Fabrication method for graphene fiber using organic solvent as cogulant and graphene fiber fabricated by the same

摘要

Provided are a method for producing a graphene fiber using an organic solvent as a coagulant, and a graphene fiber prepared thereby. A dope solution was prepared in which GO sheets and MXene sheets were dispersed in a polar organic solvent. The dope solution is extruded into a coagulating solution having a higher absorption rate compared to the absorption rate of the polar organic solvent, and the polar organic solvent is diffused from the extruded dope solution into the coagulating solution to prepare a gel fiber. The gel fibers are dried and converted into MXene/GO hybrid fibers.
