Abstract

Abstract : Stretchable and multicolor electrothermal chromatic fibers are prepared with a multilayered structure and achieve satisfactory comprehensive properties. Abstract : A stretchable and multicolor electrothermal chromatic fiber is prepared based on reduced graphene oxide (RGO) functionalized elastic conductive fibers and various thermochromic materials. The colors of the fibers can be switched within 15s due to the good resistive-heating performance of the conductive fibers. Through a combination of different thermochromic materials, abundant and reversible color changes are clearly observed by the naked eye ( e.g., from orange, red, green to yellow, purple, blue and white, respectively). Moreover, the fibers exhibit excellent color changing stability even after 1000 resistive-heating or stretching/releasing cycles owing to the structural stability of the multilayered fibers and the excellent electrothermal stability of RGO. Finally, they are easily woven into textiles and plaited into colorful hand chains, which showed huge application value especially for stretchable visual sensors and clothing integrated wearable displays.
