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. Kwikristale yegrafiti, iiathom zekhabhoni ezikwileya efanayo ziyadityaniswa nge-sp2 ukuze zenze iibhondi ze-covalent, kwaye iathom nganye yekhabhoni iqhagamshelwe nezinye iiathom ezintathu ngeebhondi ezintathu ze-covalent. Iiathom ezintandathu zekhabhoni zenza indandatho yehexagonal kwindawo enye, yolulela kwisakhiwo esineeleya, apho ubude bebhondi ye-CC bond buyi-142pm, eyinxalenye yobude bebhondi yekristale ye-atomic, ngoko ke kwileya efanayo, yikristale ye-atomic.
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.
