Waqti ka hor, cilmi-baarayaasha Kuuriyada Koonfureed ayaa naqshadeeyay nooc cusub oo nanocomposite ah: isticmaalkananodiamond(nanodiamond, ND) graphene hybrid (graphene nanoplatelets, GNPs) si loogu diyaariyo agabka nanocomposite (ND@GNPs), oo leh buuxinta noocaan ah ee lagu adkeynayo resin epoxy (EP) matrix si loogu diyaariyo walxo isku dhafan heerkulbeegyo leh astaamo jireed oo xasilloon iyo kulayl wanaagsan, kuwaas oo loo isticmaali karo warshadaha elektiroonigga ah iyo kuwa baabuurta.

Dhaqdhaqaaqa kulaylka ee alaabta polymer-ku-saleysan ayaa fure u ah ballaarinta codsigeeda.Natiijooyinka cilmi-baaristu waxay muujinayaan in isku-darka walxaha dhoobada ah sida boron nitride, silicon carbide, alumina ay si weyn u wanaajiso heerkulka kulaylka ee walxaha isku dhafan, laakiin waxqabadka buuxinta kaarboon-ku-salaysan ayaa ka fiican.Nano-diamond wuxuu wanaajin karaa kulaylka wareejinta iyo kala daadinta kulaylka, wuxuuna sidoo kale kordhin karaa isdhexgalka interface wuxuuna hagaajin karaa sifooyinka heerkulbeegga ee walxaha isku dhafan.
Tijaabooyin, kooxdu waxay doorteen nanodiamonds oo leh cabbir qayb ka yar 1μm iyo nanosheets graphene oo leh dhumuc ka yar 100nm ee isku-dhafka, ka dibna waxay ku kala firdhiyeen walxaha isku dhafan ee matrix resin epoxy at 20 wt% (fiirinta ballaaran), taas oo wanaajisay conductivity kaamerada 1231%.Ma jiro koox nano-dheeman nano-dheeman ah oo kala soocan oo lagu arkay xabagta kuleyliyaha leh, taasoo muujineysa in nano-dheeman nano-clusters iyo GNPs ay leeyihiin xoog isku xira oo adag.

 

Warqadda waxaa lagu daabacay dabeecadda ciwaanka "Saameynta kuleyliyaha nanodiamond-ka-dhex-galka graphite nanoplatelet ee isku-dhafka heerkulbeegga leh awoodda maaraynta kulaylka sare".

Nanoparticles dheeman, cabbirka <10nm, 99%+, wareegsan.Nala soo xidhiidh tijaabada hore.
