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. Ukongeza, idayimani ikwanayo nomatshini obalaseleyo, i-acoustic, i-optical, umbane kunye neekhemikhali iipropathi, nto leyo eyenza ukuba ibe neengenelo ezicacileyo ekutshatyalalisweni kobushushu bamandla aphezulu. izixhobo photoelectric, nto leyo ikwabonisa ukuba idayimani inamandla kakhulu isicelo kwibala lokuchitha ubushushu.
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 obushushu ukuya kuthi ga kwi-2800 ℃. i-conductivity, ayikho nje i-conductor efanelekileyo yokushisa, kodwa i-insulator yombane eqhelekileyo.I-thermal conductivity ye-BN yayingu-730w / mk kwi-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. Irabha ye-silicone eyomeleziweyo Umlinganiselo ofanayo we-silicon carbide, i-thermal conductivity ye-rubber ye-silicon eyomelezwe ngesayizi ye-particle encinci inkulu kunobukhulu be-particle enkulu.

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 yokulahla ubushushu kunye nezinye izinto.Kwisicelo esisebenzayo, i-Al2O3 filler ingasetyenziswa yodwa okanye ixutywe kunye nezinye izihluzi. njenge-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.
