Graphene waxaa laga saaraa walxaha flake graphite, oo ah kiristaal laba-geesood ah oo ka kooban atamka kaarboon oo dhumucdiisu tahay hal atomiik oo keliya. Sababtoo ah sifooyinkeeda indhaha, korontada iyo farsamada ee aadka u fiican, graphene waxay leedahay codsiyo badan. Haddaba ma isku xiran yihiin flake graphite iyo graphene? Tifaftiraha garaafka Furuite ee soo socda wuxuu falanqeynayaa xiriirka ka dhexeeyagraphite dabacsaniyo graphene:
1. Habka soo saarista ee wax soo saarka tirada graphene inta badan lagama helo graphite flake, laakiin waxaa laga helaa gaasaska kaarboonka ku jira sida methane iyo acetylene. Inkasta oo magacu leeyahay ereyga graphite, soo saarista graphene inta badan kama soo baxdo graphite flake. Taa beddelkeeda, waxaa laga helaa gaasaska kaarboonka ku jira sida methane iyo acetylene. Xitaa habka cilmi-baarista ee hadda jira waxaa laga soo saaraa geedka dhirta koraya, haddana waxaa jira hab lagu soo saaro graphene geedaha shaaha.
2. Jajabyada Graphite waxay ka kooban yihiin malaayiin graphene ah. Graphene dhab ahaantii way ka jirtaa dabeecadda. Haddii uu jiro xiriir u dhexeeya graphene iyo flake graphite, markaa graphene waxaa lagu dul saaraa lakab lakab si loo sameeyo jajabyada graphite. Graphene waa qaab-dhismeed hal lakab ah oo aad u yar. Waxaa la sheegay in hal millimitir oo flake graphite ah uu ka kooban yahay qiyaastii 3 milyan oo lakab oo graphene ah, waxaana la arki karaa quruxda graphene. Si loo isticmaalo tusaale muuqaal ah, ereyada aan ku qorno warqad qalin leh waxay ka kooban yihiin dhowr ama tobanaan kun oo lakab oo graphite ah. ene.
Habka loo diyaariyo graphene-ka laga soo saaro flake graphite waa mid fudud, cillado yar iyo oksijiin yar, wax soo saar graphene oo sarreeya, cabbir dhexdhexaad ah, iyo kharash yar, waana mid ku habboon wax soo saarka warshadaha ee baaxadda weyn.
