Embodiment 1

[0018] see figure 1 , is a flow chart of a method for preparing a dielectric substrate provided in Embodiment 1 of the present invention, and the method includes:

[0019] S11: Obtaining biocompatible whiskers by hydrothermal method.

[0020] Among them, the biocompatible whiskers can be AIO(OH) or Ca 10 (PO 4 ) 6 (OH) 2 .

[0021] For example, with Al(OH) 3 Colloids are used as precursors for Al(OH) 3 The colloid was hydrothermally treated to transform it into boehmite AIO(OH).

[0022] S12: depositing the biocompatible whiskers obtained in step S11.

[0023] For example, AIO(OH) is deposited so that AIO(OH) forms a sheet.

[0024] S13: Calcining the deposited biocompatible whiskers to obtain biocompatible paper.

[0025] For example, calcination of flake-shaped AIO(OH) obtained after deposition under normal pressure conditions yields α-Al 2 o 3 Whisker paper.

[0026] S14: forming a layer of resin on the surface of the biocompatible paper to obtain a medium subs...

[0030] see figure 2 , is a flowchart of a method for preparing a dielectric substrate provided in Embodiment 2 of the present invention, and the method includes:

[0031] S21: Obtaining biocompatible whiskers by a hydrothermal method.

[0032] Among them, the biocompatible whiskers can be AIO(OH) or Ca 10 (PO 4 ) 6 (OH) 2 .

[0033] For example, with Al(OH) 3 Colloids are used as precursors for Al(OH) 3 The colloid was hydrothermally treated to transform it into boehmite AIO(OH).

[0034] S22: Wash and filter the biocompatible whiskers with water to remove surface residues.

[0035] Wherein, the surface residues of the biocompatible whiskers are ions or molecules. For example, to remove ions or molecules from the surface of AIO(OH).

[0036] S23: depositing the filtered biocompatible whiskers.

[0037] For example, AIO(OH) is deposited so that AIO(OH) forms a sheet.

Abstract

Embodiments of the invention provide a dielectric substrate manufacturing method, which comprises obtaining biocompatible crystal whiskers by a hydrothermal method; subjecting the biocompatible crystal whiskers to deposition; calcining the deposited biocompatible crystal whiskers to obtain a biocompatible paper sheet; and forming a resin layer on the surface of the biocompatible paper sheet to obtain a dielectric substrate. The method has simple process and can avoid damage caused by the fibrous crystal whiskers absorbed into a human body to the human body.

Description

【Technical field】 [0001] The invention relates to the technical field of artificial composite materials, in particular to a method for preparing a dielectric substrate. 【Background technique】 [0002] Fiber-reinforced resin matrix composites are widely used as substrates for circuit boards and metamaterials. Traditional fiber-reinforced resin matrix composites are prepared from resins, fillers, and glass fibers. Commonly used resins are epoxy resins and unsaturated polyester resins. At present, the commonly used ones are: thermosetting resins, thermoplastic resins, and various modified or blended matrices. Thermoplastic resins can be dissolved in solvents, and can also soften and melt into viscous liquids when heated, and harden after cooling; thermosetting resins can only be heated and molded once, and solidify during processing to form infusible and insoluble Network cross-linked polymer compound, so it cannot be regenerated. The resin matrix of composite materials is c...
