Pob zeb diamond nanoparticles hmoov tuaj yeem siv rau thermal conductive, tshav kub dissipation.

Pob zeb diamond muaj siab thermal conductivity, uas yog qhov siab tshaj plaws ntawm cov pob zeb hauv av paub.Pob zeb diamond yog ib qho tsis muaj xim octahedral siv lead ua, uas yog txuas los ntawm carbon atoms nrog plaub valence bonds.Nyob rau hauv pob zeb diamond siv lead ua, carbon atoms txuas rau ib leeg nyob rau hauv ib tug tetrahedral daim ntawv cog lus los tsim ib tug infinite peb-dimensional moj khaum.Nws yog ib qho atomic crystal.Txhua cov pa roj carbon atom tsim ib daim ntawv cog lus nrog rau lwm cov 4 carbon atoms ntawm sp3 hybrid orbital los tsim ib qho tetrahedron li niaj zaus.Vim muaj zog CC daim ntawv cog lus nyob rau hauv pob zeb diamond, tag nrho cov valence electrons koom nyob rau hauv tsim ntawm covalent bonds, thiab tsis muaj dawb electrons.Cov qauv lattice ruaj khov no ua rau carbon atoms muaj thermal conductivity zoo heev.

Pob zeb diamond yog cov khoom siv thermal conductivity siab tshaj plaws nyob rau hauv qhov xwm txheej.Lub thermal conductivity (Hom Ⅱ Pob zeb diamond) tuaj yeem ncav cuag 2000 W / (mK) ntawm chav tsev kub, thiab thermal expansion coefficient yog li (0.86 ± 0.1) * 10-5 / K, Thiab insulated ntawm chav tsev kub.Tsis tas li ntawd, pob zeb diamond tseem muaj cov cuab yeej zoo heev, acoustic, kho qhov muag, hluav taws xob thiab tshuaj lom neeg, uas ua rau nws muaj qhov zoo ntawm cov cua kub dissipation ntawm lub zog hluav taws xob optoelectronic, uas tseem qhia tau hais tias pob zeb diamond muaj peev xwm siv tau zoo hauv tshav kub dissipation. .

Tsis tas li nano pob zeb diamond hmoov tuaj yeem siv rau cov ntaub ntawv nyuaj, lubrication, sib tsoo, thiab lwm yam.
