Summary: Layering micro and nano fibers using melt and solution electrospinning offers a novel approach for achieving high filtration efficiency with low pressure drop. The optimized process parameters can lead to fibrous mats with favorable filtration characteristics. The presence of higher ratios of nano-sub micrometer to super micrometer fibers in the fibrous matrix is associated with higher filtration quality factors.

Summary: The pore size distribution and pore number significantly influenced the air filtration performance of polysaccharide-based aerogels. Konjac glucomannan (KGM)/curdlan (KC) aerogels were prepared by vacuum freeze-drying, and their microstructure, molecular interaction, mechanical property, thermal stability, and air filtration performance were investigated. Results showed that KGM and curdlan had good compatibility and formed a complete aerogel structure. The addition of curdlan decreased the pore size and increased the pore number, resulting in improved filtration efficiency. KC0.9 was considered the optimal material for air filtration based on both filtration efficiency and air resistance.

Summary: Air transport carries various pollutants, such as particulate matter (PM), which can lead to cardiovascular and respiratory diseases. Controlling pollutant emissions before release poses a challenge. Filtration has been the most effective method for removing PM, and electrospinning has been applied to produce membranes with high filtration efficiency and low pressure drop. This review focuses on the synthesis of polymers for fabricating high-performance electrospun membranes to remove air pollutants, highlighting the influential parameters. The results demonstrate that electrospun membranes are an excellent alternative to air filters due to the versatility of the process, ability to control fiber diameter and porosity, and high efficiency with low pressure drop.

Summary: In order to tackle environmental pollution and emerging infectious diseases, it is crucial to develop highly efficient filters that can simultaneously remove air pollutants and pathogenic microorganisms. Traditional fibrous filter materials are not effective in capturing fine particles due to their wide fibers and large pores. This study utilized electrospinning to combine nano-spiderwebs with an ordered nanofiber membrane, creating an air-filtration material with a multi-stage pore structure that efficiently filters to deliver breathable air. The prepared composite nanofiber membrane demonstrated a filtration efficiency of over 98% for particulate matter smaller than 0.3 μm with a pressure drop of less than 100 Pa. The combination of nano-spiderweb/ordered structure effectively enhanced the filtration efficiency for fine particles. Additionally, the composite nanofiber membrane exhibited excellent bacterial filtration efficiency (>95%), showcasing its significant potential for air-filtration applications.

Summary: Poly (ε-caprolactone) (PCL)/zein/Ag nanoparticle (AgNP) fibrous membranes were prepared by ultrasonication-assisted electrospinning in this study. The membrane with 1% AgNP content and 30 minutes of sonication time exhibited the best performance in terms of air filtration and antibacterial/antiviral activity. The results showed that the bead-on-string morphology of the membrane contributed to its high performance due to the low packing density and the presence of open interconnected beaded airflow channels and small beads.

Summary: This study created a PVDF/SiO2/Ag composite nanofiber membrane with superhydrophobic and antibacterial properties using an electrospinning method. The membrane was deposited on PET fibers to create an air filter material. The results showed that the addition of nano-silver significantly improved the antibacterial performance while increasing the concentration of hydrophobic nano-SiO2 improved the hydrophobicity. The composite nanofiber membrane had a filtration efficiency of 99.94% for 0.3μm particulate matter and a drag pressure drop of 112.3 Pa, with a filtration efficiency for air microorganisms greater than 99.99%.
