Construction of Patterned CuO Photonic Crystals on Textile Substrates for Environmental Dyeing with Excellent Antibacterial Properties.

Structural dyeing has attracted much attention due to its advantages such as environmental friendliness, vivid color, and resistance to fading. Herein, we propose an alternative strategy for fabric coloring based on CuO microspheres. The strong Mie scattering effect of CuO microspheres enables the creation of vibrant structural colors on fabric surfaces.
