Iyo kemikari nzira inotanga oxidize graphite kuita graphite oxide kuburikidza neoxidation reaction, uye inowedzera denderedzwa nekuisa mweya weokisijeni ine mashandiro emapoka pamaatomu ekabhoni pakati pezvikamu zvegraphite, zvichibva zvaita kuti kudyidzana pakati pezvikamu.

Common oxidation

Nzira idzi dzinosanganisira nzira yeBrodie, nzira yeStaudenmaier uye nzira yeHummers [40].Nheyo yacho ndeyekurapa graphite neasidhi yakasimba kutanga,

Wobva wawedzera oxidant yakasimba yeoxidation.

Iyo oxidized graphite inobviswa ne ultrasonic kugadzira graphene oxide, uye yozoderedzwa nekuwedzera kuderedza agent kuti iwane graphene.

Kazhinji kuderedza vamiririri vanosanganisira hydrazine hydrate, NaBH4 uye yakasimba alkali ultrasonic kuderedza.NaBH4 inodhura uye iri nyore kuchengeta chinhu B,

Kunyangwe iyo yakasimba alkali ultrasonic kuderedzwa iri nyore uye inoshamwaridzana nemhoteredzo, zvakaoma kuderedza *, uye nhamba huru yeoksijeni inoshanda mapoka acharamba ari mushure mekuderedzwa,

Naizvozvo, yakachipa hydrazine hydrate inowanzoshandiswa kuderedza graphite oxide.Kubatsira kwe hydrazine hydrate kuderedza ndeyokuti hydrazine hydrate ine simba rakasimba rekudzikisa uye iri nyore kuputika, saka hapazovi nekusvibiswa kwakasara muchigadzirwa.Mukuita kwekudzikisa, huwandu hwakakodzera hwemvura yeammonia inowanzowedzerwa kuvandudza kugona kwekudzikisa kwehydrazine hydrate,

Kune rimwe divi, inogona kuita kuti mapeji egraphene adzorere mumwe nemumwe nekuda kwekupokana kwakashata, nekudaro kuderedza kuunganidzwa kwegraphene.

Kugadzirira kwakakura kwegraphene kunogona kuwanikwa nemakemikari oxidation uye nzira yekudzikisa, uye yepakati chigadzirwa graphene oxide ine yakanaka kupararira mumvura,

Zviri nyore kugadzirisa uye kuita graphene, saka nzira iyi inowanzoshandiswa mukutsvagisa kwezvinhu zvinoumbwa uye kuchengetedza simba.Asi nekuda kwe oxidation

Kusavapo kwemamwe maatomu ekabhoni mu ultrasonic process uye zvakasara zveokisijeni-ine mashandiro emapoka mukuderedza maitiro anowanzoita kuti graphene inogadzirwa ive nehurema hwakawanda, iyo inoderedza conductivity yayo, nekudaro ichimisa kushanda kwayo mumunda wegraphene nemhando yepamusoro zvinodiwa. .
