Novel ceramic wave-absorbing microsphere material and preparation method thereof
The invention provides a novel ceramic wave-absorbing microsphere material and a preparation method thereof. The preparation method comprises the following steps: mixing magnetic powder and PSA liquid, and emulsifying the mixture in a continuous phase; curing the emulsion; separating the precursor microspheres from the continuous phase; and carrying out ceramic treatment on the magnetic polymer. The preparation method of the novel ceramic wave-absorbing microsphere material disclosed by the embodiment of the invention is simple in process and easy to prepare under simple conditions, and meanwhile, large-scale industrial production can be realized. The wave-absorbing material prepared by the preparation method of the novel ceramic wave-absorbing microsphere material disclosed by the embodiment has good spherical morphology; since the polysilylacetylene has an active reaction site and an adjustable component structure and can react and crosslink with a magnetic substance, different microstructures are formed by adjusting the components and content of the magnetic substance; and therefore the absorption and reflection capabilities of the prepared wave-absorbing material on electromagnetic waves are changed.
