Wahi a kahi noiʻi hou i paʻi ʻia ma 《 Applied Materials Today 》, Hiki i kahi mea hou i hana ʻia mai nā nanofibers liʻiliʻi ke hoʻololi i nā mea ʻino i hoʻohana ʻia i nā diapers a me nā huahana maʻemaʻe i kēia lā.
Wahi a nā mea kākau o ka pepa, mai ka Indian Institute of Technology, ʻaʻole liʻiliʻi ka hopena o kā lākou mea hou i ke kaiapuni a ʻoi aku ka palekana ma mua o ka mea e hoʻohana ai nā kānaka i kēia lā.
I loko o nā makahiki i hala iho nei, ua hoʻohana nā diapers i hoʻokuʻu ʻia, nā tampons a me nā mea hoʻomaʻemaʻe ʻē aʻe i nā resins absorbent (SAPs) ma ke ʻano he absorbers. Hiki i kēia mau mea ke komo pinepine i ko lākou kaumaha i ka wai;Hiki i ka diaper maʻamau ke komo i 30 manawa o kona kaumaha i loko o nā wai kino.Akā ʻaʻole biodegrade ka mea: ma lalo o nā kūlana kūpono, hiki i kahi diaper ke lawe i 500 mau makahiki e hoʻohaʻahaʻa.Hiki i nā SAP ke hana i nā pilikia olakino e like me ka toxic shock syndrome, a ua pāpā ʻia lākou mai nā tampons i nā makahiki 1980.
ʻO kahi mea hou i hana ʻia mai ka electrospun cellulose acetate nanofibers ʻaʻohe o kēia mau drawbacks.I kā lākou noiʻi ʻana, ua loiloi ka hui noiʻi i ka mea, a lākou i manaʻoʻiʻo ai hiki ke hoʻololi i nā SAP i hoʻohana ʻia i nā huahana hoʻomaʻemaʻe wahine.
"He mea nui ka hoʻomohala ʻana i nā mea ʻokoʻa palekana i nā huahana i loaʻa i ke kālepa, hiki ke hoʻoulu i ka maʻi toxic shock a me nā hōʻailona ʻē aʻe," ʻo Dr Chandra Sharma, ka mea kākau o ka pepa.Manaʻo mākou e hoʻopau i nā mea ʻino i hoʻohana ʻia i nā huahana i kūʻai ʻia i kēia manawa a me nā resins superabsorbent non-biodegradable ma ke kumu o ka hoʻololi ʻole ʻana i ka hana o ka huahana a i ʻole ka hoʻomaikaʻi ʻana i ka wai a me ka hōʻoluʻolu.
ʻO nā nanofibers he mau fiber lōʻihi a lahilahi i hana ʻia e ka electrospinning.Ma muli o ko lākou ʻāpana ʻili nui, manaʻo ka poʻe noiʻi ua ʻoi aku ka ʻoi aku o lākou ma mua o nā mea i loaʻa.ʻO nā mea i hoʻohana ʻia i nā pāpili i loaʻa i ke kūʻai aku, ua hana ʻia me nā fiber paʻa paʻa ma kahi o 30 microns ma hope.ʻO nā nanofibers, ma ka ʻokoʻa, he 150 nanometers ka mānoanoa, 200 manawa ʻoi aku ka lahilahi ma mua o nā mea o kēia manawa.ʻOi aku ka ʻoluʻolu o ka mea ma mua o nā mea i hoʻohana ʻia i nā huahana i loaʻa a waiho i ke koena liʻiliʻi ma hope o ka hoʻohana ʻana.
He porous ka mea nanofiber (ma luna o 90%) me ka mea maʻamau (80%), no laila ua ʻoi aku ka absorbent.Hiki ke hana hou ʻia: me ka hoʻohana ʻana i ka saline a me ka hoʻāʻo ʻana i ka mimi synthetic, ʻoi aku ka maikaʻi o nā fiber textile electrostatic ma mua o nā huahana i kūʻai ʻia.Ua ho'āʻo pū lākou i ʻelua mau mana o ka mea nanofibre me nā SAP, a ua hōʻike nā hopena i ʻoi aku ka maikaʻi o ka nanofibre wale nō.
"Ke hōʻike nei kā mākou mau hopena i ka hana maikaʻi ʻana o nā nanofibers textile electrostatic ma mua o nā huahana maʻemaʻe i kūʻai ʻia ma ke ʻano o ka lawe ʻana i ka wai a me ka hōʻoluʻolu, a ke manaʻoʻiʻo nei mākou he moho maikaʻi lākou e pani i nā mea ʻino i hoʻohana ʻia i kēia manawa," wahi a Dr. Sharma."Manaʻo mākou e loaʻa ka hopena maikaʻi i ke olakino kanaka a me ke kaiapuni ma o ka hoʻohana palekana a me ka hoʻokuʻu ʻana i nā huahana maʻemaʻe.
