Graphene inobviswa kubva mu flake graphite material, crystal ine mativi maviri inoumbwa nemaatomu ekabhoni ane ukobvu hweatomu imwe chete. Nekuda kwehunhu hwayo hwakanaka hwe optical, electrical uye mechanical, graphene ine mashandisirwo akasiyana-siyana. Saka flake graphite ne graphene zvine hukama here? Mupepeti we Furuite graphite anotevera anoongorora hukama huripo pakatigirafiti yegandauye graphene:
1. Nzira yekubvisa graphene yakawanda haiwanikwe zvakanyanya kubva ku flake graphite, asi kubva kumagasi ane kabhoni akadai se methane ne acetylene. Kunyangwe zita racho riine izwi rekuti graphite, kugadzirwa kwe graphene hakubvi zvakanyanya kubva ku flake graphite. Pane kudaro, inowanikwa kubva kumagasi ane kabhoni akadai se methane ne acetylene. Kunyangwe nzira yekutsvagisa iripo ikozvino inotorwa kubva pamuti wemiti uri kukura, uye ikozvino kune nzira yekubvisa graphene kubva mumiti yetii.
2. Mafuremu eGraphite ane mamiriyoni egraphene. Graphene iripo zvechokwadi muzvisikwa. Kana paine hukama pakati pegraphene neflake graphite, saka graphene inoiswa pamusoro pefuremu nefuremu kuti igadzire mafuremu egraphite. Graphene chimiro chidiki kwazvo chine furemu imwe chete. Zvinonzi millimeter imwe yeflake graphite ine mafuremu egraphite angangoita mamiriyoni matatu, uye hutete hwegraphene hunogona kuonekwa. Semuenzaniso wekuona, mazwi atinonyora papepa nemapenzura ane mafuremu akawanda kana makumi ezviuru egraphite. ene.
Nzira yekugadzira graphene kubva ku flake graphite iri nyore, ine zvikanganiso zvishoma uye oxygen yakawanda, goho re graphene rakawanda, saizi iri pakati nepakati, uye mutengo wakaderera, uye yakakodzera kugadzirwa kwemaindasitiri makuru.
