Cotton fabric is widely used for its excellent wearability but often suffers from drawbacks such as poor stain resistance, susceptibility to corrosion, and low colorfastness. Here, we introduce a novel method to create colorful superhydrophobic cotton fabric using octadecylamine-modified dialdehyde cellulose (DAC/ODA) particles as building units, which are synthesized via a Schiff base reaction and subsequently dyed with active dyes. Leveraging the film-forming ability of ODA and the affinity between cellulose materials, DAC/ODA formed a robust coating on the cotton surface, with its microstructure precisely controlled through thermal induction. The resulting fabric (DAC/ODA/Cotton) exhibited exceptional superhydrophobicity, with a water contact angle of 155° and an osmotic pressure of 426.2 mm. The uniform coverage of DAC/ODA on cotton fibers also ensured high air permeability (33.1 mm/s). Additionally, DAC/ODA/Cotton demonstrated outstanding antifouling performance against various common liquids and water can easily remove dust from its surface. Importantly, the fabric maintains its superhydrophobicity under extreme conditions such as high temperature, UV radiation, and acid-base exposure. Even after 100 abrasion cycles, no significant changes in surface morphology and color on DAC/ODA/Cotton were observed. This fluorine-free, environmentally friendly approach offers significant potential for developing multifunctional textiles and coatings with broad applications while reducing environmental impact.

Phosphor-converted white LEDs rely on combining a blue-emitting InGaN chip with yellow and red-emitting luminescent materials. The discovery of cyan-emitting (470–500 nm) phosphors is a challenge to compensate for the spectral gap and produce full-spectrum white light. Na 0.5 K 0.5 Li 3 SiO 4 :Eu 2+ (NKLSO:Eu 2+ ) phosphor was developed with impressive properties, providing cyan emission at 486 nm with a narrow full width at half maximum (FWHM) of only 20.7 nm, and good thermal stability with an integrated emission loss of only 7% at 150 °C. The ultra-narrow-band cyan emission results from the high-symmetry cation sites, leading to almost ideal cubic coordination for UCr 4 C 4 -type compounds. NKLSO:Eu 2+ phosphor allows the valley between the blue and yellow emission peaks in the white LED device to be filled, and the color-rendering index can be enhanced from 86 to 95.2, suggesting great applications in full-spectrum white LEDs.

Personal thermal management (PTM) technology, which predominantly utilizes phase change materials (PCMs) has emerged as an effective strategy for mitigating thermal stress. However, how to impart intrinsic flexibility and vibrant colors to meet practical application needs remains a topic that requires further research and effort. In this thesis, a novel intrinsically flexible PCM with notable shape stability, vivid and eye-catching colors for PTM was synthesized. The flexible PCMs demonstrate a high phase change enthalpy (102.1 J/g), while maintaining thermal stability over 100 cycles. In addition, they can chemically bond with dye molecules, displaying vivid colors with extremely low dye usage (0.05 wt%). The integration of PCMs with fabrics using a hot press method produces a fabric that closely conforms to the human body and exhibits strong colorfastness, demonstrating significant potential for thermal management in specialized garments.

Monodisperse quantum dots (QDs) were prepared by low-temperature process. The remarkable narrow emission peak of the QDs helps the liquid crystal displays (LCD) and electroluminescence displays (QD light-emitting diode, QLED) to generate wide color gamut performance. The range of the color gamut for QD light-converting device (QLCD) is controlled by both the QDs and color filters (CFs) in LCD, and for QLED, the optimized color gamut is dominated by QD materials.

