NOVELTY - Manufacturing graphene fiber involves selecting an appropriate amount of graphene oxide powder, and placing the selected graphene powder into a reactor filled with deionized water. The ultrasonic waves is used to oscillate and diffuse graphene, after the oscillation and diffusion of graphene is completed, the graphene oxide aqueous solution is obtained. The time for graphene to oscillate and diffuse is 50-60 minutes. The graphene oxide aqueous solution poured into the stirring box, started the stirring box, added chloroacetic acid solution to the stirring box during the stirring of graphene oxide, and heated the stirring box to 45-60 degrees C, it will be 60-80 minutes while stirring. The graphene oxide is stirred, cooled the graphene solution to room temperature, and used the filter membrane to filter the graphene solution. The graphene is dried when the graphene filtration is over, after the drying is completed, carboxylated graphene oxide is obtained. USE - Method for manufacturing graphene fiber. DETAILED DESCRIPTION - Manufacturing graphene fiber involves selecting an appropriate amount of graphene oxide powder, and placing the selected graphene powder into a reactor filled with deionized water. The ultrasonic waves is used to oscillate and diffuse graphene, after the oscillation and diffusion of graphene is completed, the graphene oxide aqueous solution is obtained. The time for graphene to oscillate and diffuse is 50-60 minutes. The graphene oxide aqueous solution poured into the stirring box, started the stirring box, added chloroacetic acid solution to the stirring box during the stirring of graphene oxide, and heated the stirring box to 45-60 degrees C, it will be 60-80 minutes while stirring. The graphene oxide is stirred, cooled the graphene solution to room temperature, and used the filter membrane to filter the graphene solution. The graphene is dried when the graphene filtration is over, after the drying is completed, carboxylated graphene oxide is obtained. The carboxylated graphene oxide injected into the reactor, placed N,N-dimethylformamide into the reactor to obtain spinning dope, and dispersed for 30-50 minutes to obtain spinning dope. The prepared spinning dope is injected into the wet spinning device for spinning. The wet spinning device includes a box. A liquid storage tank is fixedly connected to the inner wall of the box body. The upper surface of the liquid storage tank is fixedly connected with a liquid inlet pipe in the inner wall of the liquid storage tank. A control valve is installed in the lumen of the liquid inlet pipe. A shape plate is fixedly connected in the cavity of the liquid storage tank. The left inner wall of the shape plate is not fixedly connected with the bottom end surface of the liquid storage tank. A pressure plate is slidably connected to the cavity of the liquid storage tank in the liquid storage tank. The pressure plate is placed between the shape plate and the left inner wall of the liquid storage tank.
