Photonic crystals, including amorphous and ordered photonic crystals (APCs and OPCs), show wide applications in color displays, sensors, and pigments. The fabrication of APCs and OPCs by one method is highly desired; however, it remains a big challenge due to the lack of fine control of the assembly behavior of the colloids. Herein, an efficient surface-charge-assisted colloidal assembly (SCACA) has been developed to fabricate APCs with noniridescent structural colors and OPCs with iridescent colors by the coassembly of aminated silica particles and nanosized carbon black (CB) in solution with different pH values. The surface charge of the particle is demonstrated to be the key factor manipulating the assembly behavior of the particles; thus, the structure, defect, reflection intensity, and angle-in/dependent structural color of the photonic crystals can be precisely controlled. Compared with previous strategies, SCACA is considerably simple and efficient in preparing APCs and OPCs, which makes the fabrication more controllable, convenient, and scalable. Moreover, by combining the noniridescent and iridescent structural colors of APCs and OPCs, a single color- and multicolor-based coding–decoding system has been developed, in which the structural colors, numbers, positions, and angle in/dependency of codes can be hidden and recognized by naked eyes at varied viewing angles. This work provides a new insight for precisely manipulating the assembly of the colloids into APCs and OPCs and extends their combined applications in anticounterfeiting and information storage.

Developing multifunctional structural color hydrogel skin without sacrificing the unique periodic structure of photonic crystals is still a challenge due to the photonic bandgap limitation. Taking advantage of the synergistic effect of electrostatic repulsion and electronic conductivity, an intelligent structural color hydrogel skin with electrical and photonic sensing capabilities has been developed by doping MXene (Ti3C2Tx) nanosheets and adhesive functional groups (nucleobases) into colloidal particle solutions. The introduction of MXene nanosheets could improve both the stability and electrical conductivity of the colloidal particle solutions, resulting in a conductive hydrogel with bright structural colors. With the help of functional groups of nucleobases, the resulting structural color hydrogel was also endowed with high biocompatibility and strong adhesion to different substrates, including the wet surfaces of tissues. It was demonstrated that the structural color hydrogel can not only realize visual sensing of tiny limb movements but also provide stable electrical sensing signals. The intelligent structural color hydrogel can be integrated into a capacitor device as a hydrogel electronic skin to simulate the sensory function of human skin. The results showed that such hydrogel skin can simulate the touch of human skin and perceive tiny movements on the body surface with both electrical and photonic signals. These features of the multifunctional structural color hydrogels make them potentially excellent value in bioinspired hydrogel skin electronics.

Patterning colloidal photonic crystals have broad important applications in optical devices, functional coatings, full color displays, and colorimetric sensors. In this paper, a clickable colloidal photonic crystal using vinyl-modified sub-micrometer silica particles as building blocks was proposed to pattern photonic crystals. By click chemistry, different chemical groups were simply grafted to the clickable photonic crystals film and obtained wettability-encoded structure color patterns. The clickable photonic crystals provide a simple, controllable, and rapid path to pattern photonic crystals.

Robust, washable, steam permeable fabrics that display solvatochromic structural color changes are fabricated by a solvent evaporation-driven self-assembly method using poly(styrene–butyl acrylate–acrylic acid) core–shell colloidal microspheres. The colloidal microspheres self-assemble into a periodic arrangement to form a colorless transparent film on fabrics. Because of the lack of refractive index difference between the film and fabric, the fabric retains its original color (black polyester in this work). As soon as the fabric is wetted, its color changes. When the wetted fabric is completely dried, its original black color appears again. These solvatochromic fabrics do not show apparent color fading during repeated stretching or after laundering. The structural color fabrics show promising steam permeability with only a 13% decrease compared with the original fabrics. Therefore, the wearability of the fabric meets the demands for applications in the textile industry.

The detection of p-nitrophenol (PNP) is of great significance for assessment of environment pollution and potential health risks. In this study, based on inverse opal polymeric photonic crystals (IOPPCs), a selective and visual sensor for high-performance PNP detection is developed. Due to their unique optical properties, IOPPCs report events by change of color, which can easily be observed by the naked eye. Hydroxyethyl methacrylate (HEMA) was selected as the functional monomer with which to fabricate the IOPPCs. By precisely adjusting the molar ratio between the functional monomer and the crosslinker, the sensors were only able to be sensitive to a specific solution, thus realizing the visual, selective, and semi-quantitative detection of PNP. When the sensors were immersed in different concentrations of PNP solution, their Bragg diffraction wavelengths showed different redshifts. The color of the IOPPCs changed from green to red as the peak shift of Bragg diffraction occurred. In addition, the IOPPCs displayed good interference immunity and reusability.Keywords:polymeric photonic crystals;structural color;p-nitrophenol

A new type of photonic crystal structural colored fiber was prepared by assembling superparamagnetic chains on the surface of a flexible fiber in a magnetic field under photopolymerization . In this system, fixed structural colors (blue, green, and red) were generated instantaneously. The fiber with multi-stopband can also be prepared by carefully controlling the size of the magnetic spheres in each photopolymerization procedure. This method would be fast and facile for the further study of structural color on the surface of the fiber, and the process may be used to simulate the conventional fiber coloration process.

