METHOD FOR MANUFACTURING HIGH-STRENGTH HIGH-CONDUCTIVITY FIBER AND HIGH-STRENGTH HIGH-CONDUCTIVITY FIBER MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing a high-strength high-conductivity fiber, and also relates to a high-strength high-conductivity fiber manufactured using the method. According to one embodiment of the present invention, the method for manufacturing a high-strength high-conductivity fiber comprises the steps of: preparing a spinning solution and a coagulation bath, which comprises a metal salt solution; forming a fiber, which comprises a metal ion, by spinning the spinning solution in the coagulation bath; stretching the coagulated fiber comprising a metal ion; drying the fiber comprising a metal ion; manufacturing a polymer/metal nanoparticle composite fiber by forming metal nanoparticles within the fiber by reducing the metal ion contained in the fiber; and drying or heat treating the fiber comprising metal nanoparticles.
