Fiber is a new form of macroscopic graphene nanomaterials besides powder, film and aerogel.Graphene fibers are much more advantageous in terms of mechanical strength, electrical conductivity, and physical flexibility.Just like traditional carbon fibers, they can be easily processed into yarns, fabrics, and even 3-dimentional scaffolds by twisting, weaving and knitting.And similar with carbon nanotube (CNT) fibers,they are very promising in the fields of sensors,actuators, and wearable energy devices due to their superior performance and lower cost.Several methods have been developed to prepare graphene fibers, including drawing assembly of graphene films, hydrothermal pipeline-confined assembly of graphene oxide (GO), and wet-spinning of liquid crystals (LCs) of GO followed by reduction.[1-3] However, those fibers show poor electrochemical performance in supercapacitors due to serious stacking of RGO sheets.
