Can ultraviolet light be used to disinfect masks and prolong their service life?

At present, we have learned that ultraviolet radiation can decompose chemical bonds, leading to the reaction of plastics or other insulating materials, which leads to rapid aging. The medical masks we use contain polypropylene, which can also be aged by ultraviolet radiation. Once the masks are exposed for a long time, the protective effect will be discounted or disappear, which not only cannot prolong the service life, but also has a negative effect. Therefore, if a short time of irradiation has a certain disinfection effect, do not irradiate for a long time, which may lead to the failure of the mask!
