| titleOfInvention | A kind of preparation method of graphene oxide |
| abstract | The invention belongs to technical field of graphene preparation, in particular to a kind of preparation method of graphene oxide.It the described method comprises the following steps: (1) using common graphite powder as raw material, the graphite suspension containing thin graphite flake layer is made using liquid phase stripping method；(2) it filters and dry, obtains graphite flake powder；(3) oxidant is added, carries out oxidation reaction；(4) graphite oxide is formed at 20-40 DEG C by aoxidizing bold and vigorous ice method；(5) graphite oxide is cleaned and is dried；Then deionized water or organic solvent is added, and is ultrasonically treated, the graphene oxide dispersion containing graphene oxide is obtained.The present invention is reoxidized using ultrasonic oscillation removing graphite and prepares graphene oxide, and obtained graphene oxide can be dispersed in water, acid solution, alkaline solution or organic solution, form evenly dispersed graphene oxide.This method has many advantages, such as that simple process, success rate are high, operating condition is easily controllable. |
