AI Technical Summary

Problems solved by technology

[0004] At present, DLC is used as a friction-resistant coating, and it is mostly deposited on various alloys or glass substrates. However, due to the high stress, its application range is reduced, and the adhesion between the film layer and the substrate needs to be solved urgently.

Abstract

The invention discloses medical DLC film glass. The medical DLC film glass comprises a glass substrate, a first buffer layer, a second buffer layer, a DLC film layer and a modification layer, wherein the first buffer layer, the second buffer layer, the DLC film layer and the modification layer are sequentially arranged on the surface of the glass substrate, and the modification layer is an F-doped DLC film layer or an Ag-doped DLC film layer. The invention also relates to a preparation method of medical DLC film glass. The preparation method comprises the following steps: (1) pretreating the glass substrate; (2) preparing the first buffer layer; (3) preparing the second buffer layer; (4) preparing the DLC film layer; and (5) preparing the modification layer. The preparation method of the invention has the following beneficial effects: 1, the quality of an application vessel of sodium-calcium glass is greatly improved, and the water-blocking, oxygen-blocking and impurity diffusion-blocking capabilities of the sodium-calcium glass are improved; 2, the adhesion and the application reliability of the DLC film layer are greatly improved; 3, the hydrophobicity of glassware is greatly improved by the F-doped DLC layer; and 4, the Ag-doped DLC layer can greatly improve the sterilization and bacteriostasis capability of the glassware.

Description

technical field [0001] The invention belongs to the field of film technology, and in particular relates to a medical DLC film glass and a preparation method thereof. Background technique [0002] Diamond Like Carbon (DLC) has a graphite structure sp 2 bond and diamond structure sp 3 It has some excellent characteristics similar to diamond films, such as high hardness and high thermal conductivity, wide optical transmission range (refractive index is generally 1.5-2.6), good electrical properties (resistivity can reach 1000Ω·cm) and Biocompatibility; at the same time, it has properties different from diamond films, such as low film forming temperature (down to room temperature), high surface finish, and good friction and wear properties (friction coefficient as low as 0.2 or less), so it can be used in biomedical field. [0003] Chemical agents, especially those used for the human body, need to prevent the diffusion of impurities, prevent water and oxygen, and have good bi...
