Smart fibers with tunable luminescence properties, as a new form of visual output, present the potential to revolutionize personal living habits in future and are receiving more attention. However, huge challenge smart wearable materials is their stretching capability for seamless integration human body. Herein, stretchable thermochromic fluorescent prepared based on self-crystallinity phase change, using elastic polyurethane (PU) fiber matrix, meet dynamic requirements The switching fluorescence-emitting characteristic derived from reversible conversion dispersion/aggregation state fluorophore coumarin 6 (C6) quencher methylene blue (MB) phase-change material hexadecanoic acid (HcA) during heating/cooling processes. Considering important role materials, dye encapsuled solid via piercing–solidifying method avoid dissolution HcA by organic solvent PU spinning solution maintain excellent behavior fibers. obtained wet exhibit good emission contrast reversibility, well high elasticity 800% elongation. This work presents strategy constructing human–machine interaction communications.
