[Excerpt] Photonic crystals (PCs) are dielectric materials, capable of controlling the propagation of light
due to the photonic bandgap (PBG) and self-assemble in highly organized nano and
microstructures. PCs are found in nature and can be used for signaling, communication or
camouflage purposes. PCs structural coloration of textiles is ecological relevant due to the
inherent considerable reduction of water and chemical requirements. Furthermore, PCs can be
used to develop smart textiles able to change color through external stimuli such as: humidity,
light, pH, electrical and magnetic fields. This textiles can be applied in anti-counterfeiting
materials, wearable functional textiles, sensors, among others
