Graphene ndi galasi la magawo awiri lopangidwa ndi maatomu a kaboni, atomu imodzi yokha yokhuthala, yochotsedwa ku zinthu za graphite ya flake. Graphene ili ndi ntchito zambiri chifukwa cha mphamvu zake zabwino kwambiri mu optics, magetsi ndi makina. Ndiye kodi pali ubale pakati pa graphite ya flake ndi graphene? Mndandanda waung'ono wotsatira wa Kusanthula ubale pakati pa graphite ya flake ndi graphene:
Graphite yopyapyala
1. Njira yochotsera graphene yambiri siichokera ku flake graphite, koma kuchokera ku mpweya wokhala ndi kaboni monga methane ndi acetylene. Ngakhale dzinali likupezeka, kupanga graphene sikuchokera ku flake graphite. Imapangidwa kuchokera ku mpweya wokhala ndi kaboni monga methane ndi acetylene, ndipo ngakhale pano pali njira zochotsera graphene kuchokera ku zomera zomwe zikukula, ndipo tsopano pali njira zochotsera graphene kuchokera ku mitengo ya tiyi.
2. Graphite ya flake ili ndi ma graphene mamiliyoni ambiri. Graphite ilipodi m'chilengedwe, ngati ubale pakati pa graphene ndi graphite ya flake ndi graphite ya flake, graphene ndi kapangidwe kakang'ono kwambiri ka monolayer. Milimita imodzi ya graphite ya flake akuti ili ndi ma graphene pafupifupi mamiliyoni atatu, ndipo kusalala kwa graphene kungawonekere, pogwiritsa ntchito chitsanzo chojambula, tikamalemba mawu papepala ndi pensulo, pamakhala ma graphene angapo kapena makumi ambiri.
Njira yokonzekera graphene kuchokera ku flake graphite ndi yosavuta, yokhala ndi zolakwika zochepa komanso mpweya wochepa, graphene yochuluka, kukula kwapakati, komanso mtengo wotsika, zomwe ndizoyenera kupanga mafakitale akuluakulu.
