Caffeic acid (CA), as a natural plant-derived polyphenol, has been widely used in surface coating technology in recent years due to its excellent properties. In this work, caffeic acid was introduced into the preparation of photonic band gap materials. By controlling the variables, a reasonable preparation method of polystyrene (PS) @polycaffeic (PCA)–Cu(II) core–shell microspheres was achieved: 1 mmol L−1 cupric chloride anhydrous (CuCl2), 3 mmol L−1 sodium perborate tetrahydrate (NaBO3·4H2O), 2 mmol L−1 CA and 2 g L−1 polystyrene (PS) were reacted at 50 °C for 10 min to prepare PS@PCA–Cu(II) core–shell microspheres through rapid oxidative polymerization of CA coated PS of different particle diameters. The amorphous photonic crystal structure was self-assembled through thermal assisted-gravity sedimentation, resulting in structural color nanomaterials with soft and uniform color, no angle dependence, stable mechanical fastness and excellent UV resistance.

The artificial design of nano-submicron structures to fabricate amorphous photonic crystals (APCs) is an effective means of obtaining non-iridescent structural color. APCs show great potential for applications in various fields, such as coating, textile coloring, displays, anti-counterfeiting, etc. However, a sharp fall in the structural color saturation can result due to incoherent scattering. In this paper, a type of light-absorbing material, SiO2@Ag, is prepared via a redox method. Non-iridescent structural color films with excellent color visibility and color saturation can be constructed through the layer-by-layer self-assembly of SiO2@Ag and SiO2 microspheres. Due to the inherent property of absorbing incoherent scattering light by the Ag nanoparticles, better structural color is generated without changing the originally ordered structure of the APC itself. Furthermore, no redshift or blueshift is caused by SiO2@Ag, which helps to maintain the color consistency well. Thus, excellent structure stability and color visibility are shown for the new type of APC film fabricated here, which will provide innovative ideas for the design and fabrication of non-iridescent structural color materials.

Amorphous photonic structures with non-iridescent and highly-stable structural color were fabricated via a simple one-step spray-coating technique. With this strategy, the obtained films on textile substrates presented short-ordered and amorphous photonic structures (APSs) similar to the amorphous nanostructures of avian feathers. The structural color presented the same hue when viewed at different angles and could be well controlled by varying the diameters of the SiO2nanospheres. The prepared fabrics with structural color exhibited high color stability due to stability in both the assembled physical structure and the refractive index. The high stability of the assembled physical structure was attributed to the cementing effect of Poly(methylmethacrylate-butylacrylate) P(MMA-BA) existing between textile substrate and SiO2nanospheres and among SiO2nanospheres, while the high stability in the refractive index was contributed by the liquid-resistance achieved by both the surface roughness and the low-surface-energy of the as-sprayed APSs. With the resistances to external forces and liquid invasion, the non-iridescent brilliant structural color of the as-prepared fabrics could be kept steady. In this study, an approach of fabricating APSs with non-iridescent and stable structural color was established to enhance its potential application in structural coloration of textiles, and other color-related smart textiles.Keywords:amorphous photonic structures;structural color;non-iridescent;color stability;textile substrates

Structural coloration of fabrics and phase-change thermoregulation are innovative development trends in the textile field. However, the inevitable assembly process of structural colors and the leakage of phase change materials make it extremely difficult. Herein, smart fabrics featuring non-iridescent structural color, and thermoregulation are developed by one-step loading of photonic nanopigments and phase change materials (PCMs). The photonic nanopigments are hollow silica (H-SiO 2 ) nanospheres with disordered metasurfaces that display non-iridescent structural colors without assembly. The used PCMs are lauric acid (LA) with solid-liquid phase change performance, which adsorb onto the surface of the H-SiO 2 nanospheres and form hydrogen bond cross-linkages with the oxyanions on the H-SiO 2 nanospheres surface. Among them, waterborne acrylic resin serves as an adhesive to immobilize the H-SiO 2 nanospheres and a cross-linker to form hydrogen bonds with molten LA, preventing its leakage. The resultant smart fabrics exhibit durable color stability and can withstand damage from diverse physical and chemical environments. The melting and crystallization enthalpy possessed are 38.94 and 40.51 J g⁻¹ respectively, endowing the smart fabrics with excellent thermoregulatory capabilities. This study offers a new paradigm for smart fabric advancement with structural color and thermoregulation.

