Graphene ndi chinthu chodziwika bwino cha inorganic posachedwapa, ndipo chalandira chidwi chochulukirapo pama transistors, mabatire, ma capacitor, polymer nanosynthesis, ndi kupatukana kwa membrane.Zomwe zitha kukhala zatsopano za membrane zitha kukhala m'badwo wotsatira wa zinthu zazikuluzikulu za membrane.
Makhalidwe a Graphene Oxide
Graphene oxide (GO) ndi chisa cha uchi chopangidwa ndi gawo limodzi la maatomu a carbon.Mapangidwe ake amapangidwa makamaka ndi maatomu a carbon ndi magulu ogwirira ntchito okhala ndi mpweya wa polar.GO ndi chifukwa cha mtundu wamagulu ogwira ntchito omwe ali ndi okosijeni.Ndipo kugawidwa kosadziwika bwino kumapangitsa kuti mamolekyu ake akhale otsutsana.Pakati pawo, mawonekedwe a Lerf-Klinowski amadziwika kwambiri, ndipo zimatsimikiziridwa kuti pali magulu atatu ogwira ntchito mu GO, omwe ndi magulu a hydroxyl ndi epoxy omwe ali pamtunda, ndi omwe ali m'mphepete.carboxyl.
GO ili ndi mawonekedwe amitundu iwiri ofanana ndi graphene.Kusiyana kwake ndikuti GO imayambitsa magulu ambiri ogwira ntchito omwe ali ndi mpweya wa polar pamwamba pa carbon skeleton chifukwa cha okosijeni, monga -O-, -COOH, -OH, etc. Kukhalapo kwa magulu ogwira ntchito kumawonjezera zovuta za ndondomeko ya GO.Zigawo za GO zimalumikizidwa ndi kuchuluka kwa ma hydrogen bond, ndipo mawonekedwe amitundu iwiri amalumikizidwa ndi zomangira zolimba, zomwe zimapangitsa kuti ikhale ya hydrophilic kwambiri.GO poyamba inkawoneka ngati chinthu cha hydrophilic, koma GO kwenikweni ndi amphiphilic, kusonyeza kusintha kuchokera ku hydrophilic kupita ku hydrophobic kuchokera m'mphepete kupita pakati.Mapangidwe apadera a GO amaupatsa malo apamwamba kwambiri, ma thermodynamics apadera Ili ndi tanthauzo labwino lofufuza komanso chiyembekezo chogwiritsa ntchito pazachilengedwe, zamankhwala, ndi zida.
Masiku angapo apitawo, nyuzipepala yapamwamba yapadziko lonse lapansi "Nature" inafalitsa msonkhano wa "Ion sieving ndi ma cations omwe amawongolera kusiyana pakati pa mafilimu a graphene oxide".Kafukufukuyu akuwonetsa ndikuzindikira kuwongolera bwino kwa nembanemba za graphene pogwiritsa ntchito ma hydrated ayoni, kuwonetsa sieving yabwino kwambiri ya ion ndi kuchotsa mchere m'madzi a m'nyanja.ntchito.
Malinga ndi makampaniwa, dziko langa lasamalira kafukufuku ndi chitukuko m'munda wa graphene kale.Kuyambira 2012, dziko langa lapereka zoposa 10 mfundo zokhudzana ndi graphene.Mu 2015, woyamba dziko mlingo mapulogalamu chikalata "Maganizidwe angapo pa Kufulumizitsa luso ndi Development wa Makampani Graphene" akufuna kumanga makampani graphene mu makampani kutsogolera, ndi kupanga wathunthu graphene makampani dongosolo ndi 2020. A mndandanda wa zikalata monga monga 13th 5-year Plan yaphatikiza graphene m'munda wa zida zatsopano zomwe zapangidwa mwamphamvu.Bungweli limaneneratu kuti msika wonse wa msika wa graphene wa dziko langa ukuyembekezeka kupitilira 10 biliyoni mu 2017. Kukula kwamakampani a graphene kukukulirakulira, ndipo makampani ogwirizana nawo akuyembekezeka kupindula.
