The application discloses a modification method for realizing the conductivity of basalt fiber. The method forms a conductive polymer on the surface of the basalt fiber through an in-situ polymerization method, so that the basalt fiber is endowed with conductivity. The method can control the particle size of the conductive polymer, the coating thickness and the conductivity of the basalt fiber by adjusting experimental parameters such as the types and concentrations of monomers, oxidants and dopants and the polymerization reaction time. The method is simple and efficient in manufacturing process, and is strong in controllability of structure and performance. The modified basalt fiber has good conductivity, and the resistivity of the basalt fiber is adjustable in the range of 1~10 ‑3 Ω·cm, which widens the application of the basalt fiber in the fields of electromagnetic shielding and electrostatic protection. Moreover, the method does not damage the structure of the fiber itself while realizing the conductivity of the basalt fiber, and improves the mechanical performance of the basalt fiber to a certain extent.
