Okwu mmalite nke Graphene
Graphene bụ akụkụ abụọ (2D) ụdị carbon ahaziri n'otu oyi akwa nke atọm na lattice hexagonal ugboro ugboro. E bu ụzọ kewapụ ya n'ime 2004 site Andre Geim na Konstantin Novoselov na Mahadum Manchester, ndị e nyere ihe nrite Nobel na Physics na 2010 maka nnwale ndị na-agbawa obi ha. Graphene bụ n'ezie atomiki-ọkọlọtọ ntupu mmanụ aṅụ nke atom carbon, nke na-eme ka ọ bụrụ onye otu ezinụlọ zuru oke, nke gụnyekwara graphite, unyi, carbon nanotubes, na fullerenes (bọọlụ).
Atụmatụ nke Graphene
Ike: Graphene bụ otu n'ime ihe ndị siri ike mara, na ike tensile nke gburugburu 130 gigapascals (GPA), nke siri ike karịa diamond ma sie ike karịa ígwè.
Mgbanwe: N'agbanyeghị ike ya, graphene na-agbanwekwa ma nwee ike gbagọrọ agbagọ ma ọ bụ tụgharịa na-enweghị agbaji.
Omume omume: Ọ bụ ezigbo onye nduzi ọkụ eletrik, na ngagharị eletrọn gafere 200 ugboro karịrị nke silicon.
Nrụpụta okpomọkụ: Graphene nwere conductivity thermal nke ukwuu, nke pụtara na ọ nwere ike iduzi okpomọkụ nke ọma.
nghọta: Graphene fọrọ nke nta ka ọ pụta ìhè, absorbing naanị banyere 2.3% nke ìhè, nke na-eme ka ọ dị mma maka ojiji na ngwá electronic transperent.
Kemịkalụ kwụsie ike: Ọ kwụsiri ike na kemịkalụ ma nwee ike iguzogide oxidation na ikuku, nke na-abawanye ogologo oge ya.
Mpaghara dị elu: Otu gram nke graphene nwere oke elu ruo 2630 square mita, nke bara uru maka ngwa na-achọ nnukwu ebe elu.
Ngwa nke Graphene
Eletrọnịkị: Graphene nwere ike gbanwee ngwa eletrọnịkị n'ihi nnukwu ngagharị elektrọn na nghọta ya, na-eme ka ọ dị mma maka ihuenyo mmetụ, sel fotovoltaic, na ngwa eletrọnịkị dị elu.
Nchekwa ike: Ọ nwere ike melite arụmọrụ nke batrị na supercapacitors n'ihi elu elu ya na conductivity.
Ngwakọta agwakọta: Site n'ịgbakwunye graphene na rọba, ọla, ma ọ bụ ceramik, ihe ndị mejupụtara nwere ike nweta nkwalite n'ibu, thermal, na eletriki Njirimara.
Injinia biomedical: Nkwekọrịta nke Graphene na ikike iburu ọgwụ na-eme ka ọ baa uru maka usoro nnyefe ọgwụ na injinịa anụ ahụ.
Mmiri dị ọcha: Membrane nke dabere na ya nwere ike ihichapụ adịghị ọcha na mmiri, gụnyere nnu, nje bacteria, na nje.
Ihe mmetụta: Ihe mmetụta graphene nwere ike ịchọpụta oke gas ma ọ bụ biomolecules nkeji nkeji, na-eme ka ha baa uru na nlekota gburugburu ebe obibi na nchọpụta ahụike.
Eletrọnịkị na-agbanwe agbanwe: Ngbanwe ya na ihe omume na-eme ka ọ dị mma maka ngwaọrụ ndị na-eyi uwe na ihe ngosi na-agbanwe agbanwe.

Ajụjụ gbasara Graphene
Kedu ka esi emepụta graphene?
Enwere ike ịmepụta graphene n'ọtụtụ ụzọ, gụnyere n'ibu exfoliation (peeling n'ígwé na graphite), kemịkalụ vapor ntinye (CVD), na mbelata kemịkalụ nke graphene oxide.
Ọ bụ graphene na-egbu egbu?
Nnyocha ndị e mere ugbu a na-egosi na graphene nwere ike inwe ụfọdụ nsogbu nsị, karịsịa ma ọ bụrụ na ikuru ume, mana nyocha ọzọ dị mkpa iji ghọta nke ọma mmetụta ahụike ya nwere ike ime.
Enwere ike imepụta graphene n'ụba?
Ee, ụzọ dị ka CVD na-enye ohere maka mmepụta nke graphene n'ọtụtụ buru ibu, n'agbanyeghị na ị nweta otu ịdị mma na nnukwu mpempe akwụkwọ na-anọgide na-esiri ike.
