PAN nano-cobweb-bead-on-string fiber composite membrane for air filtration / Yazhi Liu in CHEMICAL FIBERS INTERNATIONAL, Vol. 72, N° 4 (11/2022)  

[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 72, N° 4 (11/2022) . - p. 207-210 Titre : PAN nano-cobweb-bead-on-string fiber composite membrane for air filtration Type de document : texte imprimé Auteurs : Yazhi Liu, Auteur ; Yuepeng Xu, Auteur ; Zhaolin Liu, Auteur ; Wei Wang, Auteur ; Ni Wang, Auteur Année de publication : 2022 Article en page(s) : p. 207-210 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Caractérisation Composites à fibres Construction sandwich Electrofilature Filtres à air Membranes (technologie) Polyacrylonitrile Textiles et tissus à usages techniques Index. décimale : 677.4 Textiles artificiels Résumé : Sandwich structured polyacrylonitrile (PAN) nano-cobweb/bead-on-string fiber composite membranes were prepared by sequential electrospinning. With integrated features of ultra-fine nano-cobwebs and interconnected tortuous cavities among bead-on-string fibers, the composite membranes can exhibit very interesting air filtration performance by regulating the nano-cobweb/bead-on-string fiber mass ratio and basis weight. The results show that the filtration efficiency and the pressure drop decrease and then increase slightly with the increasing content of bead-on-string fiber. However, the quality factor goes up first, and then down, indicating the beneficial effect of modest bead-on-string fiber content on air filtration property. As the basis weight increases, the growth of filtration efficiency slows down and the pressure drop rises significantly, making the quality factor improve initially and then decline.
