Graphene icrystal-dimensional crystal yakagadzirwa nekabhoni atomu chete gobvu atomu, yakabviswa kubva paflake graphite zvinhu. Graphene ine huwandu hwakasiyana hwekushandisa nekuda kwehunhu hwayo hwakanaka mune optics, magetsi uye makanika. Saka pane hukama pakati peflake graphite negraphene? Aya madiki anotevera akateedzana Ongororo yehukama pakati peflake graphite negraphene:
Flake graphite
1. Nzira yekuchera yekugadzirwa kwehuwandu hwegraphene haisi kunyanya kuwanikwa kubva kune flake graphite, asi kubva kune carbon-containing magasi akadai semethane uye acetylene. Pasinei nezita racho, kugadzirwa kwegraphene hakubvi kune flake graphite. Yakagadzirwa kubva kumagasi ane kabhoni semethane neacetylene, uye kunyangwe ikozvino kune nzira dzekubvisa graphene kubva muzvirimwa zvinokura, uye ikozvino kune nzira dzekubvisa graphene kubva mumiti yetii.
2. Flake graphite ine mamiriyoni egraphene. Graphene iriko chaizvo mumasikirwo, kana hukama pakati pegraphene neflake graphite, ipapo graphene layer by layer is flake graphite, graphene idiki kwazvo monolayer chimiro. Millimita imwe yeflake graphite inonzi ine girafu dzinenge mamiriyoni matatu, uye kunaka kwegraphene kunogona kuonekwa, kushandisa muenzaniso wakajeka, patinonyora mashoko pabepa nepenzura, pane akati wandei kana makumi ezviuru zvezvikamu. ye graphene.
Nzira yekugadzirira ye graphene kubva kune flake graphite iri nyore, ine zvishoma zvikanganiso uye zvinyorwa zveokisijeni, goho rakakwirira re graphene, hukuru hwepakati, uye mari shoma, iyo inokodzera kugadzirwa kwemabhizimisi makuru.
