I-Graphene ikhutshwa kwizinto ze-flake graphite, ikristale enamacala amabini eyenziwe zii-athomu zekhabhoni ezinobukhulu obunye be-athomu. Ngenxa yeempawu zayo ezintle zokukhanya, zombane kunye nezoomatshini, i-graphene ineendlela ezahlukeneyo zokusetyenziswa. Ngoko ke ingaba i-flake graphite kunye ne-graphene zinxulumene? Umhleli we-graphite we-Furuite olandelayo uhlalutya ubudlelwane phakathiigrafayithi ye-flakekunye negraphene:
1. Indlela yokukhupha i-graphene mass production ayifumaneki kakhulu kwi-flake graphite, kodwa kwiigesi ezine-carbon ezifana ne-methane kunye ne-acetylene. Nangona eli gama linegama elithi graphite, imveliso ye-graphene ayifumaneki kakhulu kwi-flake graphite. Endaweni yoko, ifumaneka kwiigesi ezine-carbon ezifana ne-methane kunye ne-acetylene. Kwanendlela yophando yangoku ikhutshwa kumthi wesityalo okhulayo, kwaye ngoku kukho indlela yokukhupha i-graphene kwimithi yeti.
2. Iiflake zegrafiti ziqulathe izigidi zeegraphene. I-Graphene ikhona kwindalo. Ukuba kukho ubudlelwane phakathi kwe-graphene kunye ne-flake graphite, i-graphene ibekwe ngaphezulu komaleko ngomnyeleko ukuze yenze iiflake zegrafiti. I-Graphene sisakhiwo esincinci kakhulu esinomaleko omnye. Kuthiwa i-millimeter enye ye-flake graphite iqulathe malunga nezigidi ezi-3 zeelake zegrafiti, kwaye ubuncinci be-graphene bunokubonwa. Ukusebenzisa umzekelo obonakalayo, amagama esiwabhala ephepheni ngeepensile aqulathe amashumi amawaka eeleke zegrafiti. ene.
Indlela yokulungisa i-graphene nge-flake graphite ilula, ineziphene ezimbalwa kunye nomxholo we-oksijini, isivuno esiphezulu se-graphene, ubungakanani obuphakathi, kunye neendleko eziphantsi, kwaye ifanelekile kwimveliso yemizi-mveliso emikhulu.
