Izinhlobo eziyisithupha zama-nanomaterial wokushisa asetshenziswa kakhulu

1. Nano diomand

IDayimane iyinto ephethe ukuqhutshwa kokushisa okushisayo okuphezulu kunayo yonke, ngokuqhutshwa kokushisa okushisayo okufika ku-2000 W / (mK) ekamelweni lokushisa, isilinganiso sokukhulisa esishisayo cishe (0.86 ± 0.1) * 10-5 / K, kanye nokufakwa ekamelweni i-temperature.Ukungezelela, idayimane libuye libe nezakhiwo ezinhle kakhulu zemishini, i-acoustic, i-optical, ugesi namakhemikhali, okwenza libe nezinzuzo ezisobala ekushisweni kokushisa kwamadivayisi we-photoelectric anamandla amakhulu, okukhombisa nokuthi idayimane linamandla amakhulu okusebenzisa emkhakheni wokushiswa kokushisa.
2. I-BN

Isakhiwo se-crystal se-hexahedral boron nitride siyefana nesakhiwo sesendlalelo se-graphite. It is a powder emhlophe ebonakala okuxekethile, ukuthambisa, ukumuncwa okulula nesisindo esincane.Ukuqina kwethiyori kungu-2.29g / cm3, ukuqina kwe-mohs kungu-2, futhi izakhiwo zamakhemikhali zizinzile kakhulu.Umkhiqizo unokumelana okuphezulu komswakama futhi ungasetshenziswa ku-nitrogen noma i-argon emazingeni okushisa afinyelela ku-2800 It .Akukhona nje kuphela ukuthi inenani eliphansi lokunweba lokushisa, kepha futhi ine-conductivity ephezulu yokushisa, akuyona nje kuphela umqhubi omuhle wokushisa, kepha i-insulator evamile kagesi. Ukuqhutshwa kokushisa kwe-BN kwakungu-730w / mk. ngo-300K.

3. SIC

Impahla yamakhemikhali ye-silicon carbide izinzile, futhi ukuqhutshwa kwayo okushisayo kungcono kunezinye izinto ezigcwalisa ama-semiconductor, futhi ukuqhutshwa kwayo okushisayo kukhulu kakhulu kunensimbi ekamelweni lokushisa.Abaphenyi abavela eBeijing University of Chemical Technology bafunde ukuqhutshwa kokushisa kwe-alumina ne-silicon carbide i-silicone irabha eqinisiwe.Imiphumela ikhombisa ukuthi ukuqhutshwa okushisayo kwenjoloba abicah kuyanda ngokwanda kwenani le-silicon carbide.Nenani elifanayo le-silicon carbide, ukuqhutshwa okushisayo kwenjoloba ye-silicon eqiniswe ngosayizi wezinhlayiyana ezincane kukhulu kunosayizi wezinhlayiyana ezinkulu .

4. ALN

I-Aluminium nitride iyi-crystal ye-athomu futhi ingaba khona kahle emazingeni okushisa aphezulu angama-2200 ℃. Nge-conductivity enhle yokushisa kanye ne-coefficient encane yokukhula okushisayo, kuyinto enhle yokushisa ukushisa.Ukuqhutshwa okushisayo kwe-aluminium nitride yi-320 W · (m · K) -1, esondelene nokushisa okushisayo kwe-boron oxide futhi i-silicon carbide futhi izikhathi ezingaphezu kwezingu-5 ze-alumina.
Ukuqondiswa kwesicelo: uhlelo lwe-silica gel olushisayo, uhlelo lwepulasitiki olushisayo, uhlelo lwe-epoxy resin elishisayo, imikhiqizo ye-ceramic eshisayo.

5. AL2O3

I-Alumina uhlobo lokugcwalisa okungaxutshiwe okuhlukahlukene, okunokuqhutshwa okukhulu kokushisayo, ukumelana nokugqoka okungagudluki, okusetshenziswa kakhulu ezintweni eziyinhlanganisela zenjoloba, njenge-silica gel, potting sealant, epoxy resin, ipulasitiki, injoloba yokushisa okushisayo, ipulasitiki yokuhambisa okushisayo , i-silicone grease, i-heat dissipation ceramics kanye nezinye izinto ezisetshenziswayo.Kuhlelo lokusebenza olusebenzayo, i-Al2O3 filler ingasetshenziswa yodwa noma ixutshwe nokunye okugcwalisa njenge-AIN, BN, njll.

6. Carbon Nanotubes

Ukuqhutshwa kokushisa kwama-carbon nanotubes kungu-3000 W · (m · K) -1, izikhathi eziphindwe ka-5 kulezo zethusi. Ama-nanotubes e-Carbon angathuthukisa kakhulu ukuqhutshwa kokushisa, ukuqhuba kanye nezakhiwo zenjoloba, futhi ukuqiniswa kwayo nokuqhuba okushisayo kungcono kunokwendabuko okugcwalisa okufana ne-carbon black, i-carbon fiber kanye ne-fiber fiber.
