Graphene material with fiber shape as well as preparation method and application thereof

The invention provides a graphene material with a fiber shape as well as a preparation method and an application thereof, and relates to the field of graphene. The graphene material provided by the invention has a crystal structure of graphene, and has the fiber shape; the graphene material has a diameter of 10 nm to 20 [mu]m; and the length of the graphene material is greater than or equal to 100[mu] m. According to the detection result of embodiments, the graphene material provided by the invention has the tissue morphology of fibers as well as the crystal structure of graphene, and can beused in the fields, such as the field of textile which is difficult for graphene powder materials and graphene single crystal materials to use. The graphene material with the fiber shape can be blended with various fibers, and various graphene composite fabrics are manufactured, so that the application range of the graphene material is greatly expanded. 本发明提供了一种具有纤维形状的石墨烯材料及其制备方法和应用，涉及石墨烯领域。本发明提供的石墨烯材料具有石墨烯的晶体结构，同时具有纤维的形状；
