▎ 摘　　要

NOVELTY - The method involves preparing graphene oxide solution. The flake graphite is choose as the original material. The graphene oxide is prepared by Hummer's improved method. The graphene oxide solution is obtained. A transfer system is established. An easy-to-clean container is used as the transfer medium container. An easy-to-clean transfer platform is choose for carrying the carrier net. The transfer platform is immersed in the transfer medium. The carrying net is placed on the transfer platform for the transfer of graphene oxide. The graphene oxide solution prepared is dropped on the surface of the transfer medium described. The pump is used to remove the transfer medium. The graphene oxide layer is brought into contact with the carrier network. The carrier net that carries the graphene oxide sheet layer is obtained. The carrier mesh carrying the graphene oxide sheet is carried. The graphene oxide suitable for electron microscope imaging is obtained. USE - Preparation method of graphene oxide suitable for electron microscope imaging. ADVANTAGE - The method enables to prepare graphene oxide suitable for electron microscope imaging, which has high graphene coverage rate, controls the number of layers to ensure the yield, and improves the use performance of the graphene oxide, and avoids graphene oxide stacking wrinkle. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the graphene oxide transfer schematic diagram of the graphene oxide preparation method.
