Graphene ndi kristalo wa mbali ziwiri wopangidwa ndi maatomu a kaboni atomu imodzi yokha yokhuthala, yochotsedwa ku zinthu za flake graphite. Graphene ali ndi ntchito zosiyanasiyana chifukwa cha zinthu zake zabwino kwambiri mu optics, magetsi ndi zimango. Ndiye pali ubale pakati pa flake graphite ndi graphene? Zotsatirazi zing'onozing'ono za Kusanthula ubale pakati pa flake graphite ndi graphene:
Chojambula cha graphite
1. Njira yotulutsira misala ya graphene sikuti imapezeka makamaka kuchokera ku flake graphite, koma kuchokera ku mpweya wokhala ndi mpweya monga methane ndi acetylene. Ngakhale dzinali, kupanga ma graphene sikuchokera ku flake graphite. Amapangidwa kuchokera ku mpweya wokhala ndi mpweya monga methane ndi acetylene, ndipo ngakhale pano pali njira zochotsera graphene ku zomera zomwe zimamera, ndipo tsopano pali njira zochotsera graphene kumitengo ya tiyi.
2. Flake graphite ili ndi mamiliyoni a graphene. Graphene kwenikweni alipo mu chilengedwe, ngati ubale graphene ndi flake graphite, ndiye graphene wosanjikiza ndi wosanjikiza ndi flake graphite, graphene ndi yaing'ono kwambiri monolayer dongosolo. Millimeter imodzi ya flake graphite akuti ili ndi zigawo pafupifupi mamiliyoni atatu za graphene, ndipo kukongola kwa graphene kungawonekere, kugwiritsa ntchito chitsanzo chojambula, tikamalemba mawu papepala ndi pensulo, pali zigawo zingapo kapena masauzande ambiri. ku graphene.
Njira yokonzekera graphene kuchokera ku flake graphite ndi yosavuta, yokhala ndi zolakwika zochepa komanso mpweya wa okosijeni, zokolola zambiri za graphene, kukula kwake, ndi mtengo wotsika mtengo, womwe ndi woyenera kupanga mafakitale akuluakulu.
