Hypothesis
Can stretchable thermochromic fluorescent fibers be created using self-crystallinity phase change to meet the dynamic requirements of the human body?
Conclusion
The study successfully developed stretchable thermochromic fluorescent fibers that exhibit good fluorescent emission contrast, reversibility, and high elasticity.
Supporting Evidence
- The fibers exhibited high elasticity of 800% elongation.
- The thermochromic fluorescent properties remained stable after 50 heating-cooling cycles.
- The encapsulation method used helped maintain the fluorescent properties of the dyes.
Takeaway
The researchers made stretchy fibers that change color when heated, which could be used in smart clothing to show information.
Methodology
The fibers were prepared using wet spinning technology with polyurethane as the matrix and thermochromic fluorescent capsules made via a piercing–solidifying method.
Limitations
The study does not specify the long-term durability of the fibers in various environmental conditions.
