| titleOfInvention | The preparation method of single-layer graphene dispersion liquid |
| abstract | The present invention provides a kind of preparation methods of single-layer graphene dispersion liquid, comprising the following steps: provides natural flake graphite, carries out oxidation processes, prepare graphite oxide slurry；Deionized water is added in graphite oxide slurry, is removed by high-pressure homogeneous crusher machine, until obtaining the graphene oxide that average thickness is 0.4-0.7nm, average piece diameter is 0.8-10 μm；After graphene oxide is freeze-dried, it is passed through nitrogen and hydrogen mixture and carries out temperature programming processing, be cooled to room temperature, obtain single-layer graphene powder；Single-layer graphene powder is placed in spray mixer, to contain the ethanol solution of dispersing agent as spray, it is spray-dried under conditions of revolving speed is 300-1000rpm, temperature is 70-100 DEG C, after to be spray dried, continues to stir to get modified single-layer graphene powder；Modified single-layer graphene powder is dissolved in organic solvent for ultrasonic dispersion processing, obtains single-layer graphene dispersion liquid. |
