3)Ọdịiche dị n'etiti graphite gbasaa na graphene
Graphene na graphite gbasaa nwere arụmọrụ dị iche iche na nhazi ihe yana mpaghara ngwa.Enwere ike iji graphite gbasaa dị ka akụrụngwa maka mmepụta graphene.Dịka ọmụmaatụ, enwere ike iji usoro Hummers nweta graphene oxide site na mgbasawanye ultrasonic nke graphite oxide.Mgbe a na-ewepụ graphite gbasaa n'ime otu ibe, ọ na-aghọ graphene.Ọ bụrụ na a na-eyipụ ya n'ọtụtụ ọkwa, ọ bụ graphene ole na ole.Enwere ike ịkwadebe nanosheets graphene site na ihe karịrị iri ruo 30.
4) Mpaghara ngwa bara uru nke graphite gbasaa
1. Ngwa nke ngwa ahụike
Uwe ahụike nke graphite gbasaa nwere ike dochie ọtụtụ gauze ọdịnala n'ihi ọtụtụ ihe mara mma.
2. Ngwa nke ngwa agha
A na-egweri graphite gbasaa ka ọ bụrụ ntụ ntụ dị mma, nke nwere àgwà ịgbasa siri ike na absorption na ebili mmiri infrared.Ime ntụ ntụ ya dị mma ka ọ bụrụ ihe mkpuchi infrared mara mma na-arụ ọrụ dị mkpa na ihe mgbochi fotoelectric na agha ọgbara ọhụrụ.
3. Ngwa nke ihe nchebe gburugburu ebe obibi
A na-eji graphite gbasaa n'ọtụtụ ebe n'ọhịa nke nchebe gburugburu ebe obibi n'ihi njupụta ya dị ala, nke na-adịghị egbu egbu, enweghị mmetọ, ọgwụgwọ dị mfe na mgbasa ozi dị mma.
4. Ihe ndi ozo
Ngwongwo carbon nwere ndakọrịta nke ọma na ahụ mmadụ ma bụrụ ezigbo akụrụngwa biomedical.Dị ka ụdị carbon ọhụrụ, ihe graphite gbasasịrị nwere njirimara mgbasa ozi mara mma maka macromolecules organic na biological.Ọ nwere ezigbo biocompatibility, adịghị egbu egbu, enweghị ụtọ na enweghị mmetụta ọ bụla.Ọ nwere atụmanya ngwa sara mbara na ngwa biomedical.
