Kale, ofufuza aku South Korea adapanga mtundu watsopano wazinthu za nanocomposite: kugwiritsa ntchitonanodiamond(nanodiamond, ND) wosakanizidwa graphene (graphene nanoplatelets, GNPs) kukonzekera zipangizo nanocomposite (ND@GNPs), ndi mtundu wa filler Toughening the epoxy utomoni (EP) masanjidwewo kukonzekera thermoset gulu zipangizo ndi khola thupi katundu ndi madutsidwe kwambiri matenthedwe matenthedwe, zomwe zitha kugwiritsidwa ntchito m'mafakitale amagetsi ndi magalimoto.

Kutentha kwamafuta azinthu zopangidwa ndi polima ndiye chinsinsi chakukula kwa ntchito yake.Zotsatira za kafukufuku zikuwonetsa kuti kuwonjezera kwa ma ceramic particle fillers monga boron nitride, silicon carbide, ndi alumina kumathandizira kwambiri matenthedwe azinthu zophatikizika, koma magwiridwe antchito a carbon-based filler ndiabwinoko.Nano-diamond imatha kupititsa patsogolo kutentha ndi kutayika kwa kutentha, komanso kuonjezera kuyanjana kwa mawonekedwe ndikusintha mawonekedwe a thermophysical azinthu zophatikizika.
Kudzera zatsopano, gulu anasankha nanodiamonds ndi tinthu kukula zosakwana 1μm ndi graphene nanosheets ndi makulidwe zosakwana 100nm kwa hybridization, ndiyeno anabalalitsa gulu zinthu mu epoxy utomoni masanjidwewo pa 20 wt% (misa ndende), amene bwino. matenthedwe madutsidwe 1231%.Palibe masango olekanitsidwa a nano-diamond nano-clusters omwe adapezeka pa zomatira zotenthetsera, zomwe zikuwonetsa kuti ma nano-diamond nano-clusters ndi ma GNPs ali ndi mphamvu yomangiriza.

 

Pepala linasindikizidwa pa chilengedwe ndi mutu wakuti "Tanthauzo la thermally conductive nanodiamond-interspersed graphite nanoplatelet hybrids mu thermoset composites ndi apamwamba matenthedwe kasamalidwe mphamvu".

Diamondi nanoparticles, kukula <10nm, 99%+, Spherical.Lumikizanani nafe kuyesa koyambirira.
