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.

还原的氧化石墨烯官能化的可拉伸多色电热彩色纤维

基于可还原的氧化石墨烯（RGO）功能化的弹性导电纤维和各种热致变色材料，制备了可拉伸的多色电热彩色纤维。由于导电纤维具有良好的电阻加热性能，因此可以在15s内切换纤维的颜色。通过组合使用不同的热致变色材料，可以用肉眼清楚地观察到丰富且可逆的颜色变化（例如，分别从橙色，红色，绿色到黄色，紫色，蓝色和白色）。此外，由于多层纤维的结构稳定性和RGO的优异的电热稳定性，即使在1000次电阻加热或拉伸/释放循环之后，该纤维也表现出优异的变色稳定性。最后，它们很容易编织成纺织品并编成彩色手链，这显示出巨大的应用价值，尤其是对于可拉伸的视觉传感器和与服装集成在一起的可穿戴显示器。
