Ubudlelwane phakathi kwe-flake graphite kunye ne-graphene

I-Graphene yikristale enamacala amabini eyenziwe ngeeathom zekhabhoni, i-athomu enye kuphela etyebileyo, isuswe kwizinto ze-graphite ezithambileyo. I-Graphene ineendlela ezininzi zokusetyenziswa ngenxa yeempawu zayo ezintle kwi-optics, umbane kunye ne-mechanics. Ngaba kukho ubudlelwane phakathi kwe-graphite ethambileyo kunye ne-graphene? Olu luhlu luncinci lulandelayo lohlalutyo lobudlelwane phakathi kwe-graphite ethambileyo kunye ne-graphene:

I-graphite ye-Flake

1. Indlela yokukhupha i-graphene ngobuninzi ayifumaneki kakhulu kwi-flake graphite, kodwa kwiigesi ezine-carbon ezifana ne-methane kunye ne-acetylene. Nangona libizwa njalo, imveliso ye-graphene ayiveli kwi-flake graphite. Yenziwe ngeegesi ezine-carbon ezifana ne-methane kunye ne-acetylene, kwaye nangoku kukho iindlela zokukhupha i-graphene kwizityalo ezikhulayo, kwaye ngoku kukho iindlela zokukhupha i-graphene kwimithi yeti.

2. I-Flake graphite inezigidi ze-graphene. I-Graphene ikhona kwindalo, ukuba ubudlelwane phakathi kwe-graphene kunye ne-flake graphite, ngoko i-graphene umaleko ngomaleko yi-flake graphite, i-graphene sisakhiwo esincinci kakhulu se-monolayer. Kuthiwa i-millimeter enye ye-flake graphite iqulethe malunga nezigidi ezintathu ze-graphene, kwaye ubuncinci be-graphene bunokubonwa, ukusebenzisa umzekelo wemizobo, xa sibhala amagama ephepheni ngepensile, kukho amashumi amawaka ee-layer ze-graphene.

Indlela yokulungisa i-graphene evela kwi-flake graphite ilula, ineziphene ezincinci kunye nomxholo weoksijini, isivuno esiphezulu se-graphene, ubungakanani obuphakathi, kunye neendleko eziphantsi, ezifanelekileyo kwimveliso yemizi-mveliso emikhulu.
