ʻEono ʻano o nā nanomaterial conductive thermal maʻamau
1. Nano diomand
ʻO ka daimana ka mea me ka thermal conductivity kiʻekiʻe loa i 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. temperature.In addition, daimana no hoi i maikai loa mechanical, acoustic, optical, uila a me ka kemikala waiwai, i ka mea i maopopo pono i ka wela dissipation o kiʻekiʻe-mana photoelectric mea, e hoike mai ana i ka daimana i nui noi hiki i ka wela dissipation kahua.
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 hoʻonuiʻana i 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 hopena maikaʻi ka 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 loko o nā mea hoʻohui hui, 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 mea 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 a me ka conductivity thermal ma mua o nā kuʻuna. nā mea hoʻopihapiha e like me ka ʻeleʻele kalapona, ka fiber kalapona a me ka fiber aniani.
