Ubale pakati pa flake graphite ndi graphene

Graphene ndi exfoliated kuchokera ku flake graphite material, kristalo wa mbali ziwiri wopangidwa ndi maatomu a carbon omwe ndi atomiki imodzi yokha. Chifukwa cha mawonekedwe ake owoneka bwino, magetsi ndi makina, graphene ili ndi ntchito zambiri. Ndiye kodi flake graphite ndi graphene zimagwirizana? Mkonzi wotsatira wa Furuite graphite amasanthula ubale womwe ulipo pakatichithunzi cha graphitendi graphene:

1. Njira yochotsera graphene yochuluka siimapezeka makamaka kuchokera ku flake graphite, koma kuchokera ku mpweya wokhala ndi mpweya monga methane ndi acetylene. Ngakhale kuti dzinali lili ndi mawu akuti graphite, kupanga graphene sikuchokera ku flake graphite. M'malo mwake, amachokera ku mpweya wokhala ndi mpweya monga methane ndi acetylene. Ngakhale njira yofufuzira yamakono imachotsedwa ku mtengo wa zomera zomwe zikukula, ndipo tsopano pali njira yochotsera graphene ku mitengo ya tiyi.
2. Ma graphite flakes ali ndi mamiliyoni a graphene. Graphene ilipo m'chilengedwe. Ngati pali ubale pakati pa graphene ndi flake graphite, ndiye graphene ndi superimposed wosanjikiza ndi wosanjikiza kupanga graphite flakes. Graphene ndi kakang'ono kakang'ono kagawo kakang'ono. Akuti millimeter imodzi ya flake graphite ili ndi zigawo pafupifupi 3 miliyoni za graphene, ndipo kukongola kwa graphene kumawonekera. Kuti tigwiritse ntchito chitsanzo chooneka, mawu amene timalemba papepala ndi mapensulo amakhala ndi zigawo zingapo kapena masauzande a zigawo za graphite. ine.
Njira yokonzekera graphene kuchokera ku flake graphite ndi yosavuta, yokhala ndi zolakwika zochepa ndi mpweya wa okosijeni, zokolola zambiri za graphene, kukula kwapakati, ndi zotsika mtengo, ndipo ndizoyenera kupanga mafakitale akuluakulu.
