Abstract Combining responsive colloidal photonic crystals into invisible wettability patterns is important in steganography and watermarking for information encoding decoding. Using a bilayer crystal as regionally functionalized porous carrier, dual‐responsive surface with tunable wettability, reversible switching between wetting no wetting, responsivity to pressure solvents are reported. The mechanism of the design involves micropore shapes optical diffraction fabricated periodic...
Abstract Combining functional response materials into colloidal photonic crystals is an accepted encryption strategy for information security. Here, bilayer inverse heterostructure that enable instantaneously transparentizing of the top layer and simultaneously releasing reflected light bottom when exposed to ethanol are reported. The transition can quickly return its original state after evaporation ethanol. In addition, film responsive water, which shows redshift bandgap position....
Radiative cooling shows great promise in eco-friendly space due to its zero-energy consumption. For subambient hot humid subtropical/tropical climates, achieving ultrahigh solar reflectance (≥96%), durable ultraviolet (UV) resistance, and surface superhydrophobicity simultaneously is critical, which, however, challenging for most state-of-the-art scalable polymer-based coolers. Here an organic-inorganic tandem structure reported address this challenge, which comprises a bottom...
Due to the large specific surface area and continuous pores in structures, metal–organic frameworks (MOFs) show great advantages adsorption of volatile organic compounds (VOCs). Photonic crystal (PC) sensors derived from MOFs are promising for visual detection VOC gases. However, they still have problems low sensitivity poor color saturation tunability. Here, inspired by vapor-sensitive scales Tmesisternus isabellae beetle scattering light absorption polydopamine, a porous one-dimensional PC...
Flocculants are crucial agents in wastewater treatment because they can remove oppositely charged impurities effectively and swiftly. However, flocculation also inevitably causes secondary contamination due to the residual properties, nonreusability, nondegradability of traditional flocculant molecules. Herein, an ecofriendly starch-based flocculant, i.e., 2,4-bis(dimethylamino)-[1,3,5]-triazine-6-starch, was synthesized via a preactivation-etherification strategy. The large molecular weight...
Colorimetric sensors, as a key branch of the application photonic crystals (PCs), brings enthusiasm to scientists do research.

Abstract Li–S batteries are one of the most promising candidates for next generation because their high theoretical specific capacity 1675 mA h g −1 . However, dissolution polysulfide causes severe fading during cycling. Herein, a 3 D CoO/Co‐activated free‐standing porous carbon fiber cloth (CoO/Co@PCF) is designed to suppress diffusion from cathode. The metallic Co and polar CoO can anchor through Co−S ionic bonding pores provide abundant active sites electrochemical reactions....
Photonic elastomers, capable of converting imperceptible deformations into visible colors, show significant potential in smart materials.

Compared with traditional paper, water rewritable photonic crystal (PC) paper is an environmentally friendly and low resource-consuming material for information storage. Although, recently reported PC papers have high-quality structure color showing promising prospect, the size, that within several centimeters, still limits turning it from potential to reality. Here, we present a new film as large A4 size (210 × 300 mm2) color. The prepared by thermal assisted self-assembly on air-liquid...
Although the forward diffraction of three-dimensional (3D) photonic crystal is easily applied to a photoswitch, backward rainbows are rarely reported. The first rotational photoswitch based on bilayer 3D with diffractions similar those two-dimensional crystals was fabricated by vertically combining different thicknesses nanoparticle templates. When rotating crystal, opening or closing shows periodic reproducibility values 30 and 60°. Different periods regulated thickness scattering effect...
