The long-term fixation of mineral pigments in ancient paintings has always been a challenge. Gelatin alum solution (GAW), as a traditional pigment fixative, presents good pigment fixation in the early stage of use, but its poor durability is well known. In this work, a microgel (SH 1:1 ) prepared from sodium alginate and hydroxyethyl cellulose was proposed to replace GAW for the pigment fixation due to its micro scale, strong adhesion, and good chemical stability. The evaluation results indicate that SH 1:1 microgel can endow the treated unstable pigment samples with better fixation effect and durability. Especially after 10 days of temperature humidity alternating aging, the SH 1:1 treated samples show smaller morphological changes and higher retention rates of tensile strength and folding endurance (98.5 % and 79.2 %) than those of GAW treatment (96.5 % and 46.5 %). The excellent fixation effect is attributed to SH 1:1 microgel's strong bonding strength to mineral pigments and paper fibers. Moreover, the outstanding durability is due to the good aging resistance, water retention and mild alkalinity (pH = 7.0–7.5) conferred by SH 1:1 treatment, preventing rapid failure of fixative, as well as preventing paper acidification and degradation. Therefore, SH 1:1 microgel has great application potential in restoring antique paintings.

This paper reports the syntheses of a series of polychromatic pigments with the general formula LiAl 1- x M x (MoO 4 ) 2 (M = Fe, Pr, Ho, Nd, Er, Ce; x = 0–0.4) and the characterization of near-infrared reflectance properties. The synthesized pigments exhibited green (Pr), lavender (Nd), pink (Er) and different yellows (Fe, Ho, Ce). The XRD patterns of typical LiAl 1- x Fe x (MoO 4+δ ) 2 samples show that the prepared samples are triclinic lithium aluminum molybdate structures with space group P -1.The iron in the sample mainly existed in the form of Fe 3+ , which led to the directional growth of grains with different morphologies. The near-infrared solar reflectance (R*%) of LiAl 1- x Fe x (MoO 4 ) 2 pigments reached 94.19%. As the doping concentration of rare earth was increased, the color of the pigments gradually deepens. By introducing rare earth elements Pr, Ho, Nd, Er, and Ce into the LiAl(MoO 4 ) 2 matrix, the color of the pigment was successfully changed from white to green, lavender, pink, and yellow, indicating that doping can control the color of the pigment. Moreover, the prepared pigments had high R*% (>87%), indicating that the pigment samples have excellent thermal insulation properties and can be used as a new type of reflective thermal insulation coatings.

Inkjet printing technology is widely used in the textile digital printing application today though the current technology still requires pretreatment and postwashing procedures before and after printing. Additional chemical treatment generates a large amount of wastewater and complicates the process. Among the many potential approaches for reducing chemical waste, pigments with self-dispersing capability were prepared and formulated into binder-free inkjet inks that require no pretreatment or after-washing process when printing cotton fabrics. The new self-dispersing pigment inks were tested and evaluated on cotton fabrics. The distribution of particles was between 122.2 and 188.5 nm, and inks have excellent storage capability. Printed fabrics’ light fastness and acid/alkali resistance are about grade 5, and printed cotton’s washing and rubbing fastness are above grade 3. The mechanism and performance of ink drops were investigated by LF-NMR and ink-drop observation methods. This work provides a possible solution for reducing wastewater in the textile industry.

Wooden figurines were excavated from the tomb of the Princess Yongtai of the Tang Dynasty. A series of analytical techniques were employed to understand the craftsmanship of wooden figurines during the Tang Dynasty. The pigments, cross-sections, and adhesives were analyzed using energy X-ray fluorescence spectrometry (EDX), micro-Raman spectroscopy, polarized light microscopy (PLM), X-ray diffraction (XRD), and pyrolysis–gas chromatography–mass spectrometry (Py–GC/MS). The results demonstrate that the pigments were primarily cinnabar, malachite, azurite, goethite, carbon black, and anglesite. The cross-sectional images show that the painted layer of the wooden figurines includes pigment and preparation layers. The main component of the preparation layer was mendipite. Chinese wax, animal glue, and benzoin were used as adhesives. This study provides scientific support for antiquarians and a basis for the protection and repair of this valuable world cultural heritage site.

