Abstract
Description
technical field
[0001] The invention relates to the field of air purifiers, in particular to an air filter and its preparation method and application. Background technique
[0002] In order to prevent the spread of diseases, researchers generally use droplets and air as the medium, and use filter materials to prevent the spread of microorganisms. However, the bacteria and viruses enriched on the surface of the filter material can still maintain their activity. Simple filtration interception is not enough to suppress the microbial contamination of the filter material during reuse and disposal. It is necessary to develop a filter material that can quickly inactivate microorganisms.
[0003] Adding features to prevent spore germination and microbial survival in air filtration units will help reduce the risk of disease and allergic reactions. The antimicrobial functional layer also prolongs the service life of the filter unit. Microbial activity shortens the life cycle of the ...
