Excessive usage from disposable medical face masks has significantly contributed to the global plastic waste issue since outbreak of COVID-19 pandemic. As a main ingredient in manufacturing process masks, non-renewable polypropylene (PP) polymer poses environmental challenges. Additionally, PP-based electrostatic filter, known for its high filtration efficiency, cannot maintain effectiveness long periods service. In this research, we demonstrate potential dextrin, biomass-derivative, as more sustainable alternative PP electret. Due dextrin being produced natural starch products, it is renewable material that biocompatible and eco-friendly. The hydrophilic rich content hydroxyl groups allows be processed environmentally friendly way with water. However, hydrophobic electret filter preferred prevent sharp decrease efficiency. By adding sodium methylsiliconate (SMS), hydrophobicity blended dextrin-SMS can inherent prolonged charges over 100 days. Ultimately, non-woven nanofiber using successfully an industrial compatible electrospinning technique combined addition polyethylene oxide (PEO) enhance electrospinability filter.

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.

Micro/nanofiber-based face masks are recommended as personal protective equipment (PPE) against particulate matter (PM), especially PM0.3. Ensuring thermal comfort in daily use is essential many situations. Here, radiative management introduced into to elevate the user comfort. An interlayered poly(lactic acid) (PLA) micro/nanofibrous filter effectively captures PM0.3 (99.69%) with minimal pressure drop (49 Pa). Thermal regulation accomplished by controlling mid-infrared (MIR) emissivity of mask's outer surface. Cooling feature cotton nonwovens high MIR (90.7%) for heat dissipation, while warming utilize perforated Al/PE films (10.7%) warmth retention. Skin temperature measurements indicate that skin covered cooling mask could be 1.1 °C lower than 3M mask, 1.3 higher mask.
