Iintsinga zendalo (ezifana nesilika yesigcawu, iintsiba zezilwanyana, njl. njl.) zithandwa kwintsimi ye-textile ngenxa yesakhiwo sazo esisodwa, kwaye ezinye zezakhiwo zazo kunzima ukuzixelisa ngemicu yokwenziwa kweekhemikhali. amasebe ngamanye adlala indima ebalulekileyo ekukhuseleni ukubanda.Nangona kunjalo, akukho micu enjalo yesakhiwo echazwe kwiinkqubo ze-fiber zokwenziwa kunye neempawu zabo aziwa.

Kutshanje, iqela likanjingalwazi uAndreas Greiner kwidyunivesithi yasebayreuth, eJamani, lidibanise i-coaxial electrospinning ne-triamide fiber self-assembly (ezantsi-phezulu) ukuvelisa ii-polystyrene meso nanofiber wire-nonwovens ezinemilo eyodwa kunye neempawu zemicu yentsiba ye-penguin fluff.

Xa isetyenziselwa ukucoca amaqhekeza e-aerosol ye-0.3 microns, i-nanofiber wirecloth inokusebenza kakuhle kokucoca i-99.8%, ephuculwe kakhulu xa kuthelekiswa ne-electrospun polystyrene nanofiber membrane (ubuchule bokucoca malunga ne-52.6%).

Ukusebenza kokucoca okuphezulu ngokuqhelekileyo kufuna ukusetyenziswa kwamandla aphezulu kunye nokunciphisa uxinzelelo lokulahlekelwa.Nangona kunjalo, kwakungekho ukulahlekelwa kwengcinezelo kunye nokusetyenziswa kwamandla kwinkqubo yokucoca i-villous nanofiber nonwovens kolu vavanyo, oluye lwabangelwa ubukhulu becala kwisakhiwo esikhethekileyo se-electrospun nonwovens.

Ngoko ke, i-electrospun branched fibers ene-supramolecular fibers inika ingcamango entsha yokwakhiwa kwe-mesoporous nonwovens entsha, ene-morphology ekhethekileyo kunye neempawu zokusebenza kwaye inethuba lokusebenzisa i-filtration, i-catalysis kunye nokugcinwa kwamandla.

Iziphumo zophando ezinxulumeneyo zapapashwa kwijenali ye-Advanced Functional Materials phantsi kwesihloko esithi "Mesostructured Nonwovens with Penguin Downy feather-like Morphology -- top-down Combined with bottom-up". Ikhonkco lethisisi: https://doi.org/10.1002 /adfm.201903166
