| titleOfInvention | A kind of large-scale preparation method of high-quality graphene |
| abstract | The present invention relates to a kind of large-scale preparation method of high-quality graphene, comprise the following steps：Aromatic hydrocarbons reagent is added into expanded graphite and obtains expanded graphite solution, oxidant is dissolved in organic solvent oxidizing agent solution is made, oxidizing agent solution is added in expanded graphite solution again, ultrasound makes it well mixed, after mixed solution reacts completely in the water bath of certain temperature, product is separated, that is, obtains graphene.Compared with prior art, the method that the present invention disassembles graphite using chemical oxidising polymerisation grafting, it is disassembled under the water bath condition no more than 100 DEG C to obtain graphene.This method economical and effective, simple to operate, the potentiality prepared with scale batch.Products therefrom quality better, defect is considerably less, there is good application prospect, is expected to be applied to the fields such as ultracapacitor, lithium ion battery, electronic device and ion-selective electrode. |
