Ubudlelwano phakathi kwe-flake graphite ne-graphene

I-graphene iyikristalu enezinhlangothi ezimbili eyenziwe ngama-athomu ekhabhoni kuphela ugqinsi lwe-athomu eyodwa, ekhishwe ku-flake graphite material. I-graphene inezinhlobonhlobo zezinhlelo zokusebenza ngenxa yezakhiwo zayo ezinhle kakhulu ku-optics, ugesi kanye nemishini. Ngakho ingabe kukhona ubudlelwano phakathi kwe-flake graphite ne-graphene? Uchungechunge oluncane olulandelayo Lokuhlaziywa kobudlelwane phakathi kwe-flake graphite ne-graphene:

Faka i-graphite

1. Indlela yokukhipha yokukhiqiza i-graphene ngobuningi ayitholakali ikakhulukazi ku-flake graphite, kodwa kumagesi ane-carbon anjenge-methane ne-acetylene. Ngaphandle kwegama, ukukhiqizwa kwe-graphene akuveli ngokuyinhloko ku-flake graphite. Yenziwe ngamagesi ane-carbon anjenge-methane ne-acetylene, futhi ngisho namanje zikhona izindlela zokukhipha i-graphene ezitshalweni ezikhulayo, futhi manje sekunezindlela zokukhipha i-graphene ezihlahleni zetiye.

2. I-Flake graphite iqukethe izigidi ze-graphene. I-graphene empeleni ikhona endalweni, uma ubudlelwano phakathi kwegraphene ne-flake graphite, khona-ke ungqimba lwe-graphene ngongqimba luyi-flake graphite, i-graphene iyisakhiwo esincane kakhulu se-monolayer. Imilimitha eyodwa ye-flake graphite kuthiwa inezingqimba ezingaba yizigidi ezintathu zegraphene, futhi ukucoleka kwegraphene kungabonakala, ngokusebenzisa isibonelo esicacile, lapho sibhala amagama ephepheni ngepensela, kunezingqimba eziningana noma amashumi ezinkulungwane. kwe-graphene.

Indlela yokulungiselela i-graphene evela ku-flake graphite ilula, eneziphambeko ezincane kanye nokuqukethwe kwe-oxygen, isivuno esikhulu se-graphene, usayizi olinganiselwe, nezindleko eziphansi, ezifanele ukukhiqizwa kwezimboni ezinkulu.
