A na-ekpochapụ graphene site na flake graphite ihe onwunwe, kristal nwere akụkụ abụọ nke atom carbon nke bụ naanị otu nnukwu atọm. N'ihi ọmarịcha ngwa anya, eletriki na akụrụngwa ya, graphene nwere ọtụtụ ngwa. Ya mere flake graphite na graphene nwere njikọ? Onye nchịkọta akụkọ graphite Furuite na-enyocha mmekọrịta dị n'etitigraphite flakena graphene:
1. The mmịpụta usoro nke graphene uka mmepụta bụghị tumadi nwetara site flake graphite, ma si carbon-nwere gas dị ka methane na acetylene. Ọ bụ ezie na aha ahụ nwere okwu graphite, mmepụta nke graphene abụghị nke sitere na graphite flake. Kama nke ahụ, a na-enweta ya site na gas ndị nwere carbon dị ka methane na acetylene. Ọbụna usoro nyocha nke ugbu a na-esi na osisi osisi na-eto eto, ma ugbu a, e nwere ụzọ isi wepụ graphene na osisi tii.
2. Ihe osise eserese nwere nde graphene. Graphene dị n'ezie na okike. Ọ bụrụ na enwere mmekọrịta n'etiti graphene na flake graphite, mgbe ahụ, a na-etinye graphene oyi akwa site na oyi akwa iji mepụta flakes graphite. Graphene bụ obere ihe owuwu nwere otu oyi akwa. A na-ekwu na otu millimita nke graphite flake nwere ihe dị ka nde 3 nke graphene, a pụkwara ịhụ ịdị mma nke graphene. Iji mee ihe atụ a na-ahụ anya, okwu ndị anyị na-ede na pensụl nwere ọtụtụ ma ọ bụ iri puku kwuru iri puku graphite. ebe.
Usoro maka ịkwadebe graphene sitere na graphite flake dị mfe, na-enwe ntụpọ ole na ole na ọdịnaya oxygen, mkpụrụ osisi graphene dị elu, nha dị oke ọnụ, na ọnụ ala dị ala, ọ dịkwa mma maka mmepụta ụlọ ọrụ buru ibu.
