M'zaka zingapo zapitazi, Graphene a Makadi oxidi agwiritsidwa ntchito makamaka kwa madzi osefukira ndi utoto. Komabe, membranes imakhala ndi mapulogalamu osiyanasiyana, monga malonda.
Gulu lofufuzira latsopano latsopano latsopano la ShinShu University laphunzira kugwiritsa ntchito graphene oxide membranes mkaka. Mitundu iyi ya nembaneya imakonda kupanga dothi lochepa (kaboni, "graphene," graphene, oxide mkaka waulere "pa polymer nembanemba.).
Tsekani kwa graphene oxide nembano okhazikika ndi lactose ndi madzi; Siyani mafuta, mapuloteni ndi macromolecles mkaka.
Graphene maxidi a nembanemba ali ndi mwayi wopanga zigawo zonyansa, kotero kuti ntchito yawo yosewerera ikhoza kukhala yabwinoko kuposa ma polimmer membranes. Mitundu yapadera yapadera ndi kapangidwe ka graphene ya oxide imalola kupititsa patsogolo kulowetsedwa kwa lactose ndi madzi, pomwe akubwereka mafuta, mapuloteni ndi michere ina. Chifukwa chake, kapangidwe kake ndi kukoma ndi phindu la mkaka kumatha kusungidwa bwino poyerekeza ndi mafilimu opanga mapulogalamu.
Chifukwa cha mawonekedwe apadera a osanjikaka ndi graphene oxide nembanemba, ndende ya lactose ndi lactose yotupa ndi yokwera kwambiri kuposa ma membraner a nanofines. Pogwiritsa ntchito nembanemba nembanemba yokhala ndi kukula kwa 1 μm monga graphene oxide nembanemba, kuipitsidwa kosasinthika kumayendetsedwa. Izi zimatsogolera pakupanga kwa wosanjikiza wowoneka bwino, zomwe zimapangitsa kuti madzi ayambe kutentha mkaka utatha.
Kuwonetsa momwe amagwirira ntchito bwino kwambiri lactose, ntchito yopainitsa upainiyayi imawonetsa kugwiritsa ntchito kwa graphene ya oxide mu makampani, makamaka mkaka. Njirayi imasunga kuthekera kwakukulu kochotsa shuga ku zakumwa, pomwe zikusakaniza zina, ndikuwonjezera phindu lawo.
Katundu wapamwamba wa antiforming okwanira (monga mkaka) amapanganso chisankho chabwino pa mapulogalamu ena (monga chithandizo chamadzi ndi chithandizo chamankhwala). Gululi limakonzekera kupitiliza kufufuza pulogalamu ya kanema wa oxide.
Ntchitoyi imakhazikika pa kafukufukuyu wakale wa gululo, ndiye kuti kupangidwa kwa graphene ya oxidi Chizindikiro cha membrane chikuwonetsa kukhazikika kwa mankhwala powonjezera graphene, ndikuwonetsa magwiridwe okhazikika patatha masiku asanu ogwira ntchito. Kuphatikiza apo, njira yopumira imalonjeza kwambiri pankhani ya kupsinjika.
