Self-coloring of polymeric materials without coating/painting

Structural coloration is a natural consequence of interactions between microscopically structured surface and visible light. The objective of this experiment is to achieve submicron wavelength of 0.5-1 µm atop polymer. By obtaining the submicron wavelength, structural coloration would be visible. Th...
