The fabricated spider silk composite fibers retain the high mechanical strength (0.92 GPa) and unique reversible relaxation-contraction behavior of spider dragline silks. The aniline tetramer modified on the silk surface imparted electroactive properties to the composite fibers. The color of aniline tetramer/spider silk composite fibers could be controlled by applying different pH values and voltages. Furthermore, the composite fiber's resistivity could reach 186 Ω m which can conduct electrical current to light LEDs. This study could provide a valuable guideline for developing highly-conductive electrochromic spider silks for use in E-textiles.enPOLYANILINE; MECHANISM[SDGs]SDG3journal article10.1039/d2ra01065h360430652-s2.0-85137731731WOS:000839495500001https://api.elsevier.com/content/abstract/scopus_id/85137731731
