Multiple Colors Output on Voile through 3D Colloidal Crystals with Robust Mechanical Properties
“Fast fashion” might be cheap, but its high environmental cost from dyes polluting the water near factories has been well documented. To help stem the tide of dyes from entering streams and rivers, scientists report in the journal ACS Applied Materials & Interfaces a nonpolluting method to color textiles using 3D colloidal crystals.
Dyes and pigments are chemical colors that produce their visual effect by selectively absorbing and reflecting specific wavelengths of visible light. Structural or physical colors – such as those of opals, peacock feathers and butterfly wings – result from light-modifying micro- and nanostructures...
