The durability and reusability of nanofiber filters are important characteristics, and the following are some specific information:

Durability: Nanofiber filters usually have good durability. For example, the tensile strength of the polyacrylonitrile /BaTiO3 composite nanofiber filter membrane is 75.5% higher than that of pure polyacrylonitrile (PAN) nanofibers

In addition, some nanofiber filter materials, such as polyimide (PI) nanofiber filter membranes, can maintain good thermal stability at temperatures up to 420 ° C, showing excellent mechanical properties.

Reusability: The reusability of nanofiber filters is also a significant advantage. For example, some nanofiber filters can be reused after washing, alcohol spraying or soaking, and their performance remains stable. Specifically, it has been reported that some nanofiber filters can be recycled up to 20 times. In addition, studies have shown that even after 5 cycles of reuse, the adsorption capacity of some nanofiber filters can still be maintained at 82.3%. It has also been reported that a nanofiber hydrogel film can be used 30 times, and after multiple uses, it is only necessary to re-inject the nanocellulose (NFC) water suspension to create a new hydrogel film for continued use.

Anti-pollution: The anti-pollution ability of the nanofiber filter membrane is also part of its durability. Some nanofiber filters inactivate biological particles by depositing components on the fibers, thereby improving the durability of the filters.
