| titleOfInvention | Method for preparing graphene from thermoplastic graphite material |
| abstract | The invention provides a method for preparing graphene from a thermoplastic graphite material, belonging to the field of graphene materials. According to the method, graphite is subjected to thermoplastic treatment, and a hydroxyl-terminated polymer is used for increasing the interlayer spacing of graphite and reducing the interlayer van der Waals force of the graphite, so that the graphite has thermoplastic flowability and flexibility when being processed in a screw extruder, the graphite is thinned through extending by virtue of the shearing stress generated by rotation of a screw, particularly the thinned graphite is sheared and directionally stripped by the screw under the strong shearing action of the screw after a polar high-molecular polymer and the hydroxyl-terminated polymer contained in the thermoplastic graphite are carbonized, and then, the graphene is obtained, so that a graphene layer structure is prevented from being damaged, the crystal lattice integrity of the graphene is better kept, and furthermore high-quality graphene with a large area is obtained. The method for preparing the graphene through carrying out thermoplastic treatment on the graphite and then stripping by using the screw extruder has wider industrial prospects and remarkable market application values and is suitable for large-scale production. |
