I-Graphene ikhishwa kusuka ezintweni ze-flake graphite, ikristalu enezinhlangothi ezimbili eyakhiwe ngama-athomu e-carbon anobukhulu obuyi-athomu eyodwa kuphela. Ngenxa yezakhiwo zayo ezinhle kakhulu zokukhanya, zikagesi nezomshini, i-graphene inezinhlelo zokusebenza eziningi. Ngakho-ke ingabe i-flake graphite ne-graphene zihlobene? Umhleli we-graphite we-Furuite olandelayo uhlaziya ubudlelwano phakathii-graphite ye-flakekanye ne-graphene:
1. Indlela yokukhipha i-graphene mass production ayitholakali kakhulu kwi-flake graphite, kodwa kumagesi aqukethe i-carbon njenge-methane ne-acetylene. Nakuba igama linegama elithi graphite, ukukhiqizwa kwe-graphene akutholakali kakhulu kwi-flake graphite. Kunalokho, kutholakala kumagesi aqukethe i-carbon njenge-methane ne-acetylene. Ngisho nendlela yokucwaninga yamanje ikhishwa esihlahleni sesitshalo esikhulayo, futhi manje sekukhona indlela yokukhipha i-graphene ezihlahleni zetiye.
2. Ama-graphite flakes aqukethe izigidi ze-graphene. I-Graphene ikhona ngempela emvelweni. Uma kukhona ubudlelwano phakathi kwe-graphene ne-flake graphite, khona-ke i-graphene ibekwe ungqimba ngengqimba ukuze yakhe ama-graphite flakes. I-Graphene isakhiwo esincane kakhulu esinengqimba eyodwa. Kuthiwa i-millimeter eyodwa ye-flake graphite iqukethe izingqimba ze-graphene ezingaba yizigidi ezintathu, futhi ubuncane be-graphene bungabonakala. Ukuze usebenzise isibonelo esibonakalayo, amagama esiwabhala ephepheni ngamapensela aqukethe izingqimba eziningana noma ezingamashumi ezinkulungwane ze-graphite. ene.
Indlela yokulungisa i-graphene kusuka ku-flake graphite ilula, inezinkinga ezimbalwa kanye nokuqukethwe komoya-mpilo, isivuno esikhulu se-graphene, usayizi omaphakathi, kanye nezindleko eziphansi, futhi ifaneleka ekukhiqizweni kwezimboni okukhulu.
