Isingeniso se-Graphene
I-graphene inezinhlangothi ezimbili (2D) uhlobo lwekhabhoni ehlelwe ungqimba olulodwa lwama-athomu endaweni ephindaphindayo eyi-hexagonal. Kwaqala kwahlukaniswa phakathi 2004 ngu-Andre Geim noKonstantin Novoselov eNyuvesi yaseManchester, abaklonyeliswe ngeNobel Prize in Physics in 2010 ngokuhlolwa kwabo okubalulekile. I-graphene empeleni iyimeshi yezinyosi zesikali se-athomu yama-athomu ekhabhoni, okwenza kube yilungu lomndeni wesakhiwo esiphelele, okuhlanganisa ne-graphite, amalahle, ama-carbon nanotubes, kanye nama- fullerenes (ama-buckyballs).
Izici ze-graphene
Amandla: I-graphene ingenye yezinto eziqine kakhulu ezaziwayo, ngamandla aqinile nxazonke 130 ama-gigapascals (I-GPa), elinamandla kunedayimane futhi liqine kakhulu kunensimbi.
Ukuvumelana nezimo: Naphezu kwamandla ayo, I-graphene nayo iyagobeka futhi ingagotshwa noma igoqwe ngaphandle kokuphuka.
I-Conductivity: Kuyi-conductor kagesi esezingeni eliphezulu, nokuhamba kwe-electron ngaphezulu 200 izikhathi ezinkulu kune-silicon.
I-Thermal Conductivity: I-graphene ine-conductivity ephezulu kakhulu ye-thermal, okusho ukuthi ingaphatha ukushisa kahle kakhulu.
Ukungafihli: I-graphene cishe isobala ngokuphelele, ukwamukela kuphela 2.3% yokukhanya, okwenza kube ilungele ukusetshenziswa electronics transparent.
Ukuzinza Kwamakhemikhali: Iqinile kumakhemikhali futhi ingamelana ne-oxidation emoyeni, okwandisa ukuqina kwayo.
Indawo Ephezulu Ephezulu: Igramu yegraphene inendawo engaphezulu efika ku 2630 square metres, okuwusizo ezinhlelweni ezidinga izindawo ezinkulu.
Izicelo ze-Graphene
Ezogesi: I-graphene ingakwazi ukuguqula izinto ze-elekthronikhi ngenxa yokuhamba kwayo okuphezulu kwe-electron nokuba sobala, ukuyenza ifanele izikrini zokuthinta, amaseli we-photovoltaic, kanye nemishini ye-elekthronikhi enemvamisa ephezulu.
Isitoreji Amandla: Ingakwazi ukuthuthukisa ukusebenza kwamabhethri nama-supercapacitor ngenxa yendawo yayo ephezulu kanye nokuhamba.
Izinto Ezihlanganisiwe: Ngokungeza i-graphene kumapulasitiki, izinsimbi, noma izitsha zobumba, izinhlanganisela eziwumphumela zingaba nomshini othuthukisiwe, ezishisayo, kanye nezakhiwo zikagesi.
Ubunjiniyela be-Biomedical: I-biocompatibility ye-graphene nekhono lokuthwala izidakamizwa kuyenza isebenziseke ezinhlelweni zokulethwa kwezidakamizwa nobunjiniyela bezicubu.
Ukuhlanzwa kwamanzi: Ulwelwesi olususelwa ku-graphene lungasefa ukungcola emanzini, kuhlanganise nosawoti, amagciwane, kanye namagciwane.
Izinzwa: Izinzwa ze-graphene zingathola inani elincane lamagesi noma ama-biomolecules, ukubenza babe wusizo ekuqaphelweni kwemvelo nasekuxilongweni kwezokwelapha.
I-Flexible Electronics: Ukuguquguquka kwayo kanye nokusebenza kwayo kuyenza ifaneleke kumadivayisi agqokekayo kanye nezibonisi eziguqukayo.
Iphrofayela Yenkampani
I-Graphene Aerogels ingumphakeli othembekile wezinto zamakhemikhali zomhlaba wonke & umkhiqizi onolwazi olungaphezu kweminyaka eyi-12 ekunikezeni igraphene yekhwalithi ephezulu kakhulu, i-airgel kanye nemikhiqizo ehlobene.
Le nkampani inomnyango wezobuchwepheshe oqeqeshiwe kanye noMnyango Wokuqondisa Ikhwalithi, ilabhorethri efakwe kahle, futhi ifakwe imishini yokuhlola ethuthukisiwe kanye nesikhungo senkonzo yamakhasimende ngemva kokuthengisa.
Uma ufuna i-graphene yekhwalithi ephezulu, i-airgel kanye nemikhiqizo ehlobene, sicela ukhululeke ukuxhumana nathi noma uchofoze imikhiqizo edingekayo ukuze uthumele uphenyo.

Imibuzo Evame Ukubuzwa mayelana ne-Graphene
Ikhiqizwa kanjani i-graphene?
I-graphene ingakhiqizwa ngezindlela eziningi, kuhlanganisa nokucwecwa kwemishini (ukuxebula izingqimba zegraphite), ukufakwa komhwamuko wamakhemikhali (I-CVD), kanye nokunciphisa amakhemikhali e-graphene oxide.
Ingabe i-graphene inobuthi?
Ucwaningo lwamanje luphakamisa ukuthi i-graphene ingaba nezinkinga ezithile zobuthi, ikakhulukazi uma uhogeliwe, kodwa ucwaningo olwengeziwe luyadingeka ukuze kuqondwe ngokugcwele imithelela yayo yezempilo engaba khona.
Ingabe i-graphene ingakhiqizwa ngobuningi?
Yebo, Izindlela ezifana ne-CVD zivumela ukukhiqizwa kwe-graphene ngezinga elikhulu, nakuba ukuzuza ikhwalithi efanayo kanye namashidi wendawo enkulu kuhlala kuyinselele.
Ziyini izindleko ze-graphene?
Izindleko ziyahlukahluka kuye ngendlela yokukhiqiza kanye nobumsulwa obudingekayo, kodwa amanani ehle kakhulu njengoba izindlela zokukhiqiza sezithuthukile.
Ingabe i-graphene inezakhiwo kazibuthe?
I-graphene ehlanzekile ngokwayo ayiwona kazibuthe, kodwa ingashintshwa ukuze ibonise izakhiwo kazibuthe ngokusebenzisa i-doping noma imiphumela yokuba seduze nezinto zikazibuthe.
