ʻEono ʻano o nā nanomaterial conductive thermal maʻamau

1. Nano diomand

ʻO ka daimana ka mea me ka thermal conductivity kiʻekiʻe loa ma ke ʻano, me ka conductivity thermal a hiki i 2000 W / (mK) ma ka lumi wela, kahi koena hoʻonui wela o kahi (0.86±0.1) * 10-5/K, a me ka insulation ma ka lumi. ʻOi aku ka maikaʻi o ka mīkini, acoustic, optical, uila a me nā waiwai kemika, kahi e loaʻa ai nā pōmaikaʻi i ka hoʻokuʻu ʻana i ka wela o nā mana photoelectric kiʻekiʻe, e hōʻike ana hoʻi i ka daimana i ka nui o ka hoʻohana ʻana i ka māla wela.
2. BN

ʻO ke ʻano aniani o ka boron nitride hexahedral ua like ia me ka ʻano o ka papa graphite.He pauka keʻokeʻo ia i ʻike ʻia e ka hemo, lubricating, maʻalahi absorption a me ke kaumaha māmā. Theoretical density ʻo 2.29g / cm3, mohs hardness he 2, a ʻo nā waiwai kemika he kūpaʻa loa. argon ma nā mahana a hiki i 2800 ℃. ʻAʻole ia he haʻahaʻa haʻahaʻa hoʻonui hoʻonui haʻahaʻa, akā he kiʻekiʻe thermal conductivity, ʻaʻole wale he conductor maikaʻi o ka wela, akā he insulator uila maʻamau. ʻO ka conductivity thermal o BN he 730w / mk ma 300K.

3. SIC

He kūpaʻa ka waiwai kemika o ka carbide silika, a ʻoi aku ka maikaʻi o kāna conductivity thermal ma mua o nā mea hoʻopiha semiconductor ʻē aʻe, a ʻoi aku ka nui o kāna conductivity thermal ma mua o ke metala ma ka lumi lumi. ʻO nā hualoaʻa e hōʻike ana i ka piʻiʻana o ka thermal conductivity o ka silicone rubber me ka hoʻonuiʻia o ka nui o ka silicon carbide. .

4. ALN

ʻO ka nitride alumini he aniani atomika a hiki ke noho paʻa i ka wela kiʻekiʻe o 2200 ℃.Me ka maikaʻi o ka thermal conductivity a me ka liʻiliʻi liʻiliʻi o ka hoʻonui ʻana i ka wela, he mea maikaʻi ka hopena wela. carbide silika a ʻoi aku ma mua o 5 mau manawa o ka alumina.
Ke kuhikuhi noi: ʻōnaehana silica gel wela, ʻōnaehana plastic thermal, ʻōnaehana epoxy resin thermal, nā huahana ceramic thermal.

5. AL2O3

ʻO ka alumina kahi ʻano mea hoʻopihapiha inorganic multi-functional, me ka conductivity thermal nui, dielectric mau a ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka pale ʻana, hoʻohana nui ʻia i nā mea hoʻohui pūlima, e like me ka silica gel, potting sealant, epoxy resin, plastic, rubber thermal conductivity, thermal conductivity plastic , silicone grease, heat dissipation ceramics a me nā mea ʻē aʻe. Ma ka hoʻohana pono ʻana, hiki ke hoʻohana wale ʻia ka hoʻopihapiha Al2O3 a i hui pū ʻia me nā mea hoʻopihapiha ʻē aʻe e like me AIN, BN, etc.

6.ʻO Carbon Nanotubes

ʻO ka thermal conductivity o carbon nanotubes he 3000 W · (m · K) -1, 5 mau manawa o ka copper.Carbon nanotubes hiki ke hoʻomaikaʻi nui i ka conductivity thermal, conductivity a me nā waiwai kino o ka lāʻau, a ʻoi aku ka maikaʻi o kona hoʻoikaika ʻana a me ka thermal conductivity. nā mea hoʻopihapiha e like me ke kalapona ʻeleʻele, ke kalapona kalapona a me ke aniani aniani.
