Izizathu zezimpawu ezisezingeni eliphakeme ze-flake graphite

I-flake graphite isetshenziswa kabanzi embonini, enezici zayo ezisezingeni eliphakeme. Namuhla, i-xioobian ye-furuite ye-xiaobian izokutshela izizathu zezimpawu ezisezingeni eliphakeme ze-flake graphite kusuka ezicini zezakhi zomndeni kanye namakristalu ahlanganisiwe:

Okokuqala, izici ezisezingeni eliphakeme zezakhi zekhabhoni ezakhai-flake graphite.

1. Izakhiwo zamakhemikhali zekhabhoni yaleli ndalo zizinzile ngokushisa ekamelweni, futhi ziyinto engabonakali emanzini, zihlasele i-acid, i-alkali ye-alkali ne-organic solvents;

2, ukuphendula nge-oxygen emazingeni okushisa aphezulu aphezulu ukukhiqiza ikhabhoni i-dioxide noma i-carbon monoxide; E-halogen, i-fluorine kuphela engasabela ngqo ngekhabhoni yale esele;

3. Ngaphansi kokushisa, i-carbon elemental ifakwa kalula nge-acid;

I-4. Ekushiseni okuphezulu, i-carbon nayo ingasabela ngezinsimbi eziningi ukukhiqiza i-carbides yensimbi;

5. Ikhabhoniiyancishiswa futhi ingasetshenziselwa ukushaya izinsimbi zokushisa okuphezulu.

Okwesibili, izici zamakristalu ahlanganisiwe akhiwa nge-flake graphite.

1. Ku-graphite crystal, ama-athomu e-carbon ku-hybridize efanayo i-hybridize ne-SP2 ukwakha ama-combared bond, futhi i-athomu ngalinye le-carbon lixhumene namanye ama-athomu amathathu ngama-athomu amathathu ama-combared. Ama-athomu ayisithupha wekhabhoni akha indandatho ye-hexagonal endizeni efanayo, welula esakhiweni esinqunyelwe, lapho ubude be-CC isibopho se-CC buyikho konke 142pm, okungububanzi be-atomic crystal, ngakho-ke i-atomic crystal.

2. Izendlalelo zamakristalu e-graphite zihlukaniswe ngo-340pm, okuyibanga elikhulu, futhi zihlanganiswa ne-van der Waals Force, okungukuthi, izingqimba zingezakho amakristalu ama-molecula. Kodwa-ke, ngenxa yesibopho esiqinile phakathi kwama-athomu e-carbon ku-under efanayo yendiza, kunzima kakhulu ukubhubhisa, ngakho-ke iphuzu lokuncibilikai-graphiteFuthi kuphezulu futhi izakhiwo zamakhemikhali zizinzile.
