How can fabric mimic the iridescence of natural elements like fish scales or beetles?
The mesmerizing iridescence seen in fish scales and beetle shells is a result of structural color, where microscopic layers reflect and refract light to create shifting hues. Modern textiles replicate this effect through innovative techniques like multi-layer thin films, diffraction gratings, or photonic crystals embedded in fibers. By mimicking nature's nanostructures, fabrics can achieve dynamic color shifts without dyes, offering sustainable and eye-catching alternatives for fashion and design. Advanced materials like holographic films or coated polymers further enhance this effect, blending science and artistry to bring nature's brilliance to textiles.
