Sumary of Nanofiber face masks improve filtration efficiency, need replacing more often:
- Since its outbreak, the COVID-19 virus has infected more than 207.7 million people worldwide and has claimed more than 4.3 million lives, according to the World Health Organization coronavirus dashboard as of Aug.
- 17. However, many medical professionals attribute the consequential role of face masks in slowing the spread of the virus and protecting human health.
- However, the effects of microwater droplets on the integrity of nanofibers are relatively unclear.
- In Physics of Fluids, by AIP Publishing, researchers from Southern University of Science and Technology in Shenzhen, China, examine these ambiguities through a visualization of nanofibers interacting with water aerosol exposure.
- We have to look into it and see what exactly happened with the nanofibers.
- ” Yu and his colleagues used high-speed microscopic videos to systematically visualize the evolution of nanofibers made of polymers with different contact angles, diameters, and mesh sizes under water aerosol exposure.
- “Filming nanofibers is like taking portraits of babies,” said Yu.
- This is because nanofibers are very soft and flimsy, especially with the aerosol flow blowing through.
