Graphene yog exfoliated los ntawm flake graphite cov khoom, ib tug ob-dimensional siv lead ua muaj li ntawm carbon atoms uas tsuas yog ib tug atomic tuab. Vim nws zoo heev optical, hluav taws xob thiab txhua yam khoom, graphene muaj ntau yam kev siv. Puas yog flake graphite thiab graphene muaj feem cuam tshuam? Cov nram qab no Furuite graphite editor soj ntsuam kev sib raug zoo ntawmflake graphitethiab graphene:
1. Txoj kev rho tawm ntawm graphene pawg ntau lawm tsis yog los ntawm flake graphite, tab sis los ntawm cov pa roj carbon monoxide xws li methane thiab acetylene. Txawm hais tias lub npe muaj lo lus graphite, kev tsim cov graphene tsis yog muab los ntawm flake graphite. Hloov chaw, nws tau txais los ntawm cov pa roj carbon monoxide xws li methane thiab acetylene. Txawm tias txoj kev tshawb fawb tam sim no tau muab rho tawm los ntawm cov ntoo cog ntoo, thiab tam sim no muaj ib txoj hauv kev ntawm kev rho tawm graphene los ntawm cov ntoo tshuaj yej.
2. Graphite flakes muaj ntau lab ntawm graphene. Graphene yeej muaj nyob rau hauv qhov. Yog tias muaj kev sib raug zoo ntawm graphene thiab flake graphite, ces graphene yog superimposed txheej los ntawm txheej los tsim graphite flakes. Graphene yog ib txheej txheej me me heev. Nws tau hais tias ib millimeter ntawm flake graphite muaj txog 3 lab txheej ntawm graphene, thiab qhov zoo ntawm graphene tuaj yeem pom. Txhawm rau siv qhov ua piv txwv pom, cov lus peb sau rau ntawm daim ntawv nrog xaum muaj ob peb lossis kaum tawm txhiab txheej ntawm graphite. ib ene.
Txoj kev npaj graphene los ntawm flake graphite yog yooj yim, nrog rau ob peb yam tsis xws luag thiab cov pa oxygen, siab graphene yield, nruab nrab loj, thiab tus nqi qis, thiab yog haum rau loj-scale industrial ntau lawm.
