ʻEono ʻano o nā nanomaterial conductive thermal i hoʻohana mau ʻia

1. Nano diomand

ʻO ke daimana ka mea me ka conductivity thermal kiʻekiʻe loa i ke kūlohelohe, me kahi conductivity thermal a hiki i 2000 W / (mK) i ka mahana o ka lumi, kahi coefficient hoʻonui hoʻonui pumehana ma kahi o (0.86 ± 0.1) * 10-5 / K, a me ka hoʻonānea ma ka lumi. ka mahana. Eia kekahi, loaʻa i ka daimana ka mīkini, acoustic, optical, uila a me nā waiwai kemika maikaʻi loa, kahi e ʻike ʻia ai nā pōmaikaʻi i ka hoʻopau wela ʻana o nā pono photoelectric mana kiʻekiʻe, e hōʻike pū ana hoʻi he mana nui kā ka daimana i ka pāhana wela wela.
2. BN

ʻO ke aniani o ka hexahedral boron nitride e like me ke ʻano o ka papa graphite. He pauka keʻokeʻo ia e ʻike ʻia e ka ʻole, lubricating, maʻalahi a me ke kaupaona māmā. ʻO 2.22g / cm3 ka mānoanoa o ka mohs, ʻo 2 ka paʻa, a paʻa paʻa nā waiwai kemika. He kiʻekiʻe ke kūpale o ka huahana a hiki ke hoʻohana ʻia i ka nitrogen a i ʻole argon ma nā mahana a hiki i ka 2800 ℃. ʻAʻole ia wale kahi haʻahaʻa coefficient hoʻolahalaha pahana, akā he ʻano conductivity wela kiʻekiʻe hoʻi, ʻaʻole wale ia he alakaʻi maikaʻi o ka wela, akā he insulator uila maʻamau. ʻO ka conductivity thermal o BN he 730w / mk. ma 300K.

3. SIC

Kūleʻa ka waiwai kemika o ka silicon carbide, a ʻoi aku ka maikaʻi o kāna conductivity ma mua o nā mea hoʻopihapiha semiconductor, a ʻoi aku ka nui o kāna conductivity thermal ma mua o ka metala i ka mahana o ka lumi. Ua hoʻopaʻa nā kānaka noiʻi mai ke Kulanui o Chemical Technology o Beijing i ka conductivity pumehana o ka alumina a me ka silicon carbide. ke kinikini silikone i hoʻoikaika ʻia. Hōʻike nā hopena i ka hoʻonui ʻana o ka conductivity thermal o ka pīpī pīpī me ka hoʻonui ʻana o ka nui o ka silicon carbide. Me ka nui o ka silicon carbide, ʻo ka conductivity thermal o ka silicon rubber i hoʻonui ʻia me ka huna liʻiliʻi liʻiliʻi ʻoi aku ka nui o ka nui o ka huna. .

4. ALN

ʻO ka aluminika nitride he aniani ʻĀtoma a hiki ke noho paʻa ma ka mahana wela o 2200. Me ka conductivity mehana maikaʻi a me ka liʻiliʻi coefficient o ka hoʻonui ʻana o ka mehana, he hopena hopena hoʻopilikia wela maikaʻi. ʻO ka conductivity thermal o ka nitride alumini ʻo 320 W · (m · K) -1, kahi kokoke i ka conductivity thermal o boron oxide a silikona carbide a ʻoi aku ma mua o 5 mau manawa o ka alumina.
Noi kuhikuhi: thermal silica gel system, thermal plastic system, thermal epoxy resin system, thermal ceramic huahana.

5. AL2O3

ʻO Alumina kahi ʻano mea hoʻopihapiha inorganic multi-functional, me ka conductivity nui wela, paʻa mau o ka dielectric a me ke kūpaʻa maikaʻi o ka lole, hoʻohana ākea ʻia i nā mea hoʻohui lahilahi, e like me ka silica gel, sealant potting, epoxy resin, plastic, rubber heat conductivity, thermal conductivity plastic. , aila silika, nā pāheheheʻe hoʻoneʻe wela a me nā mea pono ʻē aʻe. I ka noi kūpono, hiki ke hoʻohana wale ʻia ka mea hoʻopihapiha Al2O3 a i kāwili ʻia paha me nā mea hoʻopihapiha e like me AIN, BN, etc.

6. Kalepona Nanotubes

ʻO ka conductivity thermal o carbon nanotubes he 3000 W · (m · K) -1, 5 mau manawa o ke keleawe. Hiki i nā carbon nanotubes ke hoʻomaikaʻi i ka conductivity mehana, conductivity a me nā waiwai o ke kāpili, a ʻoi aku ka maikaʻi a me ka conductivity thermal ma mua o ka kuʻuna. nā mea hoʻopihapiha e like me ke kalapona kalapona, kalapona puluniu a me nā aniani puluniu.
