“…In particular, reversible thermochromic materials have the function of color memory [118]. It has the characteristics of discoloration at a specific temperature, showing a new color, and restoring to the original color when the temperature is restored to the initial temperature [119,120]. Therefore, reversible thermochromic materials can be used to prepare fibers with chromic properties.…”

The research and applications of fiber materials are directly related to the daily life of social populace and the development of relevant revolutionary manufacturing industry. However, the conventional fibers and fiber products can no longer meet the requirements of automation and intellectualization in modern society, as well as people's consumption needs in pursuit of smart, avant-grade, fashion and distinctiveness. The advanced fiber-shaped electronics with most desired designability and integration features have been explored and developed intensively during the last few years. The advanced fiber-based products such as wearable electronics and smart clothing can be employed as the second skin to enhance information exchange between humans and the external environment. In this review, the significant progress on flexible fiber-shaped multifunctional devices, including fiber-based energy harvesting devices, energy storage devices, chromatic devices, and actuators are discussed. Particularly, the fabrication procedures and application characteristics of multifunctional fiber devices such as fiber-shaped solar cells, lithium-ion batteries, actuators and electrochromic fibers are introduced in detail. Finally, we provide our perspectives on the challenges and future development of functional fiber-shaped devices.

“…To make fibers into fiber‐based electronic devices, the first and the most important aspect is the preparation of conductive fibers with considerable mechanical properties. A fiber can be made from any type of materials, including metals, alloys, ceramics, polymers, and their composites by different methods, e.g., melt‐spinning, wet‐spinning, electrospinning, scrolling, drawing, templated deposition, etc. Sometimes, surface treatment methods are accompanied .…”

Fiber is a symbol of human civilization, being ubiquitous but obscure in society over most of history. Fiber has been revived upon the advent of fiber‐based electronic devices in the past two decades. This is due to its desirable lightweight, flexible, and conformable characteristics, which enable it to play a fundamental role in the electronic and information era. Numerous fiber‐based electronic devices have sprung up in energy conversion, energy storage, sensing, actuation, etc. A possibility is thereby conceived that they can be integrated into smart systems compatible with the human body, consisting of biotic fiber‐based organs and tissues, which possess similar but more advanced functions. However, the design of mono‐/multifibers, the construction of fiber‐based devices, and the integration of these smart systems represent great challenges in fundamental understanding and practical implementation. A systematic review of the current state of the art with respect to the design and fabrication of electronic fiber materials, construction of fiber‐based devices, and integration of smart systems is presented. In addition, limitations of current fiber‐based devices and perspectives are explored toward potential and promising smart integration.

“…The efforts are to improve properties such as light fastness and to simplify application procedures. 2,[7][8][9][10] Nowadays is known reversible and irreversible thermochromism by single compound as well as by inorganic and organic composites. The reversible thermochromic organic pigment change color by applying heat and return back to original color after the system cools down.…”

“…Among the reversible pigments belongs also organic leuco dye system. 9 The leuco dye TPs consist of chromogenic compound or in other words color former (pH sensitive dye), developer (weak acid), and solvent (hydrophobic compound with long aliphatic chain accompanied by polar end group). 11,12 The leuco dye TPs are mostly colored in solid state and colorless above the melting temperature of solvent.…”

“…27 Reversible thermochromic fibers were prepared, where thermochromic microcapsules and polypropylene (PP) was used as color indicator and polymer fiber matrix, were obtained via melt spinning. 9 The color change as a function of temperature was studied on ternary thermochromic composites and the relation between color and structural changes in thermochromic systems comprising crystal violet lactone, bisfenol A, and tetradecanol was evaluated. 13,19 Also, the thermal properties of thermochromic (TC) composites based on dodecanol solvent were analyzed and the influence of dye and developer was analyzed in binary and ternary composites.…”

Dynamic color and phase change of chosen thermochromic systems were deeply investigated and their incorporation into polyurethane textile coating was developed. The colorimetric properties of three commercial reversible leuco dyes-based thermochromic pigments (TPs) with activation temperature at 38, 50, and 60 C were studied. Color change as a function of temperature was evaluated and colorimetric values were related to phase transition temperatures via differential scanning calorimetry (DSC) measurement. Light fastness of commercial TPs in polyurethane coating was determined by accelerated aging measurement and the color stability has been improved by using ultraviolet absorber (UVA). This research opens new possibilities for smart textiles, which is a very promising field in high-technology materials.
