Iindidi ezintandathu zeeanomaterials ezisetyenziswayo ezifudumeleyo

1. Nano diomand

Idayimani yinto enezinto ezishushu kakhulu zokuqhuba kwindalo, kunye ne-thermal conductivity ukuya kuthi ga kwi-2000 W / (mK) kubushushu begumbi, umlinganiso wokwandiswa kwe-thermal malunga (0.86 ± 0.1) * 10-5 / K, kunye nokugquma kwigumbi Ubushushu, ukongeza, idayimani ikwanazo iipropathi zoomatshini, ii-acoustic, i-optical, ezombane kunye neekhemikhali, ezenza ukuba zibe neenzuzo ezibonakalayo ekutshatyalalisweni kobushushu kwezixhobo zeefotoelectric ezinamandla amakhulu, ekwabonisa ukuba idayimane inokubanakho kwesicelo esikhulu kumhlaba wokutshatyalaliswa kobushushu.
2. BN

Isakhiwo se-crystal ye-hexahedral boron nitride iyafana naleyo yolwakhiwo lwegraphite. It is a umgubo emhlophe luphawulwa evakalala, ukuthambisa ajikeleze, ukufakwa lula kunye nobunzima light.Theoretical mninzi yi 2.29g / cm3, lukhuni mohs yi-2, kwaye iipropati imichiza zizinzile kakhulu.The imveliso iye ukumelana eliphezulu ukufuma kwaye ingasetyenziswa nitrogen okanye I-argon kumaqondo obushushu ukuya kuthi ga kwi-2800 It .Akuphelelanga nje ekubeni unokwanda okwaneleyo kwe-thermal, kodwa ikwanayo ne-conductivity ephezulu yokushisa, ayisiyi-conductor elungileyo yobushushu kuphela, kodwa i-insulator yombane eqhelekileyo. Ukuqhutywa kwe-thermal kwe-BN yayiyi-730w / mk. kwi-300K.

3. I-SIC

Ipropathi yekhemikhali ye-silicon carbide izinzile, kwaye ukuqhuba kwayo kwe-thermal kubhetele kunezinye izinto ezigcwalisa i-semiconductor, kwaye ukuqhuba kwayo kwe-thermal kukhulu ngakumbi kunesinyithi kubushushu begumbi. Abaphandi abavela kwiYunivesithi yaseBeijing yeChemical Technology baye bafunda ukuqhuba kwe-thermal ye-alumina kunye ne-silicon carbide Iziphumo zibonisa ukuba ukuhanjiswa kwe-rubber ye-silicone yerabha kwanda kunye nokunyuka kwemali ye-silicon carbide.Ngomlinganiselo ofanayo we-silicon carbide, ukuhanjiswa kwe-thermal ye-silicon yerabha eqiniswe ngobukhulu be-particle ubukhulu bukhulu kunokuba ubukhulu beengqungquthela .

4. ALN

I-Aluminium nitride yikristale yeatom kwaye inokubakho ngokuzinzileyo kubushushu obuphezulu be-2200 ℃. Nge-conductivity efanelekileyo ye-thermal kunye ne-coefficient encinci yokwandiswa kwe-thermal, yinto efanelekileyo yokushisa ukushisa.Ukuqhutyelwa kwe-thermal ye-aluminium nitride ngu-320 W · (m · K) -1, esondele kwi-thermal conductivity ye-boron oxide kunye lesilicon khabhayithi kwaye ngaphezulu kwamaxesha ama-5 alumina.
Ulwalathiso lwesicelo: inkqubo ye-silica ye-thermal, inkqubo yeplastiki eshushu, inkqubo ye-epoxy resin ye-thermal, iimveliso zeceramic ezishushu.

5. AL2O3

I-Alumina luhlobo lwezinto ezininzi ezisebenza ngokugcwalisa izinto ezingafunekiyo, kunye nokuqhutywa kwe-thermal enkulu, ukungqinelani kwe-dielectric rhoqo kunye nokuqina kokunxiba okungcono, okusetyenziswa kakhulu kwimpahla yerabha edityanisiweyo, enje nge-silica gel, itywina lesitywina, i-epoxy resin, iplastiki, irabha yokuqhuba kwe-thermal, iplastiki yokuqhuba kwe-thermal , i-silicone grease, i-ceramics yokutshatyalaliswa kobushushu kunye nezinye izixhobo.Ngokwesicelo esisebenzayo, i-Al2O3 i-filler ingasetyenziselwa yodwa okanye ixutywe nezinye izinto ezifana ne-AIN, BN, njl.

6. IiNanotubes zecarbon

Ukuqhutywa kwe-thermal ye-carbon nanotubes yi-3000 W · (m · K) -1, amaxesha ama-5 obhedu. I-nanotubes zecarbon zinokuphucula ngokubonakalayo ukuqhuba kwe-thermal, ukuqhuba kunye neempawu zerabha, kunye nokuqiniswa kwayo kunye ne-thermal conductivity kungcono kunakwantu iifilitha ezifana nekhabhoni emnyama, ifayibha yekhabhoni kunye nefayibha yeglasi.
