absorption can be realized in a large-range incident angle, and the wave absorption performance stability is relatively high.
