20.500.12556/RUL-152678 Single-layer and double-layer filtration materials based on polyvinylidene fluoride-co-hexafluoropropylene nanofibers coated on melamine microfibers In this work, we demonstrate selected optimization changes in the simple design of filtration masks to increase particle removal efficiency (PRE) and filter quality factor by combining experiments and numerical modeling. In particular, we focus on single-layer filters fabricated from uniform thickness fibers and double-layer filters consisting of a layer of highly permeable thick fibers as a support and a thin layer of filtering electrospun nanofibers. For single-layer filters, we demonstrate performance improvement in terms of the quality factor by optimizing the geometry of the composition. We show significantly better PRE performance for filters composed of micrometer-sized fibers covered by a thin layer of electrospun nanofibers. This work is motivated and carried out in collaboration with a targeted industrial development of selected melamine-based filter nano- and micromaterials. nanofibers aerosols filtration simulations modeling fibers layers nanoparticles nanovlakna aerosoli filtracija true false true Angleški jezik Slovenski jezik Članek v reviji 2023-12-04 11:13:04 2023-12-04 11:13:05 2023-12-05 03:41:06 0000-00-00 00:00:00 2023 0 0 Str. 15807-15819 iss. 17 Vol. 6 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.3 2574-0970 10.1021/acsanm.3c02592 162583555 potisk-et-al-2023-single-layer-and-double-layer-filtration-materials-based-on-polyvinylidene-fluoride-co.pdf potisk-et-al-2023-single-layer-and-double-layer-filtration-materials-based-on-polyvinylidene-fluoride-co.pdf 1 D24886B2AAF0E80BACEDD91BCDF1BACB bc7e57e63553f9b87bd4ef6d98f7ba7bde0f38c701df3e9e0fd9f4f1c792317b 13028677-928e-11ee-9ca9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178283 https://pubs.acs.org/doi/10.1021/acsanm.3c02592 0 d6bf8624-928d-11ee-9ca9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178282 Fakulteta za matematiko in fiziko 0 0 0
