Schematic illustration of the aligned zinc oxide (ZnO) structural color fabrication process. a The electrospun nanofiber is collected in a vertical direction between parallel electrodes and transferred to the target substrate. b To remove the polymer component of the transferred nanofiber, heat treatment is performed at 500 °C to form a seed layer. c Patterning is performed using masking tape, and hydrothermal growth is performed in a constant temperature bath. d Removing the masking tape completes the final pattern. (Additional masking and hydrothermal growth allow complex patterns to be created)
