▎ 摘 要
NOVELTY - Manufacture of graphene oxide fiber or graphene fiber involves preparing a spinning liquid by dispersing graphene or its oxide in a solvent, wet spinning in a coagulation bath in a state in which electric field is applied in discharge direction of the spinning liquid, so as to produce a gel fiber, and drying the gel fiber. USE - Manufacture of graphene oxide fiber or graphene fiber. Uses include but are not limited to electrode of supercapacitor and secondary battery, sensor, actuator, touchpanel, flexible display, solar cell, heat-radiation film, coating material, tide-desalinization filter, super-high-speed battery charger, etc. ADVANTAGE - The method is capable of producing graphene oxide fiber or graphene fiber having excellent mechanical properties, with high degree of orientation by simple process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining wet spinning process.
