Abstract

The invention discloses an anti-microbial coating prepared from a photon up-conversion material. The anti-microbial coating contains a photocatalyst TiO2 and an up-conversion material NaYF4:Yb3+, Er3;a heterogeneous structure is formed between TiO2 and NaYF4:Yb3+, Er3; a transparent coating prepared through a sol-gel process is arranged on the titanium dioxide-doped up-conversion material NaYF4:Yb3+, Er3. The invention also provides a preparation method for the anti-microbial coating. The preparation method comprises the following steps: (1) compounding the up-conversion material NaYF4:Yb3+,Er3; (2) compounding the titanium dioxide-doped up-conversion material NaYF4:Yb3+, Er3; (3) compounding a sol-gel coating. The anti-microbial coating disclosed by the invention can take effect under the condition of ordinary illumination and can avoid harm of ultraviolet light to human and livestock.

Description

technical field [0001] The invention relates to the technical field of antibacterial coatings, in particular to an antibacterial coating prepared by using a photon up-conversion material and a preparation method thereof. Background technique [0002] In the public transportation and medical systems of big cities, public health and environmental cleanliness are always issues of concern to the public and cannot be underestimated. Not only pollutants will exist in the air, but bacteria and viruses can also spread through various surfaces as media (such as: door handles, handrails, faucets and elevator buttons, etc.). At present, one of the most commonly used solutions for surface disinfection and pollutant treatment is deposition of photocatalytic coating (PCC), which is to coat the surface of the object with a coating with photocatalytic oxidation properties to oxidize the pollution in the air objects and eliminate microorganisms on objects. [0003] At present, a relatively...
