Description

technical field

[0001] The invention relates to a nano-type coating, in particular to a preparation method of the nano-type coating. Background technique

[0002] Due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles, they exhibit characteristics that conventional materials do not have in terms of magnetism, light, electricity, and sensitivity. Therefore, nanoparticles have broad application prospects in magnetic materials, electronic materials, optical materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. Generally speaking, nano-coatings must meet two conditions: first, at least one phase in the coating has a particle size in the range of 1-100nm; secondly, the presence of nano-phases can significantly improve the performance of the coating or have new features. function. However, the antibacterial effect of existing nano coatings is not good, the bactericidal rate...
