I-graphene ikhishwe ku-flake graphite material, icrystal enezinhlangothi ezimbili ehlanganiswe ama-athomu ekhabhoni enogqinsi olulodwa lwe-athomu. Ngenxa yezakhiwo zayo ezinhle kakhulu ze-optical, zikagesi nezemishini, i-graphene inezinhlobonhlobo zezinhlelo zokusebenza. Ngakho ingabe i-flake graphite ne-graphene ihlobene? Umhleli olandelayo we-Furuite graphite uhlaziya ubudlelwano phakathii-flake graphitekanye ne-graphene:
1. Indlela yokukhipha ukukhiqizwa kwe-graphene mass ayitholakali ikakhulukazi ku-flake graphite, kodwa kumagesi aqukethe i-carbon njenge-methane ne-acetylene. Nakuba leli gama linegama elithi graphite, ukukhiqizwa kwe-graphene akuveli ikakhulukazi ku-flake graphite. Kunalokho, itholakala kumagesi ane-carbon anjenge-methane ne-acetylene. Ngisho nendlela yamanje yocwaningo ikhishwa esihlahleni sesitshalo esikhulayo, futhi manje kunendlela yokukhipha i-graphene ezihlahleni zetiye.
2. Ama-graphite flakes aqukethe izigidi ze-graphene. I-graphene empeleni ikhona emvelweni. Uma kukhona ubudlelwano phakathi kwe-graphene ne-flake graphite, khona-ke i-graphene iba ungqimba olungaphezulu ngongqimba ukuze yakhe ama-graphite flakes. I-graphene iyisakhiwo esincane kakhulu esinesendlalelo esisodwa. Kuthiwa imilimitha eyodwa ye-flake graphite iqukethe izendlalelo ezingaba yizigidi ezi-3 ze-graphene, futhi ukucoleka kwe-graphene kungabonakala. Ukusebenzisa isibonelo esibonakalayo, amagama esiwabhala ephepheni ngamapensela aqukethe izingqimba ezimbalwa noma amashumi ezinkulungwane zegraphite. ene.
Indlela yokulungisa i-graphene kusuka ku-flake graphite ilula, inokukhubazeka okumbalwa nokuqukethwe kwe-oxygen, isivuno esiphezulu se-graphene, usayizi olinganiselwe, nezindleko eziphansi, futhi ifaneleka ukukhiqizwa kwezimboni ezinkulu.
