a Fabrication process for the generation of CNT-embedded spandex fibers. b Raman spectra of CNT-coated fibers. c FE-SEM images of the fibers after successive coatings. CNTs are embedded within the spandex fiber comprising 56 strands. Scale bars: 300 μm (top) and 300 nm (bottom). d FE-SEM image of a single strand from the interior of the coated spandex fiber after 7 coatings. Scale bars: 30 μm (top) and 500 nm (bottom). e Change in conductivity and diameter of spandex fibers with successive coatings. f Stress–strain curve of the CNT-coated spandex fiber after 1, 3, 5, and 7 coatings. g Change in resistance of the fabricated fibers relative to the original value with strain.
