NOVELTY - Preparation of graphene nanomaterial composite having axial carbon fiber involves taking cellulose and urea, melamine or ammonium thiocyanate as raw material, where the mass ratio of the cellulose and urea, melamine or ammonium thiocyanate is 100: 1 to 1: 1000, mixing, placing under the protection of nitrogen for calcining at 700-1200 degrees C, and finally cooling to obtain graphene nanomaterial composite having axial carbon fiber. USE - For preparation of graphene nanomaterial composite having axial carbon fiber (claimed), which is used for catalysis, energy storage, photo-electric device and sensor fields. ADVANTAGE - Compared with the prior art, the process is simple, safe and low-cost, can achieve large-scale continuous production of graphene nanomaterial composite. The products obtained have broad application prospects in catalysis, energy storage, in many areas, such as optoelectronic devices and sensors.
