Qhov sib txawv tseem ceeb ntawm graphene thiab fullerene yog tias graphene muaj ob sab qauv, thaum fullerene muaj peb sab qauv.

Fundamally, graphene thiab fullerene yog allotropes ntawm carbon. Qhov ntawd yog; muaj plaub loj allotropes ntawm carbon; graphene, fullerene, thiab lwm yam ob yog pob zeb diamond thiab graphite.

Graphene yog dab tsi?

Graphene yog ib qho allotrope ntawm cov pa roj carbon uas tshwm sim ua ob sab, uas tuaj yeem hu ua "ob-seem hexagonal lattice". Ntxiv mus, nws yog infinitely loj aromatic molecule. Tus qauv yog raws li nram no:

Daim duab 01: Cov qauv ntawm daim ntawv Graphene

Tsis tas li ntawd, cov khoom no muaj cov khoom tshwj xeeb:

  • Piv rau nws cov tuab, graphene muaj zog dua li cov hlau uas muaj zog tshaj plaws.
  • Nws ua kom muaj cua sov thiab hluav taws xob zoo
  • Thiab, kub hnyiab ntawm qhov kub qis heev
  • Nws yuav luag pob tshab
  • Kuj, nws yog qhov loj thiab muaj cov kab mob tsis sib xws
  • Ntxiv mus, nws muaj quantum oscillations
  • Carbon atoms ntawm cov npoo ntawm nws daim ntawv muaj cov tshuaj reactivity tshwj xeeb
  • Ntxiv mus, qhov tsis xws luag hauv daim ntawv txhim kho cov tshuaj reactivity
  • Dhau li ntawm, cov nplooj ntawv graphene pawg los ua graphite

YFullerene yog dab tsi?

Fullerene yog ib qho allotrope ntawm carbon uas tshwm sim raws li spheres ntawm carbon. Yog li ntawd, tsis zoo li graphene, fullerene yog 3D qauv. Tsis tas li ntawd, nws tshwm sim raws li ib tug loj spheroidal molecule, thiab nws muaj ib lub tawb tsim los ntawm rau caum los yog ntau tshaj atoms.

Daim duab 02: Tus qauv ntawm Fullerene

Nws yog cov qauv kaw, yog li tsis muaj npoo. Ntxiv mus, nws muaj ib qho thiab ob daim ntawv cog lus ntawm carbon atoms. Ntxiv mus, lub tawb ntawm fullerene yog tsim los ntawm rings ntawm carbon atoms (yuav muaj 5 mus rau 7 carbon atoms ib lub nplhaib). Txawm hais tias nws feem ntau tshwm sim raws li tus kheej kheej, nws kuj tuaj yeem tshwm sim raws li ellipsoid, raj lossis lwm yam duab. Ntxiv mus, qhov loj ntawm lub fullerene molecule yuav txawv.

Qhov txawv ntawm Graphene thiab Fullerene yog dab tsi?

Graphene yog ib qho allotrope ntawm carbon uas tshwm sim raws li cov nplooj ntawv ntawm cov pa roj carbon thaum fullerene yog ib qho allotrope ntawm carbon uas tshwm sim raws li spheres ntawm carbon. Qhov sib txawv tseem ceeb ntawm graphene thiab fullerene yog tias graphene muaj ob-seem qauv, thaum fullerene muaj peb-dimensional qauv. Ntxiv mus, tsis muaj cov npoo hauv fullerene, tab sis hauv grapheme, muaj cov npoo.

Summary – Graphene vs Fullerene

Hauv luv luv, graphene thiab fullerene yog ib qho tseem ceeb allotropic qauv ntawm carbon. Qhov sib txawv tseem ceeb ntawm graphene thiab fullerene yog tias graphene muaj ob-seem qauv, thaum fullerene muaj peb-dimensional qauv.
