Ho ea ka phuputso e ncha e phatlalalitsoeng ho 《 Applied Materials Today》, Thepa e ncha e entsoeng ka li-nanofibre tse nyane e ka nkela lintho tse ka bang kotsi tse sebelisoang li-diaper le lihlahisoa tsa bohloeki sebaka kajeno.
Bangoli ba pampiri ena, ba tsoang Setsing sa Theknoloji sa India, ba re boitsebiso ba bona bo bocha bo na le tšusumetso e nyane tikolohong 'me bo bolokehile ho feta seo batho ba se sebelisang kajeno.
Lilemong tse mashome a 'maloa tse fetileng, maleiri a lahloang, li-tampon le lihlahisoa tse ling tsa bohloeki li sebelisitse li-resin tse monyang (SAPs) e le li-amplifier. Lintho tsena li ka monya boima ba tsona ka makhetlo a 'maloa ka har'a metsi; Leleiri le tloaelehileng le ka monya boima ba lona ka makhetlo a 30 maro a 'mele. Empa thepa ha e senyehe: tlas'a maemo a matle, leleiri le ka nka lilemo tse 500 ho senyeha. Li-SAP li ka boela tsa baka mathata a bophelo bo botle joalo ka chefo ea shock syndrome, 'me li ile tsa thibeloa ho sebelisa li-tampon lilemong tsa bo-1980.
Thepa e ncha e entsoeng ka li-nanofiber tsa cellulose acetate tsa electrospun ha e na le e 'ngoe ea mathata ana. Phuputsong ea bona, sehlopha sa lipatlisiso se hlahlobile thepa eo, eo ba lumelang hore e ka nkela SAP sebaka e sebelisoang hona joale lihlahisoa tsa bohloeki ba basali.
"Ho bohlokoa ho hlahisa mekhoa e meng e sireletsehileng ho feta lihlahisoa tse fumanehang khoebong, e ka bakang chefo ea shock syndrome le matšoao a mang," ho boletse Ngaka Chandra Sharma, mongoli ea tsamaisanang le eena oa pampiri ena. Re fana ka maikutlo a ho felisa lintho tse kotsi tse sebelisoang lihlahisoa tse fumanehang khoebong hona joale le li-resin tse sa boleng tse monyang lintho tse phelang motheong oa ho se fetole ts'ebetso ea sehlahisoa kapa esita le ho ntlafatsa ho monya metsi le boiketlo ba sona.
Li-nanofiber ke likhoele tse telele le tse tšesaane tse hlahisoang ke ho potoloha ka motlakase. Ka lebaka la sebaka sa tsona se seholo sa bokaholimo, bafuputsi ba lumela hore li monya habonolo ho feta thepa e teng. Thepa e sebelisoang li-tampon tse rekisoang e entsoe ka likhoele tse bataletseng, tse tlamiloeng ka lebanta tse ka bang 30 microns ka morao. Li-nanofiber, ka lehlakoreng le leng, li tenya ka li-nanometer tse 150, li tšesaane ka makhetlo a 200 ho feta thepa ea hona joale. Thepa e phutholohile ho feta e sebelisoang lihlahisoa tse teng 'me e siea masala a fokolang kamora ho sebelisoa.
Thepa ea nanofiber le eona e na le masoba (ho feta 90%) ha e bapisoa le ea setso (80%), kahoo e monya haholoanyane. Ntlha e 'ngoe e ka hlahisoa: ho sebelisoa liteko tsa saline le tsa moroto oa maiketsetso, likhoele tsa masela tse sa fetoheng ka motlakase li monya haholo ho feta lihlahisoa tse fumanehang khoebong. Ba boetse ba lekile mefuta e 'meli ea thepa ea nanofiber ka li-SAP, 'me liphetho li bontšitse hore nanofiber e le 'ngoe e sebelitse hamolemo.
"Liphetho tsa rona li bontša hore li-nanofiber tsa masela a electrostatic li sebetsa hantle ho feta lihlahisoa tsa bohloeki tse fumanehang khoebong mabapi le ho monya metsi le boiketlo, 'me re lumela hore ke khetho e ntle ea ho nkela lintho tse kotsi tse sebelisoang hona joale sebaka," ho boletse Ngaka Sharma. "Re tšepa ho ba le tšusumetso e ntle bophelong ba batho le tikolohong ka tšebeliso e sireletsehileng le ho lahla lihlahisoa tsa bohloeki.
