Problems solved by technology

However, the above-mentioned various oxidation methods have problems such as cumbersome process and high energy consumption. For example, the production method of oxidation by oxidant needs to carry out neutralizing acid process, and it is necessary to remove harmful impurities such as non-carbon particles or catalytic metals in the carbon liquid. The requirements are too high, and improper control is prone to reunion, and it is difficult to guarantee product quality
The above-mentioned methods for producing and preparing graphene are extremely limited in popularization and application due to cumbersome processes, complicated equipment and difficult control.