Structural color materials have been studied for decades because of their fascinating properties. Effects in this area are the trend to develop functional structural color materials with new components, structures, or morphologies for different applications. In this study, we found that the coassembled graphene oxide (GO) and colloid nanoparticles in droplets could form component phase separations, and thus, previously unknown anisotropic structural color particles (SCPs) with hemispherical colloidal crystal cluster and oblate GO component could be achieved. The anisotropic SCPs, as well as their inverse opal hydrogel derivatives, were endowed with brilliant structural colors and controllable capabilities of fixation, location, orientation, and even responsiveness due to their specific structure, morphology, and components. We have also demonstrated that the anisotropic hydrogel SCPs with these features were ideal candidates for dynamic cell monitoring and sensing. These properties indicate that the anisotropic SCPs and their derivatives have huge potential values in biomedical areas.

An electrically tunable photonic crystal is developed utilizing crystalline colloidal arrays of particles with low density and high optical contrast. Through modulation of the charge on the surface of particle, and the applied electric field, the peak position of the reflection changes with the increasing voltage. The possibility of using phenolic resin to realize the full color modulation was obtained, which paves a way to develop a novel reflective display with organic nanospheres.

Formaldehyde and other harmful gases cause environmental pollution and threaten human health. Environment-friendly coatings is an effective strategy to address these environmental and health concerns. In this study, a large-scale amorphous photonic crystals (APC) based on modified ZIF-8 (H xh -ZIF-8) with photocatalytic degradation of formaldehyde and tunable structural color were designed for eco-friendly coatings by programmable smart manufacturing. As APC unit, H xh -ZIF-8 nanoparticles with controllable diameters were synthesized utilizing solvothermal method and the −N = C = O group was introduced with thermal oxidation. The results of photocatalytic degradation revealed that H 5h -ZIF-8, through thermal oxidation, exhibited a formaldehyde degradation rate 9.8 times than that of ZIF-8. The main reactive components in photocatalysis were holes (h + ) and superoxide radicals ( · O 2 – ), showcasing both stability and reproducibility. The color and brightness of the APC were adjusted by tuning the H xh -ZIF-8 diameter. The angle-independent APC ranging from red to purple were fabricated with 177, 165 and 235 nm H xh -ZIF-8 nanoparticles in various proportions with programmable smart manufacturing. In this study, a large-scale ZIF-8-based APC was designed with programmable smart manufacturing for environment-friendly coating, which combined environmental protection technology with structural color, and paved a new strategy for the development of multifunctional materials in air quality management.

Structural coloration holds significant promise for achieving ecological coloring of textiles. Caffeic acid, a natural plant polyphenol characterized by its cost-effectiveness, environmental friendliness, and non-toxic properties, has been identified as a key player in this context. It is found that caffeic acid can generate a polycaffeic acid (PCfA) nanofilm at the gas-liquid interface under certain conditions. In this work, caffeic acid was utilized to create thin film nanostructures by self-polymerization for the structural coloration of cotton fabrics, where the hue of the structural colors can be adjusted by polymerization time. Additionally, the incorporation of polyvinyl alcohol (PVA) into the system enhances the rubbing and washing fastness of the resultant structural colored fabric. The morphology of the structural color fabric was investigated by scanning electron microscopy (SEM), and the thickness of the films corresponding to the different colors were determined. This innovative approach presents a novel methodology for the development of robust structural color films.

The liquid colloidal photonic crystal (PC) is a new kind of photonic structure with attractive properties, such as fluidity, structural metastability, and reversibility in colloidal assembly. However, its controllable synthesis is a big challenge, because it is very difficult to keep all the particles well-dispersed in a highly concentrated colloidal system, and then assemble them into colloidal crystals. In this work, a liquid–liquid extraction (LLE) method has been developed to produce liquid PCs via simple mixing and liquid phase separation at room temperature. Single- and two-component extractants are used to extract part of the solvent from a diluted colloidal solution, which effectively concentrates the colloidal solution without inducing any aggregation and produce highly crystalline liquid PCs by spontaneous precipitation. Compared to the conventional methods, this new LLE process provides a quick, convenient, scalable and universal synthesis of liquid PCs composed of different colloidal particles and solvents, which lays a solid basis for its application in structural-color displays, sensors, and coatings.