In this paper, a series of high performance near-infrared reflective pigments based on Bi 3 YO 6 doped with Fe 2 O 3 and Tb 4 O 7 were prepared by high-temperature calcination method. The pigments were characterized by some analytic techniques, such as XRD , Particle size analyzer, SEM, EDS , UV–vis–NIR spectrophotometer, CIE L*a*b* (1976) color space and infrared thermal imaging. Experimental results showed that the Fe 2 O 3 doping in Bi 3 YO 6 could change the color from bright yellow to ochre red. The substitution of Tb (IV)-doped pigments changed the color to dark orange. The doping of Fe (III) and Tb (IV) contributed to enriching the color diversities of pigments. Among the synthesized pigments, Bi 3-x Fe x YO 6 and Bi 3 Y 1-x Tb x O 6+δ displayed a disordered defective fluorite-type structure. The effect of doping Fe (III) and Tb (IV) reduced the near-infrared reflectance of the pigment. Excepting for Bi 3-x Fe x YO 6 (x = 0.8), the near infrared reflectance of some other pigments were higher than the China National standard (CNs). Chemical resistance tests showed that the pigments had excellent acid and alkali resistance. Finally, the application practical of traditional iron oxide yellow pigment and three prepared pigments, i.e., Bi 3 YO 6 , Bi 3-x Fe x YO 6 (x = 0.4) and Bi 3 Y 1-x Tb x O 6+δ (x = 0.05) were studied and compared by infrared thermal imaging. The test results showed that Bi 3 YO 6 still had a strong near-infrared reflection effect after being painted. Compared with traditional iron yellow pigment, Bi 3 YO 6 could reduce the surface temperature of galvanized sheet by 20 °C under the illumination of infrared light. The series of Fe (III) and Tb (IV) doped pigments prepared in this paper have revealed some promising application values.

Lignin is a promising dispersant due to its hyperbranched polymer structure, low cost, renewability and abundant availability. However, its use is limited by its broad molecular weight distribution, inhomogeneity, and low content of hydrophilic functional groups. In this work, lignin was functionalized with alkaline amino acids (EHL-AA) to enhance water solubility and molecular weight uniformity. The results showed that EHL-AA significantly improved the dispersion of pigment Red 57:1 (P.R.57:1) in aqueous solutions, reducing the required dosage by 50 % compared to commercial small-molecule dispersants. Additionally, histidine modified lignin (EHL-His) exhibited superior stability for P.R.57:1 compared to commercial lignosulfonate (REAX 85A). Molecular dynamics simulations further revealed that showed that EHL-His had the highest electrostatic potential difference and the largest absolute value of negative ESP. The adsorption of EHL-His onto the P.R.57:1 surface followed the pseudo-second-order kinetic model and the Langmuir model, with EHL-His showing a higher Langmuir constant (b) than REAX 85A, indicating the strongest interaction with the pigment. In summary, this work advances pigment dispersion technology and promotes the high-value utilization of lignin.

The pigments with high near-infrared (NIR) reflectance hold great promise toward both fundamental types of researches and applications for the realization of comfortable indoor-temperature by mitigating urban heat island effect. However, the facile yet simple method for the NIR reflective pigments with bright color and non-toxic feature remains a huge challenge, limiting their practical application. Herein, we proposed a mild and universal method of solution combustion for constructing the non-toxic and NIR reflective yellow-green pigments of Al-doped Y 3 Fe 5 O 12 . The Y 3 Fe 4 AlO 12 pigment presented a high NIR reflectance of 87.66%, and an outstanding acid/alkali resistance. Moreover, the pigment had an impressive color performance (L* = 78.72, a* = − 4.05, b* = 40.04). Besides, the practical near-infrared reflection performance revealed that the transient surface temperature of the Y 3 Fe 4 AlO 12 pigment was 7.6 °C lower than that of the pigment with similar color on the market. This research supplied high NIR reflecting pigments of Y 3 Fe 5−x Al x O 12 as promising coatings for roofs and exterior walls of buildings, acting as a favorable solution for urban heat island effect.

Yttrium ferrite (YFeO 3 ) is highly attractive as a promising multiferroic material and also has been proven to have potential in the field of near-infrared reflective cold pigments. In this work, YFeO 3 powders were fabricated via metal citrate xerogel mediated molten salt procedure at different temperatures. The complexation process of the metal citrate xerogel as a precursor was promoted by the salt medium, and the molten salt medium reduces the reaction temperature to obtain morphologically distinctive YFeO 3 without impurity. The orange YFeO 3 powders possessed outstanding near-infrared reflection characteristics and high solar reflectance. The relationship of particle size, particle shape, charge state distribution, magnetic performance and near-infrared reflection performance of YFeO 3 was investigated. Specifically, with the increase of calcining temperature, particle size increases, thereby increasing the infrared reflectivity. The rising in the amount of Fe 2+ –Fe 3+ ion pairs increased the absorption of free carriers, thereby reducing the infrared reflectivity. The two factors contributed together to the near-infrared reflectivity, which first increased and then decreased with the increase of calcining temperature. In addition, the increase in the ratio of Fe 2+ also hindered the super-exchange and Dzyaloshinskii–Moriya interaction of Fe–O–Fe, thereby improving of the weak-ferromagnetic behavior of YFeO 3 .

