“…The utilization of photonic crystal materials for textile coloration has received significant attention due to their ability to avoid wastewater generation and environmental pollution compared with traditional dyes or pigments. − Here, the BIOT process for fabricating structural colored textiles using the as-prepared FCIS particles was further investigated in this study. During the formation of structural color, the soft-segment P(BA-EA) in the shell would adhere to the fabrics in the process of BOIT to enhance the stability, and the fluorinated segment PFA would endow the obtained textile with a liquid-repellent property (Figure a).…”

Photonic crystal coatings with unique structural colors and self-cleaning properties have been providing an efficient way for substrate coloration. However, the enhancement of the robustness and durability of structural colored coatings to meet the requirements in diverse environments remains a challenging task. Here, to realize the application of photonic crystal films under various kinds of conditions, we present a poly(fluoroalkyl acrylate)-based colloidal photonic crystal (fCPC) coating. Fluorinated core−interlayer−shell (FCIS) colloidal particles of polystyrene (PS) core, poly(methyl methacrylate) (PMMA) interlayer, and poly(fluoroalkyl acrylate-ethyl acrylate-butyl acrylate) (P(FA-EA-BA)) shell copolymers have been first prepared by a stepwise emulsion polymerization. fCPCs with self-supporting property, reprocessing ability, friction resistance, as well as excellent wettability and liquid-repellent properties are successfully obtained via the bending-induced ordering technique (BIOT). When applied in antifouling applications, the fCPC film exhibits resistance against various oil and inorganic liquids. Furthermore, the fCPC coatings demonstrate their durability under outdoor conditions by maintaining stable color appearances during rainy and sunny conditions. Additionally, an electronic product adhered with the fCPC coatings is presented, which exhibits a surface that remains clean even after prolonged usage in comparison to the conventional CPC coating. Structural colored textiles with enhanced stability and functionalized liquid-repellent properties are achieved through a one-step process using FCIS particles. Therefore, the developed self-cleaning and comprehensive fCPC coatings capable of withstanding diverse conditions may open up new avenues for the advancement of structural coloration in decoration, vehicle, textile, and building.

“…11 To leverage the unique light-analyte interaction and result in measurable signals, 1D, 2D, and 3D photonic crystals have been extensively studied. [12][13][14] In 1D photonic crystals, the periodic structure enhances the light-analyte interaction by exploiting the unique properties of their layered architecture. 15 Besides, in 2D photonic crystals, the periodic nanostructures are arranged in a 2D lattice to provide even greater control over the propagation of light, allowing for precise tuning of resonance conditions.…”

“…Photonic crystals (PCs), composed of periodic micro- or nanostructures, have received widespread attention due to their remarkable physical properties and structural color and have numerous applications in fields such as display, printing, , sensing, − and dye, especially in the field of information encryption and anti-counterfeiting. − The current anti-counterfeiting applications associated with PCs can be roughly divided into two methods: The first one is regarded as responsive PCs with the single-mode only containing one or multiphotonic band gaps (PBGs) and exhibit vivid structural colors with invisible or switchable patterns, which are sensitive to the environment, including pH, temperature, solvent, , angle-changing, mechanical force, , and so on. The other encryption method using PCs involves integrating fluorescence and PBG into a dual-mode system.…”

Photonic crystals (PCs), composed of nanoparticles as building blocks, possess a unique photonic band gap (PBG). While incorporated with fluorescent materials such as quantum dots or dyes, the PCs could provide opportunities to expand their applications in anticounterfeiting and optical information security. Selecting suitable nanounits that can act as building blocks for constructing PCs and meanwhile serve as ideal carriers for fluorescent materials to maintain their intrinsic fluorescent properties has become a crucial challenge. In this study, carbon dots embedded ZIF-8 (ZIF-8/CDs) nanoparticles with different particle sizes were prepared, and ZIF-8/CDs-based PCs were successfully obtained via hand-writing and microfluidic technology. The CDs embedded in the ZIF-8 nanoparticles could effectively prevent the aggregation-caused quenching (ACQ) effect, resulting in enhanced fluorescence stability even in the solid form, which demonstrates that ZIF-8 could serve as ideal carriers for CDs. In this process, the monodispersity of the ZIF-8/CDs nanoparticles with a certain amount of CDs was maintained and could be used as building blocks for the construction of PCs. Consequently, dual-mode PCs exhibiting both PBGs and fluorescence characteristics were successfully obtained. Finally, ZIF-8/CDs-based PC beads with different structural colors and with/without CDs were employed as pixels to create an encrypted patterned array. The array can reveal an optical pattern via structural colors under visible light and a different pattern via fluorescence under UV light. The highly fluorescence-stable ZIF-8/CDs-based PCs explored in this study have paved the way for developing dual-mode optical encryption.
