Stretchable multi-luminescent fibers with AIEgens


Luminescent fibers are increasingly demanded due to their promising applications in smart textiles for fashion designs and a variety of functionalities. Herein, we report a highly stretchable, lightweight, multicolor light-emitting fiber enabled by luminogens with aggregation-induced emission characteristic (AIEgens). A one-step extrusion and transient thermal curing method is developed for scalable and continuous dry-wet spinning of the luminescent polydimethylsiloxane (PDMS) fibers. The resulting fibers emit intense lights (red, green, and blue, respectively) under excitation of ultraviolet light even when the content of fluorophore is as low as 0.3 wt%. The fibers exhibit excellent mechanical properties, which allow knitting or weaving them into demonstrated functional fabrics for displays, aesthetic designs, and anti-counterfeiting. Comparing with many reported light-emitting fibers that require electric power sources or complicated fabrication protocols but degraded flexibility, our approach to luminescent fibers/fabrics show great potentials for wearable smart textiles.
