Oge ụfọdụ gara aga, ndị na-eme nchọpụta South Korea haziri ụdị ihe ọhụrụ nanocomposite: ojiji nkenanodiamond(nanodiamond, ND) ngwakọ graphene (graphene nanoplatelets, GNPs) iji kwadebe nanocomposite ihe (ND @ GNPs), na ụdị filler Toughening na epoxy resin (EP) matrix iji kwadebe thermoset mejupụtara ihe nwere anụ ahụ kwụsiri ike na ezigbo thermal conductivity, nke enwere ike iji ya na ngwa eletrọnịkị na ụlọ ọrụ ụgbọ ala.
Nrụpụta ọkụ nke ihe ndị dabere na polymer bụ isi ihe na-eme ka mgbasawanye ngwa ya.Nsonaazụ nyocha na-egosi na mgbakwunye nke ihe ndị na-eme ihe dị ka seramiiki dị ka boron nitride, silicon carbide, na alumina na-eme ka nrụpụta thermal conductivity nke ihe mejupụtara ya na-eme ka ọ dịkwuo mma, mana arụmọrụ nke ihe mkpuchi carbon a ka mma.Nano-diamond nwere ike ịkwalite mbufe ọkụ na mgbasa ọkụ, ma nwee ike ịbawanye mmekọrịta interface ma melite njirimara thermophysical nke ihe ndị mejupụtara.
Site na nnwale, ndị otu ahụ họrọ nanodiamonds nwere urughuru nke na-erughị 1μm na graphene nanosheets nwere ọkpụrụkpụ nke na-erughị 100nm maka hybridization, wee chụsasịa ihe mejupụtara ya na matrix epoxy resin na 20 wt% (ọnụọgụ oke), nke mere ka mma. Thermal conductivity 1231%.Ọnweghị ụyọkọ nano-diamond nano-ụyọkọ achọpụtara na nrapado na-ekpo ọkụ, na-egosi na nano-diamond nano-clusters na GNP nwere ike njikọ siri ike.
E bipụtara akwụkwọ akụkọ ahụ na ọdịdị ya na aha "Mmetụta nke thermally conductive nanodiamond-interspersed graphite nanoplatelet hybrids na thermoset composites na elu thermal management ikike".
Ihe ndị dị na diamond, nha <10nm, 99%+, Spherical.Kpọtụrụ anyị maka ule mbụ.