Clean production of fluorine-free and colorful superhydrophobic surface coating has been highly demanded in many applications but still faces many major challenges. Herein, a one-step clean coating process has been developed to make robust fluorine-free superhydrophobic coating with outstanding color fastness and self-healing property. The coating system comprises cycloolefin copolymer polymer (COC), hexadecyltrimethoxysilane (HDTMS), hydrophobic functionalized TiO 2 nanoparticulates and dyeing pigments. Janus cotton fabrics are prepared by applying the TiO 2 -HDTMS/PB/COC composite coating solution onto the facing side of the fabric by an electrospraying technique. The coated fabric side demonstrates superhydrophobicity showing water contact angle (WCA) of 167.3° ± 2.2° and sliding angle (SA) of 6.9° ± 0.5°, while the un-coated side still retains its original hydrophilic property. The coating shows excellent color fastness and strong bonding strength that can withstand many severe treatments with little affection on color and superhydrophobicity. The coating's original superhydrophobicity can be restored from chemical or physical damages. The developed coating system have also been applied to many other substrates (e.g. polyester, wool, mesh membrane, sponge, etc.). More importantly, the process has low energy consumption with almost no waste liquid produced during the coating process. This simple yet clean coating strategy meets the requirements of green and low energy dyeing, and will benefit the development of robust multifunctional coating .

Textiles that can repeatedly change color in the presence of external stimuli have attracted great interest. Effectively designing to produce such functional textiles is essential, yet there remain challenges like producing stable coloration, rapid response, and reverse color changing. Here, the preparation of a magnetic field response (MFR) textile with a fast magnetic field response, brilliant structural coloration, and mechanical robustness is reported. The MFR textile is knitted by incorporating magnetic particles’ ethylene glycol (EG) suspension within polydimethylsiloxane (PDMS)-based fibers. A surface modification strategy is designed to prevent EG from seeping out along the PDMS polymer chains. A PDMS fiber is encapsulated in waterborne polyurethane, and a polydopamine joint layer is used. The MFR textile demonstrates magnetic field-triggered structural colors, and the breaking strength and elongation at break of each composite fiber are improved. In addition, multishaped patterns can be printed on the MFR textile with the help of the photo etching technology, which enhances the applications of the new functional textiles.

Many Chinese medicines have shown protective effects on the heart, while their specific effects and modes of action are still lacking of intuitive studies. In this paper, we propose a structural color heart-on-a-chip from layer assembly for evaluating the myocardial protection effects of traditional Chinese medicine. The structural color scaffolds are imparted with a striped microstructure on one side for inducing the alignment of cardiomyocytes, and an inverse opal nanostructure on the other side for optical sensing. Because the scaffold could generate obvious color changes upon cardiomyocyte contraction, its integration into a microfluidic chip provides a simple screening platform to study the pre-protective effects of Chinese medicine against cardiac injury. We have demonstrated that with the induction of doxorubicin, the injured cardiomyocytes presented abnormal morphology, disappeared sarcomere and depressed beating behaviors that could be reflected by reduced structural color changes. On the contrary, traditional Chinese medicine pre-protection can increase the vitality of cardiomyocytes, reduce reactive oxygen species production, and improve the contractile function of cardiomyocytes, which is highly consistent with the known conclusion. These results indicated that our structural color heart-on-a-chip with real-time visualization characteristics could provide an ideal platform for traditional Chinese medicine development and drug screening.

A significant amount of wastewater is generated in printing and dyeing processes of nylon textiles . The wastewater pollutes the environment and increases the post-treatment costs. To simultaneously obtain the excellent dye utilization and color fastness, low-water-soluble reactive dyes (LWSRDs) with vinylsulfone group as a reactive group were developed in this paper. The LWSRDs have dual characteristics of high exhaustion and forming covalent bonds with nylon fibers in neutral conditions. These characteristics result in higher fixation on nylon 6 traditional fibers (NTF) using Traditional dyeing process (TDP) compared with commercial reactive dyes. Based on the characteristics of LWSRDs, modified dyeing process (MDP), which was conducted in one-pot, significantly reduces the costs of chemicals and wastewater. Moreover, the fixation of LWSRDs on nylon fibers using MDP was higher than that using TDP. Notably, the dyed nylon fibers were uniform and vibrant, and demonstrated exceptional color fastness against washing and rubbing, exceeding grade 4. The results of innovative LWSRDs and their corresponding MDP offer an effective approach to dyeing nylon fibers, with good application prospects in dyeing industry.

