I-Graphene iyikristalu enezinhlangothi ezimbili eyenziwe ngama-athomu e-carbon. I-athomu elilodwa kuphela elijiyile, elikhishwe ezintweni ze-graphite ezigobile. I-Graphene inezinhlobo eziningi zokusetshenziswa ngenxa yezakhiwo zayo ezinhle kakhulu ku-optics, ugesi kanye ne-mechanics. Ngakho-ke ingabe kukhona ubudlelwano phakathi kwe-graphite ezigobile kanye ne-graphene? Uchungechunge oluncane olulandelayo lokuhlaziywa kobudlelwano phakathi kwe-graphite ezigobile kanye ne-graphene:
I-graphite ye-Flake
1. Indlela yokukhipha i-graphene ngobuningi ayitholakali kakhulu kwi-flake graphite, kodwa kumagesi aqukethe i-carbon njenge-methane ne-acetylene. Naphezu kwegama layo, ukukhiqizwa kwe-graphene akuveli kakhulu kwi-flake graphite. Kwenziwe ngamagesi aqukethe i-carbon njenge-methane ne-acetylene, futhi ngisho namanje kunezindlela zokukhipha i-graphene ezitshalweni ezikhulayo, futhi manje kunezindlela zokukhipha i-graphene ezihlahleni zetiye.
2. I-graphite ye-Flake iqukethe izigidi ze-graphene. I-Graphene ikhona ngempela emvelweni, uma ubuhlobo phakathi kwe-graphene ne-flake graphite, khona-ke ungqimba lwe-graphene ngengqimba luyi-flake graphite, i-graphene isakhiwo esincane kakhulu se-monolayer. Kuthiwa i-millimeter eyodwa ye-flake graphite iqukethe izingqimba ze-graphene ezingaba yizigidi ezintathu, futhi ubuncane be-graphene bungabonakala, ukusebenzisa isibonelo esicacile, lapho sibhala amagama ephepheni ngepensela, kunezingqimba eziningana noma ezingamashumi ezinkulungwane ze-graphene.
Indlela yokulungiselela i-graphene kusuka ku-flake graphite ilula, inezinkinga ezincane kanye nokuqukethwe komoya-mpilo, isivuno esikhulu se-graphene, usayizi omaphakathi, kanye nezindleko eziphansi, ezifanele ukukhiqizwa kwezimboni ezinkulu.
