▎ 摘　　要

NOVELTY - Method for preparing partially wrinkled graphite, involves (a) ultrasonically mixing graphene oxide and solvent uniformly to obtain a graphene oxide solution, (b) atomizing solution with ultrasonic to obtain graphene oxide micro liquid droplets, (c) driving micro-droplets into pulse laser beam by high-speed airflow, when laser is at low-level, pulse laser beams do not discharge light, graphene oxide droplets enter lower portion of laser beam under driving of the high speed airflow, (d) irradiating micro droplets of graphene oxide under light of a laser beam, and reacting laser with laser, (e) converging the light emitted from the laser head on the local area of droplet tail, where collected laser beam has a bent gas-liquid interface, (f) collecting and removing liquid solvent from the drop-down graphene oxide microporous droplets irradiated by laser, and collecting and removing liquid solvent in graphene oxide micro-droplet airflow irradiated by laser through suction filtration. USE - Preparation method of partially wrinkled oxidation graphite used in thin film technology and coating technology. Can also be used in atomic force microscope (AFM). ADVANTAGE - The method prepares partially pleated graphene oxide with sheet layer, wrinkle-shaped part of the wrinkle graphene oxide particles, keeping conformal capability of the two-dimensional sheet shape, and has application value of three-dimensional pleat shape. The process is simple, the preparation is fast, and there is no toxic and harmful substance discharge. The method uses intermittent light characteristics of the high speed gas and the pulse laser, the micro liquid drop into the laser beam, through the laser beams with high energy density to irradiate the graphene oxide micro liquid droplets, using the reaction between the laser and the micro-droplets and the ionization generated locally. DESCRIPTION OF DRAWING(S) - The drawing shows a profile view of a partially pleated oxidised graphite
