Deng.In addition, theoretically most solid-state materials surface can be processed in femtosecond laser, including semiconductor, metal, polymer, height are firmly
Crisp glass material, ceramics, even biomaterial etc..The side that this technology can be scanned on extensive material surface by a step
Method directly constructs micrometer/nanometer classification composite construction.Since the wetability of material surface not only forms decision by surface chemistry,
Extreme influence also by surface micro-nano pattern, thus the surface after these femtosecond laser ablations usually show it is various solely
Special wetting property.Super-drainage structure and femtosecond laser technology be not so far yet applied to the surface treatment of mask filter material and production system
In making.
Utility model content
Defect and deficiency based on the prior art, the technical problem to be solved by the utility model is to how to eliminate because exhaling
Mask inner surface caused by gas moistens out and then caused bacterium, virus, haze particle are deposited and bred.
The utility model provides a kind of mask filter material being surface-treated through femtosecond laser, and using the antifog of filter material preparation
Haze mask.The utility model uses femtosecond laser technology, handles surface of filter medium, forms super-hydrophobic interface.When mask internal fan opens
It is dynamic, it is easy to get rid of the bacterium being attached on filter material, virus and haze particle, increase the service life of mask, reach long-term
The purpose used.
The utility model is realized by following technical proposals:
