Features

Thermochromic fibers are fibers whose color changes with temperature. Similarly, thermochromic fibers can be obtained by introducing thermochromic agents into fibers by filling and coating methods. Thermochromic polyvinylidene chloride (PVDC) fiber is a typical representative of this type of fibers.

Applications


  • In the commercial field, color-changing fibers are mostly used in sportswear such as mountaineering, skiing, swimming, skating, and life-saving clothing.

  • In the field of chemical research, photochromic fibers and thermochromic fibers still hold strong appeal. Introducing new photochromic substances or thermochromic substances into various fibers is one of the key research directions. Jimmy Nguyen et al. formulated liquid crystal (LC) into electrospun fibers to realize thermochromic fibers.

  • Experiments show that coaxial electrospinning with LC and solvent in the core can preserve the thermochromic properties of LC, resulting in thermochromic fibers. As shown, the LC in the core was observed to change from red to blue when the fiber was heated.
