The invention discloses a method for preparing black phosphorus fiber by utilizing electrostatic spinning, which comprises the following steps: dispersing blocky or powdery black phosphorus in a mixed solvent of polyacrylonitrile and N, N-dimethylformamide, adding an organic solvent as a protective agent in the preparation process to prepare a spinning solution with the mass concentration of 1-20%, transferring the spinning solution into a spinning device, and performing electrostatic spinning to obtain the black phosphorus fiber. And drying to obtain the black phosphorus fiber. The black phosphorus fiber obtained by the method is finer in diameter and higher in yield. The spinning process is simple, can be operated at room temperature, does not use a strong corrosion reagent, and is green and environment-friendly in process. The prepared black phosphorus fiber has the characteristics of high rigidity, good toughness, excellent conductivity and the like, can be blended with other fibers to form various fabric
