▎ 摘  要

NOVELTY - Forming a graphene fiber involves reducing the graphene oxide fiber using a chemical reducing agent, preparing a hydrazine solution at 5-20 degrees C, reducing the griffin fibers by immersing them in the hydrazine solution, removing the griffin fibers from the hydrazine solution, washing them with a washing solution and drying the griffin fibers to obtain graphene fiber. USE - Method for forming a graphene fiber. ADVANTAGE - The method enables to obtain high-quality graphene fibers in a simple manner and minimizes harmful gasses generation during a reduction reaction at high temperatures. The product has excellent interfacial properties, improved electrical conductivity, improved adhesion with the carbon fiber, and improved mechanical strength.
