Graphene bụ kristal nwere akụkụ abụọ nwere atom carbon naanị otu atom gbara ọkpụrụkpụ, nke ewepụrụ na ihe graphite flake. Graphene nwere ngwa dịgasị iche iche n'ihi njirimara ya dị mma na ngwa anya, ọkụ eletrik na igwe. Yabụ enwere mmekọrịta dị n'etiti graphite flake na graphene? Nke a obere usoro nyocha nke mmekọrịta dị n'etiti flake graphite na graphene:
Akara graphite
1. The mmịpụta usoro maka uka mmepụta nke graphene bụghị tumadi nwetara site flake graphite, ma si carbon-nwere gas dị ka methane na acetylene. N'agbanyeghị aha ahụ, mmepụta graphene anaghị esite na graphite flake. A na-eme ya site na gas ndị nwere carbon dị ka methane na acetylene, na ọbụna ugbu a, e nwere ụzọ isi wepụ graphene na osisi na-eto eto, ma ugbu a, e nwere ụzọ isi wepụ graphene na osisi tii.
2. Flake graphite nwere nde graphene. Graphene n'ezie dị na ọdịdị, ma ọ bụrụ na mmekọrịta dị n'etiti graphene na flake graphite, graphene oyi akwa site oyi akwa bụ flake graphite, graphene bụ a nnọọ obere monolayer Ọdịdị. A na-ekwu na otu millimita flake graphite nwere ihe dị ka nde atọ nke graphene, na ịdị mma nke graphene nwere ike ịhụ, iji ihe atụ eserese, mgbe anyị na-eji pensụl dee okwu na mpempe akwụkwọ, e nwere ọtụtụ ma ọ bụ iri puku kwuru iri puku n'ígwé. nke graphene.
Usoro nkwadebe nke graphene sitere na graphite flake dị mfe, na-enwe obere ntụpọ na ọdịnaya oxygen, mkpụrụ dị elu nke graphene, oke nha, na ọnụ ala dị ala, nke kwesịrị ekwesị maka mmepụta ụlọ ọrụ buru ibu.
