Uburyo bwa chimique bwabanje okiside grafite muri okiside ya grafite na okiside ya reaction, kandi ikongerera umwanya murwego rwo kwinjiza ogisijeni irimo amatsinda akora kuri atome ya karubone hagati ya grafite, bityo bikagabanya imikoranire hagati yabyo.

Okiside isanzwe

Uburyo bukubiyemo uburyo bwa Brodie, uburyo bwa Staudenmaier nuburyo bwa Hummers [40]. Ihame nukuvura grafite mbere na acide ikomeye,

Noneho shyiramo okiside ikomeye kugirango okiside.

Okiside ya grafite yambuwe na ultrasonic kugirango ikore graphene oxyde, hanyuma igabanuke wongeyeho kugabanya agent kugirango ubone graphene.

Ibikoresho bigabanya bisanzwe birimo hydrazine hydrate, NaBH4 hamwe no kugabanya alkali ultrasonic. NaBH4 ihenze kandi byoroshye kugumana element B,

Nubwo kugabanuka kwa alkali ultrasonic byoroshye kandi byangiza ibidukikije, biragoye kugabanya *, kandi umubare munini wamatsinda ya ogisijeni azaguma nyuma yo kugabanuka,

Kubwibyo, hydrazine hydrat ihendutse ikoreshwa muburyo bwo kugabanya okiside ya grafite. Ibyiza byo kugabanya hydratine hydratine ni uko hydratine hydrat ifite ubushobozi bwo kugabanya imbaraga kandi byoroshye guhindagurika, bityo ntihazabaho umwanda usigaye mubicuruzwa. Muburyo bwo kugabanya, amazi akwiye ya amoniya akunze kongerwaho kugirango yongere ubushobozi bwo kugabanya hydratine hydratine,

Kurundi ruhande, irashobora gutuma ubuso bwa graphene bwisubiraho bitewe nuburemere bubi, bityo bikagabanya agglomeration ya graphene.

Gutegura kwinshi kwa graphene birashobora kugerwaho hakoreshejwe uburyo bwa okiside ya chimique no kugabanya, kandi ibicuruzwa biva hagati ya graphene oxyde bifite ikwirakwizwa ryiza mumazi,

Biroroshye guhindura no gukora graphene, ubwo buryo rero bukoreshwa kenshi mubushakashatsi bwibikoresho hamwe no kubika ingufu. Ariko kubera okiside

Kubura kwa atome zimwe na zimwe za karubone mugikorwa cya ultrasonic hamwe nibisigisigi byamatsinda arimo ogisijeni ikora mugikorwa cyo kugabanya akenshi bituma graphene yakozwe irimo inenge nyinshi, igabanya imikorere yayo, bityo bikagabanya ikoreshwa ryayo murwego rwa graphene hamwe nibisabwa byujuje ubuziranenge. .
