Embodiment

[0029] Pipette 100ml of silane coupling agent (KH550) stock solution into a beaker, add 10ml of distilled water, and dropwise add oxalic acid solution to adjust the pH value to 3.5. Stir to dissolve and make up a 20% by weight solution. Take 0.5ml of KH550 aqueous solution, mix with 1g of silicon nitride and 29.5ml of acetone, stir vigorously for 2 minutes, control the speed at 1800r / min, and let the formed suspension stand still.

[0030] The silicon nitride powder pretreated by the coupling agent is mixed with the polyphenylene ether press, and the weight of the silicon nitride is controlled to be 10%. Stir with an ultrasonic oscillator. Diethylenetriamine was then added, stirring continued, and poured into molds. Put it into an oven and keep it warm for 50 minutes at 120° C., cool naturally to room temperature, and demould, so as to obtain the substrate material of the present invention.

Abstract

The invention relates to a base plate material. The base plate material includes Si3N4, polyphenyl ether and polyphenyl ether auxiliaries. The base plate material disclosed by the invention is low in electric constant and good in thermal conductivity.

Description

【Technical field】 [0001] The invention relates to a metamaterial, in particular to a metamaterial dielectric substrate material and a preparation method thereof. 【Background technique】 [0002] Metamaterials are generally composed of multiple metamaterial functional plates stacked or combined in other regular arrays. A metamaterial functional plate generally includes a dielectric substrate and a plurality of artificial microstructures arrayed on the dielectric substrate. The dielectric substrate of the metamaterial in the prior art is an organic or inorganic substrate of uniform material, such as FR4, TP1 and so on. Multiple artificial microstructures arrayed on a dielectric substrate have specific electromagnetic properties and can generate electromagnetic responses to electric or magnetic fields. By precisely designing and controlling the structure and arrangement of the artificial microstructures, metamaterials can exhibit various Electromagnetic properties that ordinar...
