ʻO ke ʻano kemika e hoʻoheheʻe mua i ka graphite i graphite oxide ma o ka oxidation reaction, a hoʻonui i ka spacing layer ma ka hoʻokomo ʻana i ka oxygen i loko o nā hui hana ma nā ʻātoma kalapona ma waena o nā papa graphite, a laila e hoʻonāwaliwali ai ka pilina ma waena o nā papa.

ʻOkiona maʻamau

Aia nā ʻano hana i ke ala Brodie, ke ʻano Staudenmaier a me ke ʻano Hummers [40].ʻO ke kumumanaʻo e mālama mua i ka graphite me ka waikawa ikaika,

A laila e hoʻohui i ka oxidant ikaika no ka oxidation.

Wehe ʻia ka graphite oxidized e ka ultrasonic e hana i ka graphene oxide, a laila hoʻemi ʻia ma ka hoʻohui ʻana i ka mea hoʻemi e loaʻa ai ka graphene.

ʻO nā mea hoʻohaʻahaʻa maʻamau ka hydrazine hydrate, NaBH4 a me ka hoʻohaʻahaʻa ultrasonic alkali ikaika.He pipiʻi a maʻalahi ka NaBH4 e mālama i ka mea B,

ʻOiai he mea maʻalahi ka hoʻohaʻahaʻa ultrasonic alkali ikaika a me ke kaiapuni, he paʻakikī ke hōʻemi *, a e mau ka nui o nā hui hana oxygenated ma hope o ka hoʻemi ʻana.

No laila, hoʻohana mau ʻia ka hydrazine hydrate e hōʻemi i ka graphite oxide.ʻO ka pōmaikaʻi o ka hydrazine hydrate reduction ʻo ia ka hydrazine hydrate he ikaika hoʻohaʻahaʻa ikaika a maʻalahi hoʻi e volatilize, no laila ʻaʻohe mea haumia i koe i ka huahana.I ke kaʻina hana hoʻohaʻahaʻa, hoʻohui pinepine ʻia ka nui o ka wai ammonia e hoʻomaikaʻi i ka hiki ke hoʻemi o ka hydrazine hydrate,

Ma ka ʻaoʻao ʻē aʻe, hiki iā ia ke hana i nā ʻili o ka graphene e hoʻokuʻu kekahi i kekahi ma muli o nā hoʻopiʻi maikaʻi ʻole, a laila e hōʻemi i ka agglomeration o ka graphene.

Hiki ke ʻike ʻia ka hoʻomākaukau nui ʻana o ka graphene e ka oxidation kemika a me ke ʻano hoʻohaʻahaʻa, a ʻo ka huahana waena o ka graphene oxide i hoʻopuehu maikaʻi i ka wai,

He maʻalahi ke hoʻololi a hoʻohana i ka graphene, no laila hoʻohana pinepine ʻia kēia ʻano i ka noiʻi ʻana i nā mea hoʻohuihui a me ka mālama ʻana i ka ikehu.Akā, no ka oxidation

ʻO ka nele o kekahi mau kalapona kalapona i ke kaʻina kani ultrasonic a me ke koena o ka oxygen i loaʻa nā hui hana i loko o ka hoʻohaʻahaʻa kaʻina hana pinepine i ka graphene i hana ʻia i loko o nā hemahema, e hōʻemi ana i kona conductivity, no laila e kaupalena ana i kāna noi ma ke kahua o ka graphene me nā koi kiʻekiʻe. .