Structural color films with high brightness, saturation and robust mechanical properties have been prepared by a two-step photopolymerization method using colloidal inks. The color saturation of the films could be controlled by the mass of the carbon black (CB) particles and polymerization time while the colors are closely related to the diameter of the CB@SiO 2 microspheres . The inks were prepared by dispersing CB@SiO 2 microspheres with black CB particles as the core and inorganic SiO 2 as the shell in poly(ethylene glycol diacrylate) (PEGDA) resins. The results of bending and rubbing tests showed that the addition of PEGDA prevented the formation of film cracks and enhanced mechanical properties without altering the original color. Structurally colored films were directly attached to a variety of substrates, including glass, metal, paper, and fabric. These colloidal inks have potential application in the fields of displays, paints, and other color-related fields.

Monodisperse colloidal particles have promising applications in electrophoretic displays with vivid colors, reversibility and low switching times. In this study, a facile, effective and large-scale strategy for preparing size-controlled Fe3O4@SiO2 particles is reported. Multiple Fe3O4 particles were synthesized by a modified solvothermal method using sodium citrate as a surface modifier with a binary solvent, and were then coated with a SiO2 layer to obtain a highly negatively charged surface via a modified Stöber method. Owing to the easily controlled sizes and sufficient surface charges, Fe3O4@SiO2 particles can be assembled into colloidal amorphous arrays with the balance of electrostatic repulsion and electrophoretic forces. The reflections cover wavelengths ranging from 802 to 453 nm, and were optimized by investigating the dependence of the particles on variables such as particle size, particle volume fraction, and electric field intensity. The large-scale preparation of electrically responsive Fe3O4@SiO2 particles facilitates an electrophoretic display with broad-range colors, showing the practical potential in industrial application.

Non-iridescent structural color films and pigments with novel enhanced microwave absorption characteristics are successfully fabricated at room temperature for the first time. The quasi-uniform magnetite nanoparticles (CV = 0.10 ∼ 0.20) with high refractive index (n = 2.42) and broad light absorption provide evident low-angle-independent property for the structural color pigments. More importantly, a universal technical protocol is developed for preparation of photonic crystals with inorganic nanoparticles, i.e., through designing of the binding strength between nanoparticles and mediated molecules, the slurry modulus is increased to 10 5 Pa, which effectively drives the nanoparticles to rapidly assemble into closely packed ordered arrays by our-designed powerful assembly technique. Additionally, the structural color materials are subjected as photonic crystal pigments (∼20 wt%) embedding in a transparent polymer matrix to form color coatings. Remarkably, the photonic crystal pigments exhibit strong magnetic coupling effect and enhanced microwave absorption performance due to the regular arrangement, with superior reflection loss (RL min ) values of −14.97 dB (increase by 65.8 % compared with randomized magnetic nanoparticles), and the effective absorption bandwidth (EAB) of 2.15 GHz. This new kind of photonic crystal pigment, combining visual color and radar wave absorption, provides a novel idea for developing of multi-wave-band high-performance stealth materials.

Background Photonic actuator materials that change their color in response to stimuli are uniquely suited for analyte sensing and visual detection. However, the changing iridescence produced by conventional photonic crystal structures in hydrogel materials can seriously confuse optical readouts, thus limiting their widespread application. Results Here, we report novel visual urea sensors with angle-independent structural colors. The urease-modified hydrogels were constructed into amorphous photonic structures. Based on the urease catalytic action induced charge variation within the hydrogel matrix, it leads to the volume change and corresponding diffraction wavelength shift of the photonic hydrogel biosensors, thereby enabling the stable and repeatable detection of urea. The response range of the sensors to urea solution ranged from 0 to 80 mM, with a linear range of 1–10 mM and a detection limit of 0.36 mM. Significance The visual and label-free sensors with non-iridescent structural colors have great potential in various response fields that require stable colors and open up a new avenue for the development of biomedical sensing photonic devices.

