The demand for face masks is increasing exponentially due to the coronavirus pandemic and issues associated with airborne particulate matter (PM). However, both conventional electrostatic- nanosieve-based mask filters are single-use not degradable or recyclable, which creates serious waste problems. In addition, former loses function under humid conditions, while latter operates a significant air-pressure drop suffers from relatively fast pore blockage. Herein, biodegradable, moisture-resistant, highly breathable, high-performance fibrous filter developed. Briefly, two biodegradable microfiber nanofiber mats integrated into Janus membrane then coated by cationically charged chitosan nanowhiskers. This as efficient commercial N95 removes 98.3% of 2.5 µm PM. physically sieves fine PM provides low pressure differential 59 Pa, comfortable human breathing. contrast dramatic performance decline when exposed moisture, this exhibits negligible loss therefore multi-usable because permanent dipoles adsorb ultrafine (e.g., nitrogen sulfur oxides). Importantly, completely decomposes within 4 weeks in composting soil.

The health-threatening air pollution, especially from particulate matter (PM), has triggered increasing demands for developing low-cost and long-service-life air-cleaning technologies. In the present contribution, a range of high-efficiency textiles/metal-organic framework (MOF) composites (MOFs@textiles) filters with excellent washable reusability is presented. By processing MOFs onto textile substrates via an eco-friendly solvent-free method to enable microporous feature also strong PM adhesion, we develop flexible, highly effective >95.00% removal efficiency (e.g., MiL-53(Al)@Aramid, PM2.5: 95.30%, PM10: 96.11%) under harmful quality conditions (average PM2.5 mass concentration > 280 μg m-3 PM10 360 m-3). Therefore, these MOFs@textiles are promising producing efficient recyclable out-/indoor purifiers.

Abstract Metal‐organic frameworks (MOFs), an emerging class of porous organic‐inorganic hybrid materials, have shown great potential for water and wastewater treatment applications. However, pure MOF powders limited practical applications in due to their insolubility, poor processability, brittleness, safety hazard from dust formation, difficult separation aqueous solutions. Thus, exploring MOFs composites with improved performance is importance. The marriage electrospun nanofiber forethought into the final product's morphology, structure, chemistry has opened up new opportunities efficient treatment. present review exhaustively summarizes strategies integrate nanofibers via electrospinning remove various pollutants (i.e., organic dyes, heavy metal ions, pharmaceuticals, personal care products, oily compounds, solvents, etc.) adsorption, photodegradation, membrane filtration. Besides, most recent advances current challenges future outlook are delineated.

Air-purification utilizing an air filtration system is vital in maintaining optimum interior quality, despite the highly polluted that anthropogenic activities have exacerbated. Since constituents of pollutants are so unstable and diverse, conventional air-filtering materials made glass fibres or non-biodegradable polymers facing a considerable dilemma completely removing particulate finer size like PM2.5 gaseous harmful chemicals, CO2, other contaminants. These synthetic likewise non-biodegradable, resulting their disposal landfills. Therefore, developing fully biodegradable filtering for purification undeniably urgent. Cellulose widely dispersed natural biopolymer due to its porous, sustainable surface-modifiable nature, it has demonstrated extraordinary relevance numerous fields, including as high-performance system.
