Ubudlelwano phakathi kwe-flake graphite ne-graphene

I-Graphene iyi-crystal enezici ezimbili ezenziwe ngama-athomu e-carbon kuphela ama-athomu athile, ahluthwe entweni ye-flake graphite. I-Graphene inezinhlobonhlobo zezicelo ngenxa yezakhiwo zayo ezinhle kakhulu ku-Optics, ugesi kanye nama-mechanics. Ngakho-ke kukhona ubudlelwano phakathi kwe-flake graphite ne-graphiene? Uchungechunge oluncane olulandelayo lokuhlaziywa kobudlelwano phakathi kwe-flake graphite ne-graphene:

I-flake graphite

1. Indlela yokukhishwa kokukhiqizwa ngobuningi kwe-graphiene ayitholakalanga ngokutholwa i-flake graphite, kodwa kusuka kumagesi e-carbon-aqukethe amagesi aqukethe i-methane ne-acetylene. Ngaphandle kwegama, ukukhiqizwa kwe-graphene akuqhamuki ngokuyinhloko i-flake graphite. Kwenziwe kusuka kumagesi aqukethe ama-carbon aqukethe i-methane ne-acetylene, futhi manje kunezindlela zokukhipha i-graphene kusuka ezitshalweni ezikhulayo, futhi manje kunezindlela zokukhipha i-graphene yezihlahla zetiye.

2. I-Flake Plasste iqukethe izigidi ze-graphene. I-Graphene empeleni ikhona emvelweni, uma ubudlelwane phakathi kwe-graphene kanye ne-flake, bese i-graphene ungqimba nge-flake graphite, i-graphene yisakhiwo esincane kakhulu se-monolayer. Amamilimitha owodwa we-flake graphite kuthiwa aqukethe izingqimba ezingaba yizigidi ezintathu ze-grapheene, kanye nobunzima be-graphic bungabonakala, ukusebenzisa isibonelo esibonakalayo, lapho sibhala amagama ephepheni, kunamakhulu amaningana noma izinkulungwane zezendlalelo zezendlalelo zezinceku ze-graphil.

Indlela yokulungiselela ye-graphite ye-flake ilula, ngokuqukethwe okuncane nokuqukethwe komoya-mpilo, isivuno esikhulu se-graphene, usayizi olinganiselayo, kanye nezindleko eziphansi, ezilungele ukukhiqizwa okukhulu kwezimboni.
