The cotton samples were treated by chitosan solution at acidic condition to modify their dyeing properties to anionic coloring materials. By fluorescence spectrum together with FTIR, XRD and TGA analysis, it was concluded that the chitosan molecules could spontaneous transfer from solution onto cotton surface yet would not influence its internal structure. In order to color the chitosan-treated cotton, an anionic polystyrene-encapsulated copper phthalocyanine (CuPc) pigment was prepared in a miniemulsion process. The full encapsulation of nano-pigment could be directly observed by TEM . The encapsulation would not alter the crystal structure and color properties of CuPc while could make the nano-pigment more stable against centrifuge and temperature variation. Finally, the dyeing properties of this encapsulated nano-pigment on chitosan-treated cotton samples were studied. It was indicated the chitosan molecules on cotton had great capability to improve the uptake of encapsulated nano-pigment mainly due to the accessible amino groups introduced.

In this work, we successfully report the design and synthesis of rod-like CoAl 2 O 4 /halloysite hybrid pigment from zeolitic imidazolate framework-67 (ZIF-67, a Co-based MOF) and tubular halloysite via a facile two-step route for the first time. The as-prepared nanostructures were thoroughly characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared reflection (FTIR Spectroscopy), thermogravimetric and differential scanning calorimetry (TG-DSC), X-ray photoelectron spectrometer (XPS), ultraviolet–visible spectrometry (UV–vis) and CIE L* a* b* colorimetric method . XRD patterns indicated that the presence of CoAl 2 O 4 spinel was observed at various temperatures ranging from 800 to 1100 °C. The SEM and TEM images showed that the nano-pigment has a rod-like hybrid structure composed of nano CoAl 2 O 4 particles and SiO 2 . The color performance of the fabricated pigments was evaluated and given suitable color coordinates (L* = 44.72, a* = −14.40, b* = −37.83) and (L* = 42.57, a* = −7.68, b* = −41.14) at the calcination temperature of 1100 °C for 2 h and 3 h, respectively. The mechanism study indicated that these composites were formed by Co 3 O 4 derived of ZIF-67 as highly active cobalt source and Al 2 O 3 decomposed from halloysite substrate as aluminum source. In addition, the corrosion resistance test showed that the CoAl 2 O 4 composites retain crystalline stability, almost no color deviation in CIE chromatic system even after 1 M HCl leaching. Furthermore, the CoAl 2 O 4 /halloysite exhibited excellent thermal and suspension stability, which indicated it could be a promising candidate for ceramic glazes and water-borne coatings. These findings provide insight into a new strategy for the synthesis of clay mineral-based ceramic pigment .

A novel cobalt aluminate (CoAl 2 O 4 ) nanopigments with bright blue color and good dispersibility was fabricated via a coprecipitation process of threonine. Threonin acts as coordination and structure-directing reagents for the nucleation and assembly of hydroxide precursor, limitation of the CoAl 2 O 4 nanoparticle growth during calcination process, and fine-tuning the molar ratio of Co/Al in final products. The products were characterized with XRD , FESEM, TEM , FTIR , DLS, EDX, ICP-AES and UV-vis. The particle size, colorimetric values and printing ink of CoAl 2 O 4 nanopigments with different amount of threonine and without threonine were investigated. The study exhibited that the CoAl 2 O 4 nanopigments with 0.1–0.2 mol/L threonine showed a smaller size of 10–20 nm, better dispersion and color property than other test samples. The coloration mechanism of the CoAl 2 O 4 nanopigments is also discussed.

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.

Enhancing dye utilization and reducing dye emissions are essential goals for the textile industry, achievable by immobilizing dyes on a carrier to minimize dye consumption and wastewater generation. This study introduces silicon-based nano pigment particles (SNPPs) synthesized by immobilizing reactive dyes onto silica nanospheres via (3-aminopropyl) triethoxysilane (APTES). The structure-property relationship between the reactive dye structure and the performance of SNPPs is systematically elucidated. SNPPs achieved adsorption rates exceeding 80 % for K-type reactive dyes (capacity >80 mg/g) and over 90 % for M-type, KN-type, and X-type dyes (capacities >110 mg/g). The particles exhibited high electronegativity (>-60 mV), excellent dispersibility, and stability, with bi-functional reactive dyes demonstrating superior performance due to enhanced covalent interactions. Application in cotton fabric printing and dyeing yielded vivid colors (color strength up to 10.37) and excellent fastness properties (rubbing: 3–4, washing: 4–5, light: 3–5 grades). Furthermore, cotton fabric dyed with recycled SNPPs showed consistent colorimetric performance and color fastness properties across five regeneration cycles. This innovation offers a scalable, eco-friendly solution for textile coloration, aligning with industrial sustainability goals.

Structural colorants for ecological fabric dyeing are typically microscale colloidal arrays involving complex and time-consuming self-assembly, it remains a challenge to perform efficient and large-scale double-sided dyeing on disordered fabric surfaces without sacrificing wearing experience. Innovatively, A photonic nanopigment, composed of hollow silica nanospheres with disordered metasurfaces and high surface-charge is designed to overcome the aforementioned challenge. They individually generate non-iridescent structural colors without self-assembly and disperse uniformly in water. By a one-step dip-dyeing strategy, the photonic nanopigments are quickly and selectively deposited onto the yarn surface of fabrics, achieving high-quality double-sided structural coloration. Meanwhile, constructing a hydrogen bond crosslinking network between the fabric and nanospheres by adhesive and tannic acid greatly enhances colorfastness. Furthermore, the fabrics retain inherent softness and excellent breathability, as nanoscale pigments do not clog weaving holes. Such photonic nanopigments provide a versatile platform for industrial structural coloration of various fabrics with different surface roughness and weaving structures.

To evaluate the barrier properties of the composite coatings reinforced by PDA (polydopamine)-BN@ZnO nano-pigments, the correlation between electrolyte transport characteristics and different nano-pigment contents in the composite coatings was studied. The electrochemical response of composite coatings was mainly controlled by non-Faraday process. A two-layer model based on Young's impedance was established to fit the non-Faraday process of the composite coatings from the 6th day of immersion. The coating resistivity varying with electrolyte transport could be used as a key parameter to describe the barrier properties of the coatings. At the same time, the explanation that different contents of nano-pigments enhance or weaken the barrier performance of composite coatings was given, that is, the nanoconfinement effect of the polymer under the effect of nano-pigments.

Owing to the unique features of high chemical and photostability, structurally colored materials can potentially replace organic dyes and pigments in many applications. The most common fabrication method of structural color materials is the “bottom-up” self-assembly approach. However, the assembled structures are easily damaged by external forces, leading to color fading or even disappearance. Therefore, it is still a challenge to fabricate structural colors that mimic the appearance of absorbing pigments without assembly processes. Inspired by the Steller's jay, non-iridescent structurally colored nanopigments are created, which are composed of hollow SiO 2 (H-SiO 2 ) microspheres with amorphous carbon on the inner wall of the shell and disordered metasurfaces on the shell layer. It is shown that the color originates from the synergistic effect of the disordered metasurfaces and the amorphous carbon layer, which can produce strong coherent scattered light and effectively absorb incoherently scattered light, respectively. Amazingly, the H-SiO 2 microspheres can maintain their structural colors even after grinding or being dispersed in water. What's more, through the additive color mixing of two base colors and precise tuning of their ratios, gradient structural colors that spanning the visible spectrum can be achieved. These features indicate promising prospects for the designed nanopigments.
