Thermal Conductivity Txoj Cai: Anisotropic Layered Structure
Graphite yog tsim los ntawm sp² hybridized carbon atoms teem rau hauv hexagonal txheej txheej:
Nyob rau hauv txheej (hauv lub dav hlau): Muaj zog covalent bonds, phonon kis tau tus mob efficiency siab heev → Ultra-siab thermal conductivity nyob rau hauv lub dav hlau
Nruab nrab ntawm cov khaubncaws sab nraud povtseg (perpendicular mus rau lub dav hlau): Tsis muaj zog van der Waals rog → Tsis tshua muaj cua sov conduction sab nraum lub dav hlau (≈ 10–25 W / m・K)
Cov yam ntxwv tseem ceeb: Anisotropy - Cov cua sov ua kom muaj zog heev raws lub dav hlau, tsis muaj zog hluav taws xob ua hluav taws xob perpendicular rau lub dav hlau; Tsim yuav tsum tau teem caij nyob rau hauv lub dav hlau thaum tsim, rau lateral tshav kub expansion.

Kev txwv (tsim yuav tsum-paub)
Anisotropy, ntsug hluav taws xob sib txawv: Tsis tuaj yeem ua cov cua sov ntsug ib leeg; nws yuav tsum tau ua ke nrog tooj liab / VC / fins;
Brittleness, tsis tshua muaj neeg kho tshuab lub zog: Graphite los xij yog nquag tawg; lawv xav tau rov qab kua nplaum / txheej / sib xyaw substrate;
Conductive, yuav tsum tau kho rwb thaiv tsev: Kom tsis txhob luv luv Circuit Court;
Yooj yim oxidized nyob rau hauv siab - cua kub: > 450℃yuav tsum tau SiC/BN/TaC txheej tiv thaiv.
