Plasma textiles as fibrous filter media

Fabrication of stretchable and high‐filtration performance melt‐blown nonwoven webs for PM0.3 aerosol filtration

“…3 Filtering materials separate aerosols from polluted environments by different filtration mechanisms such as Brownian diffusion, interception, or inertial impaction. 4 Brownian diffusion is one of the mechanical filtration mechanisms where particles undergo unpredictable random vibration and stick to the fiber of filter webs. Relatively small particle sizes are captured in diffusion but for bigger size particles like PM 2.5 and PM 10 interception and/or inertial impaction are the favorite filtering techniques.…”

“…Therefore, researchers have started to work on combining electrostatic with mechanical aerosol-capturing mechanisms. 4 Zhang et al studied a novel methodology of aerosol filtration using melt-blown polypropylene fibers treated with corona charging. In their study, it was determined that for filtering PM 0.3 four-layer filters have shown a remarkable filtration efficiency of 99.03% against a lowpressure drop of 82.32 Pa and a high-quality factor of 0.056 Pa À1 .…”

“…To keep the health standard of humans at a higher level, the demand for filter materials is inevitable 3 . Filtering materials separate aerosols from polluted environments by different filtration mechanisms such as Brownian diffusion, interception, or inertial impaction 4 …”

“…Although many aerosols are captured via mechanical filtration mechanisms, tiny aerosols like PM 0.3 are not completely filtered out using filtering materials. Therefore, researchers have started to work on combining electrostatic with mechanical aerosol‐capturing mechanisms 4 …”
