Problems solved by technology

Due to the large surface area of ​​graphene oxide, it is easy to agglomerate under the action of surface energy. The traditional electrodeposition process can only prepare a small amount of graphene oxide on the coating, and even cannot be prepared on the coating.
Due to the low content of graphene oxide on the surface of the coating obtained by the traditional electrodeposition process, it is difficult to improve the antibacterial performance of the coating

Abstract

The field of microbial protection of the present invention relates to an electrodeposition processing technology, specifically a method for preparing a metal-based graphene oxide antibacterial coating based on magnetic field-assisted scanning spray electrodeposition. The metal ion plating solution of graphene oxide is used as the raw material, and it is formed at one time by using the magnetic field-assisted spray electrodeposition technology; the antibacterial rate of the coating against E. The above; the antibacterial coating provided by the present invention does not need to be modified by adding an antibacterial agent, and has the reliability of the metal coating. The antibacterial coating prepared by this method has potential application space in the fields of public health and engineering protection.

Description

technical field [0001] The invention belongs to the field of microbial protection and relates to an electrodeposition processing technology, in particular to a method for preparing a metal-based graphene oxide antibacterial coating based on magnetic field-assisted scanning spray electrodeposition. Background technique [0002] In the natural environment, the existence of a large number of pathogenic bacteria has brought huge safety hazards to human survival, especially the development pattern of super-urbanization has further increased the urban population density, and put forward higher requirements for the field of public health. Therefore, an ideal long-term and reliable antibacterial coating can be used as an antibacterial surface for public facilities to ensure the safety of human public health. [0003] Electroplating layer is a common material for metal surface coating, mainly prepared by electrochemical deposition method. As a traditional antibacterial material, met...
