Progress in Research and Application of Luminescent Fibers
Luminescent fibers,innovative functionalized fibers made from fluorescent functional materials,have aroused considerable attention in smart textiles and biomedicine due to the inherent advantages of flexibility,wearability,implantability,and long-distance signal transmission.These fibers can be applied not only for pattern display and warning in textiles but also for visual transmission and flexible sensing displays.This article reviews the spinning methods,including wet spinning,electrospinning,and microfluidic spinning for fabricating luminescent fibers.The micro/nano-structures and optical properties of fluorescent fibers based on organic semiconductors and perovskite materials and their related applications in humidity sensing,display/warning systems,and biomedicine were emphasized.Finally,the challenges luminescent fibers face concerning organic molecular materials and preparation methods were summarized,and their future development trends are prospected.