Noniridescent structural colors, by virtue of their pigment-like features and simple preparation techniques, have pivotal roles in color-related applications. However, because of the wide bandwidth resulting from coherent scattering, noniridescent structural colors lack the angle-altered color feature, which plays a critical role in angle-altered colored identification of structural color. Therefore, developing a novel strategy for noniridescent structural colors in security applications remains a challenge. Inspired by Diphylleia grayi, we developed a thickness-controlled silica@polydopamine (SiO2@PDA) amorphous arrays anticounterfeiting system. Owing to the melanin absorption of PDA, the SiO2@PDA amorphous arrays exhibit visual noniridescent structural colors in air but the brownish-black color of PDA in water. More importantly, when the arrays’ thickness exceeds 9 μm, the SiO2@PDA amorphous arrays display thickness-independent structural color in air but thickness-dependent PDA (brownish-black) color in water. On the basis of this finding, any designs of patterns with uniform or multicolored structural color can be encrypted by employing the distinct thicknesses and selectively disclosed in a liquid solvent environment. We believe these simple, user-interactive noniridescent structurally colored arrays are appealing for various security-related applications, such as anticounterfeiting.

Artificial structural colors based on short-range-ordered amorphous photonic structures (APSs) have attracted great scientific and industrial interest in recent years. However, the previously reported methods of self-assembling colloidal nanoparticles lack fine control of the APS coating and fixation on substrates and poorly realize three-dimensional (3D) conformal coatings for objects with irregular or highly curved surfaces. In this paper, atomization deposition of silica colloidal nanoparticles with poly(vinyl alcohol) as the additive is proposed to solve the above problems. By finely controlling the thicknesses of APS coatings, additive mixing of noniridescent structural colors is easily realized. Based on the intrinsic omnidirectional feature of atomization, a one-step 3D homogeneous conformal coating is also readily realized on various irregular or highly curved surfaces, including papers, resins, metal plates, ceramics, and flexible silk fabrics. The vivid coatings on silk fabrics by atomization deposition possess robust mechanical properties, which are confirmed by rubbing and laundering tests, showing great potential in developing an environmentally friendly coloring technique in the textile industry.

Solid silica or polystyrene spheres have been widely used to mimic solid melanin for fabricating amorphous photonic structures (APSs) and non-iridescent structural colors. However, few studies have been reported about mimicking APSs from hollow melanosomes in biology. A combination of HMSSs and carbon black (CB) is put forward to mimic hollow melanosomes for obtaining APSs and non-iridescent structural colors. Varied structural colors and reflection peaks of APSs are fabricated by adjusting diameters of HMSSs, amounts of CB and mixing ratios of different HMSSs. The stopband shift (137 nm) of the HMSS APSs infiltrated in ethanol is larger than the 40 nm red shift of solid silica photonic crystals (PCs) and the 105 nm red shift of HMSS PCs. The APSs from HMSSs show high sensitivity in visual detection for the chemicals with similar refractive indices , such as homologues and isomers. Based on structural difference of solid silica spheres and HMSSs, the combined APSs-LR could be obtained from the left side of solid silica spheres and the right side of HMSSs, the APSs-LU are from the lower layer of solid silica spheres and the upper layer of HMSSs. They could be used for information encryption and anti-counterfeiting by adjusting combination ways and the effective refractive indexes. The APSs show great potential applications in display, visual detection, information encryption and anti-counterfeiting.

Owing to the unique features of angle independence and wide-angle display, non-iridescent materials have attracted increasing interest in coating, decoration, and anti-counterfeiting. However, there are still some defects that limit their applications, such as relatively pale colors and suboptimal stability. Inspired by mussels' super-adhesivity and feathers' brightness, we present a graphene-doped non-iridescent pigment to overcome the aforementioned limitations. The elementary unit of the pigments is polydopamine-adhered multi-shell graphene oxide-encapsulated silica nanoparticles. These nanoparticles form into microspheres after simple spraying, and the obtained angle-independent patterns are imparted with higher color saturation and excellent self-adhesivity compared with traditional non-iridescent materials. Moreover, our pigments can also be employed as templates for negative replication, and the resultant inverse opal hydrogels are endowed with the same amorphous features and even some additional functions such as photothermal responsiveness and self-healing capacity. These features indicate promising prospects for our designed pigments.
