Abstract Structural colors widespread in nature have been theoretically in‐depth studied and manufactured through the artificial approaches such as self‐assembly nanolithography thanks to rapidly developing nanotechnology. based on elastomers hydrogels can be readily modulated upon mechanical stimuli, via adjusting structural parameters interplanar spacing diffractive angle. Recent breakthroughs mechanochromic structural‐colored materials has not only enriched their varieties but also...
Carbonized melamine foams are used for highly efficient solar steam generation, exhibiting ultrahigh evaporation rates and energy conversion efficiency.
Photonic crystals, which are materials with periodic dielectric constants on the submicroscale, have been focus of research for an extended period. soft extensively developed use as colorimetric indicators and mechanochromic sensors, but their limited mechanical properties molding characteristics only suitable films restrict practical implementation. Herein we report approach to synthesize highly stretchable photonic based a hydrogel system that is cross-linked by crystalline colloidal...
Graphitic carbon nitride (g‐C 3 N 4 ) has attracted tremendous attention in photocatalysis due to its extraordinary features, such as good thermal and chemical stability, metal‐free composition, easy preparation. However, the photocatalytic performance of g‐C is still restricted by limited surface area, inefficient visible light absorption, high recombination rate photoinduced charge carriers. Herein, a facile synthesis produce freestanding photonic crystals (PCs) crack‐free, highly ordered...

Abstract Resolution control and expansibility have always been challenges to the fabrication of structural color materials. Here, a facile strategy print cholesteric liquid crystal elastomers (CLCEs) into complex patterns with variable resolution enhanced is reported. A volatile solvent introduced synthesized CLC oligomers, modifying its rheological properties allowing direct‐ink‐writing (DIW) under mild conditions. The combination printing shear flow anisotropic deswelling ink drives...
The development of polymer-based persistent luminescence materials with color-tunable organic afterglow and multiple responses is highly desirable for applications in anti-counterfeiting, flexible displays, data-storage. However, achieving efficient from a single-phosphor system remains challenging task. Herein, by doping 9H-pyrido[3,4-b]indole (PI2) into an amorphous polyacrylamide matrix, hierarchical dual-mode emission developed, which exhibits due to excitation-, temperature-,...
Asymmetric optical transmission is fundamental and highly desirable in information processing full manipulation of lightwave. We here propose an asymmetric device consisting a gradient metasurface one-dimensional subwavelength grating. Owing to the unidirectional excitation surface plasmon polaritons (SPPs) by metasurface, SPP-assisted extraordinary transmission, forward incident light has much higher than backward one. combine temporal coupled mode theory finite-difference time-domain...
Chiral photonic films formed by cellulose nanocrystals co-assembled with self-healing hydrogels exhibit property, solvent sensitivity and CPL-dependent anti-counterfeiting.
Herein, a general strategy is proposed to boost the energy storage capability of pseudocapacitive materials (i.e., MnO2) their theoretical limits in unconventional 1D fiber configuration by rationally designing bicontinuous porous Ni skeleton@metal wire "sheath-core" metallic scaffold as versatile host. As proof concept, supported-MnO2 electrode demonstrated. The "sheath" design not only affords large surface area with ordered macropores for electrolyte-ion accessibility and high...
