Abstract

The invention provides a method for preparation a metamaterial. The method for preparation the metamaterial comprises the following steps of: forming a layer of cured resin film on a structral ceramic substrate; graving a groove with a predetermined mirostructure pattern on the cured resin film; injecting functional ceramic slurry into the groove; removing the cured resin film by sintering; sintering the functional ceramic slurry to form the predetermined microstructure pattern; and obtaining the metamaterial. The other embodiment of the invention further provides the metamaterial. The metamaterial comprises the structural ceramic substrate, and the functional ceramic adhered with the upper surface of the structural ceramic substrate, wherein the functional ceramic has the predetermined microstructure pattern. Therefore, the metamaterial with high mechanical strength, heat stability and electromagnetic properties is achieved.

Description

【Technical field】 [0001] The invention relates to composite material technology, in particular to a method for preparing a supermaterial and the supermaterial. 【Background technique】 [0002] Composite material is a mixture that has played an important role in many fields, replacing many traditional materials. Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature. [0003] In the prior art, the preparation of metamaterials is mainly achieved by forming a layer of metal on an insulating substrate, and then forming a microstructure on the metal layer. Structural ceramic materials have high mechanical strength and thermal stabi...
