NOVELTY - Reshaping a conductive network based on styrene-butadiene-styrene (SBS) conductive fibers, comprises (i) adding conductive materials into the ethyl acetate solution to prepare an ethyl acetate mixture, ultrasonicating for 0.8-1.5 hours, and magnetically stirring for 0.8-1.2 hours; where, the ethyl acetate mixture, the weight ratio of the conductive material is 59%; (ii) soaking the SBS conductive fiber in the ethyl acetate mixture, for 5-15 seconds, taking it out, and drying; where the conductive material is set in the same manner as the conductive material contained in the conductive layer of the SBS conductive fiber. USE - The method is useful for reshaping a conductive network based on SBS conductive fibers. ADVANTAGE - The method solves the technical problem of poor fiber electrical performance due to uneven distribution of conductive particles in the conductive fiber, makes the surface of the fiber smooth, and the electrical performance is effectively improved without reducing the fiber strength, is simple to operate, convenient and economical, does not cause damage to the fiber, enables the prepared fiber to have good spinnability, stretchability, good conductivity, high strain range and stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) conductive composite fiber, where the conductive composite fiber is first spun from a styrene butadiene styrene block copolymer solution as a core layer silk solution, styrene butadiene styrene block copolymer/graphene/carbon nanotube mixture as the skin spinning solution, through coaxial wet spinning to prepare the skin-core structure nascent fiber, and then the obtained nascent fiber is prepared after remodeling the conductive network; and (2) preparing conductive composite fibers by using a conductive network remodeling method based on SBS conductive fibers, comprising (i) preparing conductive composite fiber with sheath-core structure, (ii) mixing the graphene and carbon nanotubes, adding into solvent II to mix to form a graphene/carbon nanotube mixed solution, and then mixing the graphene/carbon nanotubes by batch ultrasound, ultrasonically treating, adding styrene butadiene styrene block copolymer into the graphene/carbon nanotube mixed solution, and magnetically stirring until it is fully dissolved to obtain a skin spinning solution, and (iii) carrying out coaxial wet spinning process of core layer spinning solution and the skin layer spinning solution to prepare a styrene butadiene styrene block with a skin-core structure copolymer/graphene/carbon nanotube nascent fibers, and remodeling of the internal conductive network of conductive composite fibers.