A fluorine-free route has been developed to fabricate V/Pr co-doped zircon (ZrSiO 4 ) ceramic pigments with Na 3 VO 4 and Pr(NO 3 ) 3 ·6H 2 O as colourants . The as-prepared pigments were characterized by XRD , Raman, XPS , UV–vis, FE-SEM, TEM and automatic colourimeters . The results show that Na 3 VO 4 can not only act as colourant to produce blue hue, but as mineralizer to accelerate the formation of V/Pr co-doped ZrSiO 4 pigment. A colour tuning between blue, green and yellow can be achieved by increasing the mole ratio of Pr/V, and the most intense yellow hue (L* = 74.55, a* = −0.38, b* = 46.82) is obtained at a mole ratio of Pr/V = 0.5. Both Pr 4+ and Pr 3+ cations are co-existed in the pigments, where Pr 4+ contributes to the generation of yellow hue while Pr 3+ undermines the yellow hue. The good chromatic ability in glaze at high temperature suggest its potential application in ceramic decoration.

Molecular sieves were widely used in the chemical industry, which caused a large number of inactivated molecular sieves to be discarded, resulting in a serious waste of resources and environmental pollution. Recently, recycling of discarded molecular sieves (DMS) has become a research hotspot. This study proposes an economical method using DMS to prepare green pigments mimicking foliage spectrum. The synthesized products were subjected to characterization using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Ultraviolet-visible-diffuse reflectance spectroscopy (UV-Vis-DRS), and scanning electron microscopy (SEM). The analysis revealed that sulfur radicals can be effectively incorporated as chromophores within the β-cages that are formed during the recrystallization process of sodalite, these cages are highly conducive to accommodating the radicals, thereby providing a protective environment that shields them from external influences. By adjusting the mass ratio of Na 2 CO 3 /S, the visible reflectance spectrum of ultramarine pigments can be easily modified. In addition, camouflage coating based on ultramarine green can be used to simulate the spectral reflectance characteristics of green vegetation. The Spectral Angle Mapping (SAM) system was used to evaluate the simulation effect of the camouflage coating. At a threshold below 98.5%, the camouflage coating still be misidentified as leaves, this method can recycle massive solid waste resources and significantly reduce the preparation cost of imitation green vegetation camouflage pigments.

Magnetoplumbite-type oxides display various properties and find applications in multiple fields. In this study, a novel magnetoplumbite-type solid solution BaZn 6- x Ni x Ti 6 O 19 (0 ≤ x ≤ 4) with vivid green color was synthesized through a high-temperature solid-phase method for the first time. The as-synthesized BaZn 6- x Ni x Ti 6 O 19 solid solution crystallizes in the space group of P6 3 / mmc . The solid solution exhibits excellent green property, and its color is adjustable with increasing doping levels of Ni 2+ . The depth of color originates from the content and position of Ni 2+ in the solid solution. BaZn 6- x Ni x Ti 6 O 19 is suitable for PMMA (Polymethyl methacrylate) pigment and hydrophobic coating. Colored PMMA containing BaZn 6- x Ni x Ti 6 O 19 exhibits vibrant colors with high saturation, showing excellent application potential. The hydrophobic coating compounded with BaZn 6- x Ni x Ti 6 O 19 exhibits near-superhydrophobic properties and demonstrates excellent self-cleaning effects under simulated natural environmental conditions.

In this study, we conducted diagnostic research on a precious Yuan dynasty tomb mural painting (A.D.1271–1368) excavated in Chongqing, 2005. To restore the painting, the painting technique and the artwork's preservation state were investigated through optical microscope (OM), portable X-ray fluorescence (p-XRF), micro-Raman spectroscopy (μ-Raman), macro-Fourier transform infrared spectroscopy (macro-FTIR), and X-ray powder diffraction (XRD) analyses. During this process, the coarse ground, fine ground and painting layer were characterized and analyzed. Experimental results show that the compositions of coarse ground are calcite and soil, while fine ground mainly consists of calcite and a few amounts of silicate. We also investigated and identified the pigments and binders used for the painting layers, which revealed that carbon black was used for the black pigment, cinnabar, red ochre and small amounts of red lead were used for the red pigments. To further investigate the distribution of materials in cross-sections with special attention to trace presented organic material, a FPA detector was used for imaging coupled with a large radius germanium crystal equipped attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. It has been found that the protein may be used as the binder and organic additive in mural painting. Our work enhances the understanding of the mural painting technique of the Yuan dynasty and also provides a reference for the future restoration work of paintings.