Conventional textile dyeing relies on the use of dyes and pigments, which can cause severe environmental contamination and waste a large amount of water. Structural coloring is one of the effective ways to achieve environmentally friendly coloring of textiles. In this work, three plant polyphenols with the same o -benzenetriol structure (tannic acid (TA), gallic acid (GA), and tea polyphenol (TP)) were selected as raw materials. Three plant polyphenols can quickly form nanofilms at the gas-liquid interface through a Schiff base reaction with polyethyleneimine (PEI) under mildly alkaline conditions, which were deposited to the surface of silk fabric, allowing precise control over the thickness of film by adjusting the time, resulting in various structurally colored silk fabric. This method for creating structural colors is not substrate-specific and enables the quick production of structural colors on various textile substrates. Furthermore, the structural color silk fabric based on plant polyphenol has antibacterial performance. This textile coloring method is simple, cost-effective and environmentally friendly, providing a new approach to eco-friendly textile dyeing.

Carbon fibers (CFs) are widely used in various cutting-edge fields, such as aerospace, military, automobiles, and sports, owing to their unique combination of excellent mechanical properties, good thermal stability, and lightweight. However, their inherent super-black appearance makes it difficult to satisfy the aesthetic/fashion requirements of the colorful world, and the flammability of CFs severely limits their practical utilization in high-temperature and other extreme environments. Herein, we fabricated full-color tunable colored CFs on a large-scale via atomic layer deposition, based on the monolayer film interference strategy. CFs exhibited brilliant colors and excellent environmental durability in extreme environments, such as intense ultraviolet (UV) irradiation, accelerated laundering, friction, high-temperature, and low-temperature treatments. Colored CFs also exhibited excellent fire-retardant performance that could withstand alcohol-lamp flame burning for 60 min. Our work provides insights into an innovative material/structural design that can help achieve rapid development of the CF industry and global carbon neutrality/sustainability. Graphical Abstract

Structural coloration is an important way to realize eco-friendly dyeing of textiles. Structural colored cotton fabric was obtained by fabricating a polydopamine (PDA) film on the white cotton fabric at different polymerization reaction times. PDA is prone to generate capillary tension during film formation, which damages the uniformity and interfacial bonding force of the film. Multiple hydrogen bonds will form between the lactam group of polyvinylpyrrolidone (PVP) and the phenolic hydroxyl group of PDA. The introduced hydrogen bonds will effectively enhance the interfacial bond strength and lead to structural color with high color fastness. The surface morphology of double-layer aggregates of the PDA film on structural colored cotton fabric was revealed by scanning electron microscopy. The chemical constitution of the PDA film and PVP was investigated by Fourier transform infrared spectroscopy and X-ray diffraction. The color characteristics of structural colored cotton fabrics were analyzed by UV–vis reflectance spectroscopy and spectrophotometry.

Biomimetic construction of structural colors on materials as an environmentally friendly coloring method has received more and more attention. If the structural color of the materials has special functions, it will broaden the application field. However, functional structural colors are usually prepared through the coassembly of building units with functional agents or functional modification of structural colors. In this study, poly(2,2,3,4,4,4-hexafluorobutyl acrylate/methyl methacrylate/[3-(methyl acrylamide) propyl] trimethylammonium chloride) (PAMM) microspheres containing hydrophobic and antibacterial functional groups were prepared, which were used to construct multifunctional structural colors on black polyester fabrics through the atomization deposition method. PAMM microspheres with different particle sizes (332.1, 318.3, 302, 289.9, 257.2 nm) were successfully prepared by adjusting the amounts of monomers in the synthesis reaction, which can form different structural colors of pink, green, cyan, blue, and purple on the polyester fabrics. The fabrics with structural color can significantly inhibit the growth of E. coli and S. aureus, and the antibacterial rates of both are greater than 94%. The fabrics with structural color showed outstanding hydrophobicity with a static water contact angle greater than 140°. This research provides an idea for the preparation of multifunctional fabrics with structural colors through the synthesis of building units of polymer microspheres with multifunctional groups.
