Abstract The filtration of airborne particulate matter (PM) and aerosols utilizing nonwoven fibrous materials has received significant research concern due to the continuing global pandemics, especially outbreak coronavirus disease (COVID-19), particularly for face masks as a measure personal protection. Although spun-bond or melt-blown fabrics are among pioneer in development polymer microfiber-based air filters on large scale, relatively new manufacturing processes like electrospinning solution blow spinning (SBS) gaining momentum manufacturers filter membranes. high performance nanofiber is their surface area volume ratio which increases interaction between PM improves electrostatic charge distribution electret filters, allowing enhanced capture capability based deposition. Moreover, small diameter nanofibrous breathability mask by providing slip effect, turn reduces pressure drop through membrane. This paper provides comprehensive review contemporary advances masks, detailing working mechanism involved, reviewing recent experimental studies, discussing improvements efficiency three main strategies, including mechanical antimicrobial functionality. Furthermore, prospective introduced considers synergistic combination effects mechanisms designing multifunctional structure that can efficiently wide range with higher lower drops pressure. New trends activity smart material-based membranes fight against infectious agents also described.

Despite the great potential in fabrication of biodegradable and eco-friendly air filters by electrospinning poly(lactic acid) (PLA) membranes, filtering performance is frequently dwarfed inadequate physical sieving or electrostatic adsorption mechanisms to capture airborne particulate matters (PMs). Here, using parallel spinning approach, unique micro/nanoscale architecture was established conjugation neighboring PLA nanofibers, creating bimodal fibers electrospun membranes for enhanced slip effect significantly reduce resistance. Moreover, bone-like nanocrystalline hydroxyapatite bioelectret (HABE) exploited enhance dielectric polarization properties PLA, accompanied controlled generation junctions induced microaggregation HABE (10-30 wt %). The incorporated supposed orderly align applied E-field largely promote charging capability surface potential, gradually increasing 7.2 kV from lowest level 2.5 pure PLA. This mainly attributed HABE-induced orientation backbone chains C═O dipoles, as well interfacial charges trapped at interphases HABE-PLA crystalline region-amorphous Given multiple capturing mechanisms, micro/nanostructured PLA/HABE were characterized excellent sustainable performance, e.g., filtration efficiency PM0.3 promoted 59.38% 94.38% after addition 30 % a moderate airflow capacity 32 L/min 30.78 83.75% highest 85 L/min. It interest that pressure drop decreased, arising between ultrafine nanofibers conjugated microfibers. proposed combination nanostructured electret multistructuring strategy offers function integration efficient low resistance are highly useful pursue fully filters.
