Iindidi ezintandathu ze-thermal conductive nanomaterials eziqhele ukusetyenziswa

1. Nano diomand

Idayimani yimathiriyeli enowona mgangatho uphezulu we-thermal conductivity kwindalo, kunye ne-thermal conductivity ukuya kwi-2000 W / (mK) kwiqondo lokushisa, i-coefficient yokwandisa i-thermal malunga (0.86± 0.1) * 10-5 / K, kunye nokugquma kwigumbi. Iqondo lokushisa.Ukongezelela, idayimani nayo inomatshini obalaseleyo, i-acoustic, i-optical, umbane kunye neempawu zemichiza, eyenza ibe neenzuzo ezicacileyo ekutshitshisweni kobushushu bezixhobo eziphezulu zombane we-photoelectric, nto leyo ebonisa ukuba idayimani inamandla okusebenza kwintsimi yokutshatyalaliswa kobushushu.
2. BN

Ubume bekristale be-hexahedral boron nitride bufana nesakhiwo se-graphite layer.Ingumgubo omhlophe obonakaliswe ngokukhululeka, ukuthambisa, ukufunxa lula kunye nobunzima obulula.Uxinaniso lwethiyori yi-2.29g / cm3, ubunzima be-mohs yi-2, kunye neempawu zeekhemikhali zizinzile kakhulu.Imveliso inokumelana nomswakama ophezulu kwaye ingasetyenziselwa kwi-nitrogen okanye i-argon kumaqondo okushisa ukuya kwi-2800 ℃.Ayinayo nje i-coefficient yokwandisa i-thermal ephantsi, kodwa ine-conductivity ephezulu ye-thermal, ayikho nje i-conductor efanelekileyo yokushisa, kodwa i-insulator yombane eqhelekileyo.I-thermal conductivity ye-BN yayingu-730w / mk nge 300k.

3. I-SIC

Ipropathi yekhemikhali ye-silicon carbide izinzile, kwaye i-thermal conductivity yayo ingcono kunezinye iifayili ze-semiconductor, kwaye i-thermal conductivity yayo ingaphezulu kunentsimbi kwiqondo lokushisa. Iziphumo zibonisa ukuba irubha ye-silicone yerubha inyuka ngokunyuka kwexabiso le-silicon carbide. Ngomlinganiselo ofanayo we-silicon carbide, i-thermal conductivity ye-rubber ye-silicon eqiniswe ngesayizi encinci ye-particle inkulu kune-particle particle size. .

4. ALN

I-Aluminiyam nitride yikristale yeathom kwaye ingabakho ngokuzinzileyo kubushushu obuphezulu obuyi-2200 ℃.Ngokuhamba kakuhle kwe-thermal kunye ne-coefficient encinci yokwandiswa kwe-thermal, yinto efanelekileyo yokumelana nobushushu. i-silicon carbide kunye namaxesha angaphezu kwama-5 e-alumina.
Ulwalathiso lwesicelo: inkqubo ye-silica gel ye-thermal, inkqubo yeplastiki ye-thermal, inkqubo ye-thermal epoxy resin, iimveliso ze-ceramic ezishisayo.

5. AL2O3

I-alumina luhlobo lwe-multi-functional inorganic filler, ene-thermal conductivity enkulu, i-dielectric engaguqukiyo kwaye ingcono ukumelana nokunxiba, isetyenziswa ngokubanzi kwizinto ezixutywe zerabha, njenge-silica gel, i-potting sealant, i-epoxy resin, iplastiki, i-rubber conductivity ye-thermal conductivity, iplastiki ye-thermal conductivity. , igrisi ye-silicone, i-ceramics yokutshatyalaliswa kobushushu kunye nezinye izinto.Kwisicelo esisebenzayo, i-Al2O3 filler ingasetyenziswa yodwa okanye ixutywe kunye nezinye izizaliso ezifana ne-AIN, BN, njl.

6.IiNanotubes zeCarbon

I-thermal conductivity ye-carbon nanotubes yi-3000 W · (m·K) -1, amaxesha ama-5 okobhedu.I-Carbon nanotubes inokuphucula kakhulu i-conductivity ye-thermal, i-conductivity kunye neempawu ezibonakalayo ze-rubber, kunye nokuqiniswa kwayo kunye ne-thermal conductivity kungcono kunendabuko. izihluzi ezifana nekhabhoni emnyama, i-carbon fiber kunye ne-glass fiber.
