Embodiment

[0029] Provide 5g of diamond powder, a rolling device and a 5cm×5cm pine wood substrate.

[0030] Put 5g of diamond powder into 500mL of hydrogen peroxide and heat treatment at 90°C for 10h. Then the diamond powder was transferred to a muffle furnace and annealed in air at a temperature of 600° C. for 10 h to obtain the final oxygen-modified diamond powder.

[0031] Lay the oxygen-modified diamond powder on the wooden board, set the pressure of 5.8MPa on the rolling device to repeatedly roll the diamond powder on the wooden board until the diamond powder is completely embedded in the surface of the wooden board. Therefore, the diamond antibacterial coating is obtained on the surface of the wood board, and the coating quality is stable and the antibacterial performance is good, which solves the problem that the diamond powder is difficult to apply.

Abstract

The invention relates to the technical field of antibacterial coatings, discloses a diamond antibacterial coating technology, and aims to solve the problems of difficult application of diamond powderand the like in the prior art. The diamond antibacterial coating technology adopts a physical rolling pressing method and comprises the following steps that S1, diamond powder, a rolling pressing device and a target substrate are provided; S2, the diamond powder is subjected to oxygen modification, so that the surface of diamond is grafted with an oxidation functional group; and S3, the oxygen-modified diamond powder is flatly laid on the surface of the target substrate, rolling pressing is conducted on the flatly laid surface through the rolling pressing device, and the diamond powder is evenly embedded into the surface of the target substrate. A diamond antibacterial coating prepared through the physical rolling pressing method adopted by the diamond antibacterial coating technology is simple in operation process, stable in coating quality, good in antibacterial performance and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of antibacterial coatings, in particular to a diamond antibacterial coating technology. Background technique [0002] As one of the representatives of carbon nanomaterials, diamond powder has a competitive potential in the biomedical field due to its excellent biocompatibility. Especially in the field of antibacterial, diamond powder has been proven to have a highly effective bactericidal effect on Gram-negative and Gram-positive bacteria. [0003] Regarding the antibacterial mechanism of diamond, the oxygen-containing functional groups on the surface of diamond play a huge role in the antibacterial process of diamond. In the interaction with bacteria, the surface with oxygen-containing functional groups will generate active oxygen radicals, which will oxidize the cell wall of bacteria, causing the disorder of the internal environment of bacteria, thereby achieving the antibacterial effect.
