Ngexesha elidlulileyo, abaphandi baseMzantsi Korea bayile uhlobo olutsha lwezinto eziphathekayo ze-nanocomposite: ukusetyenziswa kwenanodiamond(i-nanodiamond, ND) i-graphene ye-hybrid (i-graphene nanoplatelets, i-GNPs) ukulungiselela izinto ze-nanocomposite (ND@GNPs), kunye nolu hlobo lokuzalisa Ukuchukumisa i-epoxy resin (EP) matrix ukulungiselela izinto ezidibeneyo ze-thermoset ezineempawu ezizinzileyo zomzimba kunye ne-conductivity egqwesileyo yokushisa, enokusetyenziswa kwimizi-mveliso yombane kunye neemoto.
I-thermal conductivity yezinto ezisekelwe kwi-polymer iyisitshixo sokwandiswa kwesicelo sayo.Iziphumo zophando zibonisa ukuba ukongezwa kwee-ceramic particle fillers ezifana ne-boron nitride, i-silicon carbide, kunye ne-alumina iphucula kakhulu i-thermal conductivity ye-composite material, kodwa ukusebenza kwesi sigcwalisi se-carbon-based singcono.I-Nano-diamond inokuphucula ukuhanjiswa kobushushu kunye nokuchithwa kobushushu, kwaye inokunyusa intsebenziswano ye-interface kunye nokuphucula iimpawu ze-thermophysical zezinto ezidibeneyo.
Ngokusebenzisa imifuniselo, iqela likhethe iinanodiamonds ezinobungakanani besuntswana elingaphantsi kwe-1μm kunye negraphene nanosheets ezinobunzima obungaphantsi kwe-100nm yokuxutywa, emva koko lasasaza imathiriyeli ehlanganisiweyo kwi-epoxy resin matrix kwi-20 wt% (i-mass concentration), eyaphucula. thermal conductivity 1231%.Akukho maqela ahlukeneyo e-nano-diamond nano-clusters afunyenwe kwi-adhesive conductive conductive thermally, ebonisa ukuba i-nano-diamond nano-clusters kunye ne-GNP zinamandla okubopha.
Eli phepha lapapashwa kwindalo kunye nesihloko esithi "Intsingiselo ye-thermal conductive nanodiamond-interspersed graphite nanoplatelet hybrids kwi-thermoset composite kunye nekhono lolawulo oluphezulu lwe-thermal".
Diamond nanoparticles, ubungakanani <10nm, 99%+, Spherical.Qhagamshelana nathi kuvavanyo lokuqala.
