Area of Science:

  • Materials Science
  • Nanotechnology
  • Textile Engineering

Background:

  • Photonic fibers are key for structurally colored fabrics.
  • Mechanochromic fibers offer dynamic color-tunability, inspired by natural phenomena like chameleon skins.

Purpose of the Study:

  • To develop a controlled, continuous method for producing mechanochromic photonic fibers.
  • To explore the relationship between fiber structure, mechanical deformation, and resulting color changes.

Main Methods:

  • Utilized microfluidic jetting with flow-focusing of photocurable silica particle dispersions.
  • In situ photocuring of the fiber jet using ultraviolet irradiation.
  • Investigated color changes induced by elastic stretching and relaxation of the fibers.

Main Results:

  • Successfully produced continuous mechanochromic photonic fibers with tunable structural colors.
  • Demonstrated dynamic, reversible color shifts (blue shift) upon elastic fiber stretching.
  • Achieved a wide color tuning range and high reversibility due to the nonclose-packed silica particle array.

Conclusions:

  • Microfluidic jetting is an effective technique for fabricating advanced mechanochromic photonic fibers.
  • The elastic and structural properties of the fibers allow for dynamic and reversible color changes.
  • Potential for creating novel color-changing textiles and functional materials.
