Hauv qhov no, graphene oxide yog oxidized daim ntawv ntawm graphene. Nws muaj ib txheej atomic, laced nrog oxygen-muaj cov pab pawg ua haujlwm.
Daim duab 01: Graphene Oxide Chemical Structure
Cov khoom no yog dispersible nyob rau hauv dej thiab lwm yam kuab tshuaj vim muaj oxygen-functionalities. Yog li ntawd, nws yooj yim los ua cov khoom siv no. Tsis tas li, cov cuab yeej no tso cai rau nws los txhim kho cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm ceramic thaum peb sib xyaw cov khoom siv ceramic nrog graphene oxide. Txawm li cas los xij, nws tsis zoo rau hluav taws xob conductivity. Li no, peb categorize nws raws li ib tug hluav taws xob insulator. Feem ntau, qhov no yog vim muaj kev cuam tshuam ntawm sp2 kev sib koom tes uas muaj nyob hauv graphite. Tab sis, muaj qee cov txheej txheem uas peb tuaj yeem siv los txhawb nws cov khoom.
Tsis tas li, muaj plaub txoj hauv kev loj uas cov tuam txhab siv los ua qhov sib xyaw no. Lawv yog; Staudenmaier, Hofmann, Brodie, thiab Hummers txoj kev. Cov txheej txheem no muaj ntau qhov sib txawv ntawm lawv.

- Nyob rau hauv kev tsim cov yeeb yaj kiab pob tshab hauv cov khoom siv hluav taws xob hloov tau yooj yim, lub hnub ci hlwb, tshuaj sensors, thiab lwm yam los ntawm kev siv graphene oxide ua ib zaj duab xis nyias tso rau hauv substrate.
- Rau kev hloov cov tin oxide hauv cov roj teeb thiab cov tshuaj kov.
- Raws li cov khoom siv hluav taws xob rau cov roj teeb, cov khoom siv hluav taws xob thiab lub hnub ci vim nws qhov chaw siab.
- txhawm rau txhim kho cov khoom ntawm cov khoom sib xyaw (lub zog tensile, elasticity, conductivity, thiab lwm yam) los ntawm kev sib xyaw nrog cov ntaub ntawv.
- Ntau daim ntawv thov kev kho mob vim yog cov khoom siv fluorescent.
Qhov txo qis Graphene Oxide yog dab tsi?
Txo graphene oxide yog txo daim ntawv ntawm monomolecular graphene oxide nplooj ntawv. Tsis muaj cov pab pawg ua haujlwm muaj pa oxygen vim cov pab pawg no raug txo los ntawm kev kho mob sib txawv. Tsis tas li ntawd, cov txheej txheem ntawm kev txo qis no yog cov txheej txheem tseem ceeb heev vim tias nws muaj kev cuam tshuam loj rau cov khoom kawg uas peb yuav tau txais. Vim tias, cov txheej txheem txiav txim siab ze npaum li cas yuav yog qhov zoo ntawm daim ntawv txo rau qhov zoo ntawm graphene zoo.
Rau cov ntawv thov xws li lub zog cia hauv qhov loj / kev lag luam-teev, txo graphene oxide yog qhov kev xaiv zoo. Nws yog qhov tseem ceeb vim tias, nws yooj yim heev los tsim cov khoom sib xyaw no hauv cov nplai loj dua li ua graphene.
Daim duab 02: Absorbance Spectroscopy thiab Raman Spectroscopy ntawm Graphite, Graphene Oxide thiab Txo Graphene Oxide
Muaj ntau txoj hauv kev uas peb tuaj yeem txo cov graphene oxide kom tau txais cov graphene oxide txo. Ntawm lawv, cov txheej txheem tseem ceeb yog thermal, tshuaj, lossis electrochemical txoj kev. Siv cov txheej txheem tshuaj muaj txiaj ntsig zoo vim tias, tom qab ntawd peb tuaj yeem ntsuas qhov ntau lawm raws li peb xav tau. Txawm li cas los xij, feem ntau, cov khoom siv los ntawm cov txheej txheem tshuaj muaj nws cov khoom siv hluav taws xob thiab thaj chaw saum npoo, hauv qab cov qauv.

Qhov txawv ntawm Graphene Oxide thiab Txo Graphene Oxide yog dab tsi?
Graphene oxide yog ib daim ntawv monomolecular ntawm graphite oxide thaum txo graphene oxide yog txo daim ntawv ntawm monomolecular graphene oxide nplooj ntawv. Li no, los ntawm qhov no, peb tuaj yeem nkag siab lub hauv paus ntawm qhov sib txawv ntawm graphene oxide thiab txo graphene oxide. Peb tuaj yeem siv graphene oxide los tsim graphene hauv me me thiab hauv txoj kev pheej yig, tab sis peb tuaj yeem siv cov ntawv txo qis ntawm graphene oxide los tsim graphene hauv kev lag luam loj.
Lwm qhov sib txawv ntawm graphene oxide thiab txo graphene oxide yog tias graphene oxide yog dispersible heev nyob rau hauv dej thiab lwm yam kuab tshuaj thaum txo daim ntawv yog tsawg dispersible; Nws yog dispersible ntawm tsawg concentrations. Qhov tseem ceeb tshaj plaws, qhov sib txawv tseem ceeb ntawm graphene oxide thiab txo qis graphene oxide yog tias graphene oxide muaj cov pa oxygen uas muaj cov pab pawg ua haujlwm thaum cov graphene oxide txo qis tsis muaj cov pa oxygen ua haujlwm. Nws yog vim peb tsim daim ntawv txo los ntawm kev txo qis ntawm graphene oxide.
Summary – Graphene Oxide vs Txo Graphene Oxide
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm graphene oxide thiab txo graphene oxide yog tias graphene oxide muaj cov pa oxygen uas muaj cov pab pawg ua haujlwm thaum cov graphene oxide txo qis tsis muaj cov pa oxygen ua haujlwm. Tsis tas li ntawd, peb tuaj yeem hloov graphite oxide rau hauv graphene oxide thiab tom qab ntawd mus rau hauv graphene oxide txo.
