I-Flake graphite isetyenziswa kakhulu kushishino, nto leyo ebangelwa ziimpawu zayo ezisemgangathweni ophezulu. Namhlanje, i-Furuite Graphite Xiaobian iza kukuxelela izizathu zeempawu ezikumgangatho ophezulu ze-flake graphite kwizinto ezidityanisiweyo zentsapho kunye neekristale ezixutyiweyo:
Okokuqala, iimpawu ezisemgangathweni ophezulu zezinto zekhabhoni ezenzaigrafayithi eqingqiweyo.
1. Iipropati zeekhemikhali zekhabhoni ye-elemental zizinzile xa kushushu kwigumbi, kwaye azinyibiliki emanzini, zinyibilikisa i-asidi, zinyibilikisa i-alkali kunye nezinyibilikisi ze-organic;
2, isabela neoksijini kumaqondo obushushu aphezulu ahlukeneyo ukuze ivelise i-carbon dioxide okanye i-carbon monoxide; Kwi-halogen, yi-fluorine kuphela enokusabela ngokuthe ngqo ne-elemental carbon;
3. Xa ifudunyezwa, ikhabhoni ye-elemental inyibilikiswa lula yi-asidi;
4. Xa kushushu kakhulu, ikhabhoni isenokusabela kwiintsimbi ezininzi ukuvelisa iikhabhoyidi zesinyithi;
5. Ikhabhoniiyancitshiswa kwaye ingasetyenziselwa ukunyibilikisa iintsimbi kubushushu obuphezulu.
Okwesibini, iimpawu zeekristale ezixutyiweyo ezenziwe ngegrafiti yeflake.
1. Kwi-graphite crystal, ii-athomu zekhabhoni ezikwi-layer enye ziyaxutywa nge-sp2 ukuze zenze ii-covalent bonds, kwaye i-athomu nganye yekhabhoni iqhagamshelwe nezinye ii-athomu ezintathu ngee-covalent bonds ezintathu. Ii-athomu zekhabhoni ezintandathu zenza i-hexagonal ring kwi-plane enye, zisolulela kwisakhiwo esinee-layer, apho ubude be-bond ye-CC bond buyi-142pm yonke, eyinxalenye yobude be-bond ye-atomic crystal, ngoko ke kwi-layer enye, yi-atomic crystal.
2. Iileya zeekristale zegrafiti zahlulwe nge-340pm, nto leyo ekude kakhulu, kwaye zidityaniswe ngamandla e-van der Waals, oko kukuthi, iileya zezekristale zemolekyuli. Nangona kunjalo, ngenxa yobudlelwane obuqinileyo phakathi kweeathom zekhabhoni kwileya enye yeplane, kunzima kakhulu ukuyitshabalalisa, ngoko ke inqanaba lokunyibilika kweigrafayithiikwaphezulu kwaye iipropati zayo zeekhemikhali zizinzile.
