Izizathu zeempawu ezikumgangatho ophezulu we-flake graphite

I-Flake graphite isetyenziswa kakhulu kwishishini, elivela kwiimpawu zayo ezikumgangatho ophezulu. Namhlanje, iFuruite Graphite Xiaobian iya kukuxelela izizathu zeempawu ezikumgangatho ophezulu we-flake graphite ukusuka kwimiba yokwakheka kosapho kunye neekristale ezixubeneyo:

Okokuqala, iimpawu eziphakamileyo zekhabhoni ezakhayoigrafu yeflake.

1. Iimpawu zeekhemikhali ze-elemental carbon zizinzile kwiqondo lokushisa, kwaye ayinyibiliki emanzini, i-asidi ye-dilute, i-alkali edibeneyo kunye ne-organic solvents;

2, ukuphendula ngeoksijini kumaqondo obushushu ahlukeneyo ukuvelisa icarbon dioxide okanye icarbon monoxide; Kwi-halogen, kuphela i-fluorine inokusabela ngokuthe ngqo nge-carbon elemental;

3. Ngaphantsi kokufudumeza, i-carbon elemental i-oxidized ngokulula nge-asidi;

4. Kwiqondo lokushisa eliphezulu, ikhabhoni inokusabela kunye neentsimbi ezininzi ukuvelisa i-carbides yensimbi;

5. Ikhabhoniiyancitshiswa kwaye ingasetyenziselwa ukunyibilikisa isinyithi kubushushu obuphezulu.

Okwesibini, iimpawu zeekristale ezixubileyo ezenziwe nge-flake graphite.

1. Kwikristale yegraphite, iiathom zekhabhoni kumaleko afanayo zixuba kunye ne-sp2 ukwenza iibhondi ezidibeneyo, kwaye i-athomu yekhabhoni nganye idityaniswe nezinye iiathom ezintathu ngamabhondi amathathu adibeneyo. Iiathom zekhabhoni ezintandathu zenza isangqa esinehexagonal kwinqwelomoya enye, yolulela kwisakhiwo esimaleko, apho ubude bobhondi be-CC bond yonke i-142pm, eyoluhlu lobude bekristale yeathom, ke kuluhlu olufanayo, luyi-athomu. ikristale.

2. Iingqimba zeekristali zegraphite zihlulwe ngu-340pm, umgama omkhulu, kwaye zidibaniswe yi-van der Waals force, oko kukuthi, iileyile ze-crystals ze-molecular. Nangona kunjalo, ngenxa yebhondi elomeleleyo phakathi kweeathom zekhabhoni kwinqanaba elifanayo lenqwelomoya, kunzima kakhulu ukutshabalalisa, ngoko ke indawo yokunyibilika.igraphitenayo iphezulu kwaye iimpawu zayo zemichiza zizinzile.
