M'zaka zingapo zapitazi, nembanemba za graphene oxide zakhala zikugwiritsidwa ntchito kwambiri pochotsa mchere m'madzi a m'nyanja ndi kulekanitsa utoto.Komabe, nembanemba imakhala ndi ntchito zosiyanasiyana, monga makampani azakudya.
Gulu lofufuza kuchokera ku Global Aquatic Innovation Center ya Shinshu University laphunzira kagwiritsidwe ntchito ka nembanemba za graphene oxide mu mkaka.Nembanemba yamtunduwu nthawi zambiri imapanga dothi lowundana (carbon, "Graphene oxide nembanemba za mkaka wopanda lactose" pa nembanemba ya polima. ) .
Tsekani nembanemba ya graphene oxide yomwe imalowetsedwa ndi lactose ndi madzi;kusiya mafuta, mapuloteni ndi macromolecules mu mkaka.
Ma nembanemba a graphene oxide ali ndi mwayi wopanga zigawo za porous fouling, kotero kusefera kwawo kumatha kusamalidwa bwino kuposa ma nembanemba a polima ogulitsa.Kapangidwe kake kapadera ka graphene oxide nembanemba kaphatikizidwe ka graphene oxide kumathandizira kulowa kwa lactose ndi madzi, ndikuthamangitsa mafuta, mapuloteni ndi mchere.Chifukwa chake, kapangidwe kake, kukoma komanso thanzi la mkaka zitha kusungidwa bwino poyerekeza ndi mafilimu a polima amalonda.
Chifukwa cha mawonekedwe apadera a porous fouling wosanjikiza ndi nembanemba ya graphene oxide, kuchuluka kwa lactose ndi lactose permeation flux ndikwambiri kuposa komwe kumapangidwa ndi nanofiltration nembanemba.Pogwiritsa ntchito nembanemba yothandizira yokhala ndi pore kukula kwa 1 μm ngati nembanemba ya graphene oxide, kuipitsidwa kosasinthika kumasinthidwa.Izi zimapangitsa kuti pakhale porous fouling wosanjikiza, zomwe zimathandiza kuti madzi ayambe kusungunuka pambuyo poti mkaka utasefedwa.
Kuwonetsa kachitidwe kake kabwino ka antifouling komanso kusankha kwakukulu kwa lactose, ntchito yochita upainiyayi ikuwonetsa kugwiritsa ntchito nembanemba za graphene oxide m'makampani azakudya, makamaka makampani a mkaka.Njirayi imakhalabe ndi kuthekera kwakukulu kochotsa shuga ku zakumwa, ndikusunga zosakaniza zina, motero kumawonjezera phindu lawo lazakudya.
Kuchuluka kwa antifouling kwa organic-rich solutions (monga mkaka) kumapangitsanso kukhala chisankho choyenera pazinthu zina (monga madzi otayira ndi ntchito zachipatala).Gululi likukonzekera kupitiliza kufufuza kagwiritsidwe ntchito ka filimu ya graphene oxide.
Ntchitoyi imachokera ku zotsatira za kafukufuku wam'mbuyo wa gululi, zomwe ndi kupanga ma nembanemba opopera a graphene oxide ("NaCl Yogwira Ntchito komanso kukana utoto wa hybrid graphene oxide/graphene layered nembanes") pochotsa madzi am'nyanja muzachilengedwe za nanotechnology.Nembanemba imawonetsa kukhazikika kwamankhwala powonjezera magawo ochepa a graphene, pomwe ikuwonetsa kusefera kokhazikika pakatha masiku asanu akugwira ntchito.Kuphatikiza apo, njira yoyikapo utsi ndiyodalirika kwambiri pankhani ya scalability.
