Abstract: With the development of smart wearable devices and flexible electronics, electroluminescent devices, characterized by high brightness, low energy consumption, and fast response, have gradually become a research hotspot. Electroluminescent devices not only provide rich visual information and immersive experiences but also offer excellent comfort and portability. They exhibit broad application prospects, especially in various fields such as smart clothing, health monitoring, smart homes and display technology.
Fabric-based conductive composites, known for their lightweight, breathable, flexible and freely cuttable properties, offer significant design freedom and comfort for wearable devices. By integrating with various luminescent elements, these composites can provide stable electrical support for electroluminescent devices. Such materials can be obtained through methods such as coating, impregnation, in-situ polymerization, lamination, 3D printing, and electrospinning. Combining fabric-based conductive composites with electroluminescent devices through techniques such as scraping, spraying, hot pressing, and printing allows for the preparation of flexible, conductive, fabric-based electroluminescent devices that integrate the flexibility of fabrics with electroluminescent effects. These devices can conform to the contours of the human body, maintaining stable luminescent performance even under bending, stretching, deformation, and puncturing, and can withstand high temperatures, high humidity environments, and repeated washing. Therefore, they have broad applications in fields like fashion design, smart homes, health monitoring, and motion tracking. Despite some progress in the application of fabric-based conductive composites in electroluminescent devices, several challenges and issues remain. These primarily include poor material stability and durability, difficulties in combining rigid materials with textile materials, limited battery life, feasibility concerns for large-scale production, and cost control.
With the introduction of new materials and technologies, particularly the convergence of smart textiles with the Internet of Things, fabric-based conductive composites and electroluminescent devices are poised to embrace new opportunities for application. Driven by these opportunities, it is imperative to overcome the challenges of material stability and durability, and further optimize manufacturing costs and processes. Furthermore, environmental friendliness and recyclability will become important considerations. To address these challenges, it is necessary to systematically analyze the technical bottlenecks in the wearable industry, enhance material performance, and develop conductive composites with higher stability and durability. Meanwhile, by introducing automated and intelligent production equipment, production efficiency can be improved. Furthermore, optimizing the preparation process by simplifying it and selecting more economical materials while ensuring performance will be crucial. In the future, electroluminescent devices are poised to play a greater role in display technology, lighting, and wearable electronic devices.
