Graphene yog ob-seem crystal ua los ntawm carbon atoms tsuas yog ib atom tuab, stripped los ntawm ib tug kab txhuam hniav graphite. Graphene muaj ntau cov ntawv thov vim nws cov khoom zoo hauv Optics, hluav taws xob thiab kev siv tshuab. Yog li puas muaj kev sib raug zoo ntawm Fleake Graphite thiab Graphene? Cov hauv qab no cov kev soj ntsuam me me ntawm kev sib raug zoo ntawm Clear Graphite thiab Graphene:
Fig Kas graphite
1. Cov txheej txheem rho tawm rau huab hwm coj muaj cov graphene tsis yog muab los ntawm Flake Graphite, tab sis los ntawm cov pa roj carbon-muaj me me xws li methane thiab acetylene. Txawm hais tias lub npe, graphene ntau lawm tsis yog los ntawm flake graphite. Nws tau ua los ntawm cov pa roj carbon-muaj cov roj av me me, thiab tam sim no muaj txoj hauv kev los rho tawm graphene los ntawm cov dej tshuaj yej ntoo.
2. Flara graphite muaj ntau lab ntawm graphene. Graphene yeej muaj nyob rau hauv qhov, yog tias kev sib txheeb ntawm graphene thiab flake graphite, ces graphene txheej los ntawm txheej graphite, graphene yog ib tus qauv monolayer me heev. Ib tug millimeter ntawm flake graphite tau hais kom muaj txog peb lab txheej ntawm graphene, thaum peb sau cov ntawv sau rau, muaj ntau lossis kaum ob txheej ntawm graphene.
Txoj kev npaj npaj ntawm flake graphite yog yooj yim, nrog tsawg tsis xws luag thiab cov txiaj ntsig ntau, uas haum rau cov khoom lag luam loj.
