The resulting SP-Br was applied to cotton fabric substrates through a simple screen-printing process, yielding a photochromic cotton fabric (SP-CF) with a functional coating capable of reversible color transitions.

After 10 color transition cycles, a slight reduction in the absorbance of the photochromic coated cotton fabric was observed; while its fatigue resistance remained virtually unaffected. Moreover, the screen-printed photochromic cotton fabric fabricated through this method exhibits several notable advantages, including rapid response time, excellent reversibility, significant color-changing ability, superior tunability in coloration, and reusability.
