| titleOfInvention | Method for preparing high-strength conductive graphene fiber by large-size graphene oxide sheet |
| abstract | The invention discloses a method for preparing high-strength conductive graphene fiber by a large-size graphene oxide sheet. The method comprises the steps of: oxidizing expanded graphite and obtaining graphene oxide; dispersing the graphene oxide into water, carrying out centrifugal classification treatment on the dispersed graphene oxide, and obtaining the large-size even graphene oxide sheet; and finally, dispersing the graphene oxide into water or polar organic solvent, preparing spinning solution liquid crystal sol with the mass concentration of 1-20%, transferring the spinning solution liquid crystal sol into a spinning device, continuously squeezing spinning solution out from a spinning head capillary tube at the uniform velocity, leading the squeezed spinning solution into solidification liquid, drying the solidified primary fiber, obtaining graphene oxide fiber, and then obtaining the graphene fiber by chemical reduction. A spinning technology is simple; and the obtained graphene fiber is good in electrical conductivity, excellent in mechanical property and better in toughness, can be woven into pure-graphene fiber cloth, and also can be woven with other fibers in a blending way so as to make various functional fabrics, so that the high-strength conductive graphene fiber can be used for replacing carbon fiber in a plurality of fields. |
