Abstract:

Air pollution is a serious threat to human health, and the respiratory-protection masks can effectively prevent the damage of air pollutants to health and the spread of respiratory infectious diseases. However, the traditional micron fiber masks have disadvantages such as non-reusable and single function. The nanofiber membrane respirator protective masks prepared by electrospinning technology shows many advantages such as high efficiency, low resistance and multi-function. In this review, the research progress of respiratory protective masks based on electrospun nanofiber membranes in recent years was reviewed from the perspectives of research background, working principle, preparation method and practical application. The research directions of electrospun nanofiber masks included durable nanofiber membrane masks, antibacterial nanofiber membrane masks, volatile organic compounds adsorption nanofiber membrane masks and degradable nanofiber membrane masks. Finally, the challenges and future research directions of electrospun nanofiber membrane respirator protective masks were discussed, and the new development directions of respirator protective masks in the future were pointed out, including good moisture resistance, excellent comfort and multi-pollutant integrated removal performance. The results showed that electrospun nanofiber mask had tremendous development potential and application foreground in respiratory protection and can better cope with the increasingly complex and diverse respiratory protection applications.
