Textile-based light-emitting devices are attracting more and more attention because of their potential applications in smart clothing, human-computer interfaces, safety warnings, entertainment fashion, etc. However, simple and efficient manufacturing of luminescent devices on fabrics even clothing with excellent stretchability and washability remains challenging. Here, a solvent-free thermal lamination process combined with laser engraving has been proposed to fabricate electroluminescent (EL) devices on textiles. All the preprepared components, such as the bottom electrode, the EL layer, and the top transparent electrode, were thermally laminated on the surface of textiles employing thermoplastic polyurethane (TPU) as the binding matrix. The stretchability, luminance, and interface adhesion of the EL devices were systematically studied, showing excellent mechanical durability at high temperature, in humid environments, withstanding repeated machine washing, and resistant to various forms of physical damage. As a demonstration of potential application, textile-based EL devices were fabricated, which could display colored and pixelated patterns as well as dynamic images. The thermal lamination technology developed in this work can potentially enable people to DIY (do it yourself) fabricate light-emitting devices on clothing using daily tools, which could facilitate the widespread use of textile-based wearable displays.
基于纺织品的发光器件因其在智能服装、人机界面、安全警示、娱乐时尚等方面的潜在应用而受到越来越多的关注。然而，在具有出色拉伸性和可洗性的织物甚至衣物上简单高效地制造发光器件仍然具有挑战性。在此，提出了一种无溶剂热层压工艺与激光雕刻相结合的方法，用于在纺织品上制造电致发光（EL）器件。所有预先制备的组件，如底部电极、EL层和顶部透明电极，都以热塑性聚氨酯（TPU）作为粘结基质热层压在纺织品表面。对EL器件的拉伸性、亮度和界面附着力进行了系统研究，结果表明其在高温、潮湿环境下具有出色的机械耐久性，能经受住反复的机洗，并且能抵抗各种形式的物理损伤。作为潜在应用的一个示范，制造了基于纺织品的EL器件，其能够显示彩色和像素化图案以及动态图像。这项工作中开发的热层压技术有可能使人们能够使用日常工具自己动手在衣物上制造发光器件，这将有助于基于纺织品的可穿戴显示器的广泛应用。
