Zvinoenderana nechidzidzo chitsva chakaburitswa mu 《Applied Materials Nhasi》, Chinhu chitsva chakagadzirwa kubva mudiki nanofibres chinogona kutsiva zvinhu zvinogona kukuvadza zvinoshandiswa mumanapukeni uye zvigadzirwa zvehutsanana nhasi.
Vanyori vebepa iri, vekuIndia Institute of Technology, vanoti zvinhu zvavo zvitsva zvine chekuita nenharaunda uye zvakachengeteka pane zviri kushandiswa nevanhu nhasi.
Mumakumi mashoma emakore adarika, manapukeni anoraswa, matamponi uye zvimwe zvigadzirwa zvehutsanana zvakashandisa maabsorbent resins (SAPs) sezvinwiwa. Zvinhu izvi zvinogona kutora kakawanda uremu hwazvo mumvura;Avhareji yenapukeni inogona kutora ka30 huremu hwayo mumvura dzemuviri.Asi izvo zvinhu hazvisi biodegrade: pasi pemamiriro ezvinhu akanaka, diaper inogona kutora makore anosvika mazana mashanu kuti adzikise.MaSAP anogonawo kukonzera matambudziko ehutano senge toxic shock syndrome, uye akarambidzwa kubva kumatamponi muma1980.
Chinhu chitsva chakagadzirwa kubva ku electrospun cellulose acetate nanofibers haina chimwe chezvipingamupinyi izvi.Muchidzidzo chavo, boka rekutsvagisa rakaongorora zvinhu, izvo zvavanotenda kuti zvinogona kutsiva maSAP anoshandiswa pari zvino muzvigadzirwa zvehutsanana hwevakadzi.
"Zvakakosha kugadzira dzimwe nzira dzakachengeteka kune zvigadzirwa zvinotengeswa, izvo zvinogona kukonzera toxic shock syndrome uye zvimwe zviratidzo," Dr Chandra Sharma, anowirirana munyori webepa.Isu tinokurudzira kubvisa zvinhu zvinokuvadza zvinoshandiswa mune zvazvino zvigadzirwa zvinotengeswa uye zvisiri-biodegradable superabsorbent resins pahwaro hwekusachinja mashandiro echigadzirwa kana kunyange kuvandudza kutora kwayo uye kunyaradza kwemvura.
Nanofibers marefu uye matete fiber anogadzirwa ne electrospinning.Nekuda kwenzvimbo yavo yakakura, vaongorori vanotenda kuti vanonyura kupfuura zvinhu zviripo.Izvo zvinhu zvinoshandiswa mumatamponi anotengeswa anogadzirwa neflat, mabhandi fibers anenge 30 microns kumashure.Nanofibers, nekusiyana, dzakakora 150 nanometers, dzakatetepa ka200 pane zvemazuva ano.Nyaya yacho yakasununguka kupfuura iyo inoshandiswa mune zvigadzirwa zviripo uye inosiya zvishoma zvakasara mushure mekushandisa.
Iyo nanofiber zvinhu zvakare ine porous (inopfuura 90%) maringe neyakajairwa (80%), saka inonyudza zvakanyanya.Imwe pfungwa inogona kuitwa: kushandisa saline uye synthetic weti bvunzo, electrostatic textile fibers inonyudza kupfuura zvigadzirwa zvinotengeswa.Vakaedzawo shanduro mbiri dze nanofibre zvinhu neSAPs, uye mhedzisiro yakaratidza kuti nanofibre yega yakashanda zvirinani.
"Zvigumisiro zvedu zvinoratidza kuti electrostatic textile nanofibers inoita zviri nani pane zvigadzirwa zvehutsanana zvinowanikwa mune zvekutengesa maererano nekunyura kwemvura uye kunyaradza, uye tinotenda kuti ivo vakakodzera kutsiva zvinhu zvinokuvadza zviri kushandiswa ikozvino," Dr. Sharma akadaro.“Tine tarisiro yekuve nemhedzisiro yakanaka pahutano hwevanhu pamwe nenharaunda kuburikidza nekushandisa kwakachengeteka uye kuraswa kwehutsanana.
