Aerosol particles, such as the widespread COVID-19 recently, have posed a great threat to humans. Combat experience has proven that masks can protect against viruses; however, the epidemic in recent years has caused serious environmental pollution from plastic medical supplies, especially masks. Degradable filters are promising candidates to alleviate this problem. Degradable nanofiber filters, which are developed by the electrospinning technique, can achieve superior filtration performance. This review focuses on the basic introduction to air filtration, the general aspects of face masks, and nanofibers. Furthermore, the progress of the state of art degradable electrospun nanofiber filters have been summarized, such as silk fibroin (SF), polylactic acid (PLA), chitosan, cellulose, and zein. Finally, the challenges and future development are highlighted.
气溶胶颗粒,如最近广泛传播的 COVID-19,对人类构成了巨大威胁。战斗经验证明,口罩可以预防病毒;然而,近年来的疫情导致塑料医疗用品,特别是口罩,造成了严重的环境污染。可降解过滤器是缓解这一问题的有希望的候选物。可降解纳米纤维过滤器是通过静电纺丝技术开发的,可以实现卓越的过滤性能。本综述重点介绍空气过滤的基本原理、口罩的一般方面和纳米纤维。此外,还总结了丝素蛋白 (SF)、聚乳酸 (PLA)、壳聚糖、纤维素和玉米醇溶蛋白等艺术降解电纺纳米纤维过滤器的最新进展。最后,强调了挑战和未来发展。
