Abstract

Color-changeable fibers can provide diverse functions for intelligent wearable devices such as novel information displays and human-machine interfaces when woven into fabric. This work develops a low-cost, effective, and scalable strategy to produce thermochromic fibers by wet spinning. Through a combination of different thermochromic microcapsules, flexible fibers with abundant and reversible color changes are obtained. These color changes can be clearly observed by the naked eye. It is also found that the fibers exhibit excellent color-changing stability even after 8000 thermal cycles. Moreover, the thermochromic fibers can be fabricated on a large scale and easily woven or implanted into various fabrics with good mechanical performance. Driven by their good mechanical and physical characteristics, applications of thermochromic fibers in dynamic colored display are demonstrated. Dynamic quick response (QR) code display and recognition are successfully realized with thermochromic fabrics. This work well confirms the potential applications of thermochromic fibers in smart textiles, wearable devices, flexible displays, and human-machine interfaces.

柔性热致变色织物,可实现动态彩色显示。
变色纤维织成织物后,可为智能可穿戴设备提供新颖的信息显示、人机界面等多种功能。本研究开发了一种低成本、高效、可扩展的湿法纺丝生产热致变色纤维的方法。通过不同的热致变色微胶囊的组合,获得了色彩变化丰富且可逆的柔性纤维。这些颜色变化可以用肉眼清楚地观察到。实验还发现,即使在8000次热循环后,纤维仍表现出优异的变色稳定性。此外,热致变色纤维可以大规模制备,并且易于编织或植入各种织物中,具有良好的机械性能。热致变色纤维由于其良好的机械和物理特性,在动态彩色显示领域得到了广泛的应用。利用热致变色织物成功地实现了动态快速响应(QR)码的显示和识别。这项工作很好地证实了热致变色纤维在智能纺织品、可穿戴设备、柔性显示器和人机界面方面的潜在应用。

期刊介绍: Frontiers of Optoelectronics seeks to provide a multidisciplinary forum for a broad mix of peer-reviewed academic papers in order to promote rapid communication and exchange between researchers in China and abroad. It introduces and reflects significant achievements being made in the field of photonics or optoelectronics. The topics include, but are not limited to, semiconductor optoelectronics, nano-photonics, information photonics, energy photonics, ultrafast photonics, biomedical photonics, nonlinear photonics, fiber optics, laser and terahertz technology and intelligent photonics. The journal publishes reviews, research articles, letters, comments, special issues and so on. Frontiers of Optoelectronics especially encourages papers from new emerging and multidisciplinary areas, papers reflecting the international trends of research and development, and on special topics reporting progress made in the field of optoelectronics. All published papers will reflect the original thoughts of researchers and practitioners on basic theories, design and new technology in optoelectronics. Frontiers of Optoelectronics is strictly peer-reviewed and only accepts original submissions in English. It is a fully OA journal and the APCs are covered by Higher Education Press and Huazhong University of Science and Technology. ● Presents the latest developments in optoelectronics and optics ● Emphasizes the latest developments of new optoelectronic materials, devices, systems and applications ● Covers industrial photonics, information photonics, biomedical photonics, energy photonics, laser and terahertz technology, and more
