Abstract

The invention relates to stretchable electric-heating-induced chameleon fiber. Core-spun yarn serves as an elastic substrate, and a conducting layer, a protection layer and a chameleon layer are prepared on the surface of the substrate in sequence. A preparing method comprises the steps of pre-treatment of the core-covering yarn, synthesis of the core-spun yarn modified by multilayer graphene oxide, synthesis of the core-spun yarn modified by multilayer graphene, and synthesis of stretchable electric-heating-induced chameleon fiber. According to the stretchable electric-heating-induced chameleon fiber and the preparing method thereof, the method is simple, the condition is mild, the cost is low, and thus the stretchable electric-heating-induced chameleon fiber is suitable for scale production. The obtained stretchable electric-heating-induced chameleon fiber can be changed into multiple colors, has good electroconductivity and cycling stability, and meanwhile shows excellent stretchable performance; basis is provided for functionalization and intellectualization of fiber, and the stretchable electric-heating-induced chameleon fiber has high application value in the aspect like military camouflage, intelligent wearability and visual sensors.

Description

technical field [0001] The invention belongs to the field of color-changing fibers, and in particular relates to a stretchable electrothermochromic fiber and a preparation method thereof. Background technique [0002] Color-changing fiber is a fiber with special composition or structure that can change color after being stimulated by external conditions such as light, electricity, magnetism, heat, moisture or radiation. The color-changing fiber was first used on the battlefield of the Vietnam War in 1970. The Cyanamide company of the United States developed a photochromic fiber to meet the requirements of the US military for combat clothing. This type of fiber can change color after absorbing light. Since then, color-changing fibers with different mechanisms have continued to develop, mainly including thermochromism, electrochromism, magnetochromism, photochromism, wet-induced coloring, etc., showing great potential in smart wearables, military camouflage, and flexible displ...
