I kekahi manawa i hala aku nei, ua hoʻolālā nā mea noiʻi o South Korea i kahi ʻano nanocomposite hou: ka hoʻohana ʻana onanodiamond(nanodiamond, ND) hybrid graphene (graphene nanoplatelets, GNPs) e hoʻomākaukau i nā mea nanocomposite (ND@GNPs), me kēia ʻano mea hoʻopihapiha Hoʻoikaika i ka epoxy resin (EP) matrix e hoʻomākaukau i nā mea hoʻohui thermoset me nā waiwai kino kūpaʻa a me ka conductivity thermal maikaʻi loa, hiki ke hoʻohana ʻia i nā ʻoihana uila a me nā ʻoihana automotive.
ʻO ka conductivity thermal o nā mea polymer-based ke kī i kāna hoʻonui noi.Hōʻike nā hopena noiʻi ʻo ka hoʻohui ʻana o nā mea hoʻopihapiha ceramic e like me boron nitride, silicon carbide, a me alumina e hoʻomaikaʻi nui i ka conductivity thermal o ka mea hoʻohui, akā ʻoi aku ka maikaʻi o ka hana o kēia mea hoʻopiha kalapona.Hiki i ka Nano-diamond ke hoʻoikaika i ka hoʻoili wela a me ka hoʻopau ʻana i ka wela, a hiki ke hoʻonui i ka pilina pili a hoʻomaikaʻi i nā waiwai thermophysical o nā mea hoʻohui.
Ma o nā hoʻokolohua, ua koho ka hui i nā nanodiamonds me ka nui o ka liʻiliʻi ma lalo o 1μm a me ka graphene nanosheets me ka mānoanoa o ka liʻiliʻi ma mua o 100nm no ka hybridization, a laila hoʻopuehu i ka mea hoʻohui i loko o kahi epoxy resin matrix ma 20 wt% (mass concentration), i hoʻomaikaʻi ʻia. ka thermal conductivity 1231%.ʻAʻole i ʻike ʻia nā nano-diamond nano-clusters i hoʻokaʻawale ʻia ma ka thermally conductive adhesive, e hōʻike ana i ka nano-diamond nano-clusters a me nā GNPs he ikaika paʻa paʻa.
Ua paʻi ʻia ka pepa ma ke ʻano me ke poʻo inoa "Implication of thermally conductive nanodiamond-interspersed graphite nanoplatelet hybrids in thermoset composites with superior thermal management capability".
ʻO nā nanoparticles daimana, nui <10nm, 99%+, Poʻe.E kelepona iā mākou no ka hoʻāʻo mua.
