Two-dimensional (2D) nanosheet materials (MXenes) have unparalleled advantages in the field of flame-retardant multifunctional composites, but their dispersibility, flame retardancy and compatibility with the matrix are poor and need to be enhanced. In this research, we employed interfacial decoration and grafting modification to firstly introduce proanthocyanidins (PCs) onto MXenes surface (forming PC-MXenes) to increase the number of available active sites. On this basis, phosphorylated A-POSS was grafted onto PC-MXene (resulting in PAP@P-MXene) via a one-pot method, organic–inorganic hybrid flame-retardant PAP@P-MXene nano-coatings were subsequently constructed on the surface of cotton fabrics via an immersion method, and their structure-property relationships were verified. Thermogravimetric analysis (TGA) results revealed that PAP@P-MXene displayed a high char residue content of 32.0 % at 800 °C, illustrating its pretty good fire-safety properties. Typically, the residual char amount of coated cotton fabric with 12 wt% PAP@P-MXene (C-PAP@P-MXene-3) under a N 2 atmosphere was as high as 37.1 %. Additionally, the limiting oxygen index (LOI) increased to 31 %, while the peak heat release decreased by 79.83 %. C-PAP@P-MXene-3 also displayed a UL-94 V-0 rating and self-extinguishing ability, all of which demonstrated excellent fire safety performance. The unique 2D nanosheet structure of MXenes, along with their innovative structural design and synergistic flame-retardant strategy, endows the nanomaterials with good dispersibility and flame-retardant effects, which has led to the development of new flame-retardant strategies and expanded the potential applications of MXene materials.

SUMMARY Phloridzin has various functions, including antioxidant properties and the treatment of diabetes, and has long been used in pharmaceutical and physiological research. The glycosylation of phloretin is a key step in the biosynthesis of phloridzin. In this study, a genome-wide association study (GWAS) based on phloridzin content was applied, and the key gene GhUGT88F3 for phloridzin-specific biosynthesis was identified in cotton. A single-base deletion in GhUGT88F3 in haplotype I caused a frameshift mutation, leading to premature translation termination and a significant reduction in phloridzin content. Molecular docking revealed important amino acid residues for GhUGT88F3's UDP-glucose transfer activity. Additionally, the transcription factor GhMYB330 was found to positively regulate GhUGT88F3 expression through population transcriptome analysis and LUC experiment. Moreover, phloridzin content was significantly elevated in both GhUGT88F3 and GhMYB330 overexpression transgenic plants. This study expands the diversity of UDP-glucosyltransferases in plants and offers a potential strategy for the sustainable production of bioactive compounds with therapeutic potential.

The unprecedented pandemic has highlighted the need for textiles that rapidly inactivate pathogens to protect public health. However, how to achieve rapid, effective and durable pathogen inactivation with the minimum antimicrobial dose loading has become a major challenge for cotton fabric modification. Here, a surface engineering cotton fabric (Co-CMC@Cu 2+ ) was prepared by grafting carboxymethyl chitosan (CMC) onto cotton fabric and then loading with Cu 2+ via coordination. The Co-CMC@Cu 2+ with minimal copper ion dosage achieved rapid inactivation, excellent comfort, good biosafety, and durability. Specifically, Co-CMC modified with 12.5 mmol/L copper ion solutions achieved impressive bacterial reduction (BR) rates of 94.3 % and 89.3 % against E. coli and S. aureus , respectively, within 10 min of contact. Moreover, the bacteria were completely eradicated after 2 h of continuous contact. Additionally, Co-CMC@Cu 2+ achieved excellent phage reduction (PR) rates of 98.9 % and 100 % against phi6 and phi-x174 bacteriophages, respectively, within 30 min of exposure, highlighting its potential for viral inactivation. Furthermore, Co-CMC@Cu 2+ demonstrated exceptional durability for pathogen inactivation, with BR and PR values above 80 %, even after 150 washing cycles. This novel antimicrobial and antiviral cotton fabric will be a promising candidate textile to protect public health during a pandemic.

Superhydrophobic cotton fabrics have received much attention in recent years. They have been constructed usually by lowering surface energy and increasing surface roughness. Because of the significant environmental harm caused by fluorine-containing reagents, difficult preparation techniques, and low wear resistance, finding a simple approach to prepare a fluorine-free, wear-resistant, strongly sticky superhydrophobic cotton fabric remains a challenge. In this study, we describe a fluorine-free superhydrophobic cotton fabric using the simple preparation approach of immersion, which creates nanoscale siloxane aggregates dispersible in organic solvents. The modified cotton fabrics are characterized by scanning electron microscopy, fourier-transform infrared, and energy dispersive spectroscopy. Excellent superhydrophobicity (ultrahigh water contact angle is 165.2° and sliding angle is 7.2° as well as excellent self-cleaning properties) has been easily applied to cotton fabrics. Superhydrophobic cotton fabrics also have good anti-fouling properties for many common types of liquids, such as milk, coffee, cola, etc. It has been established that these waterproof coatings exhibit outstanding mechanical endurance against water impact, abrasion, and laundering. Superhydrophobic fabrics have a wide range of possible uses due to their readily available coating materials, simple application technique, and strong mechanical endurance. Graphical abstract

With the development of material science, pH-responsive fabric emerges as a novel material in recent years. Effect of chain density and chain length on the conformation transition of surfaceanchored polymers is a fundamental problem which relates to their functionality. In this work,
poly(acrylic acid) (PAA) was grafted onto cotton fabrics through surface-initiated atom transfer radical polymerization (ATRP) technique. The chain length of PAA was modulated by monomer concentration, and the grafting density was regulated by the density of amino groups on the fabric surface.
Contact angle analysis, IR measurement and water uptake observation were employed to study the pH-responsive behavior of the PAA modified cotton. Fabrics with polymers of a larger molecular weight and optimal grafting density exhibited better pH-responsibility. This study provided a structure-property
fundamental understanding on the important parameters influencing the pH-responsibility of PAA modified cotton fabric.

Aphis gossypii Glover (Homoptera: Aphidinae), a major pest of Chinese pepper (Zanthoxylum bungeanum Maxim), causes significant agricultural damage. Ginger (Zingiber officinale Roscoe) has shown potential as a source for developing botanical pesticides due to its strong bacteriostatic and insecticidal properties; however, the underlying mechanisms remain poorly understood. This study evaluated the repellent activity of ginger shoot extract (GSE) across four solvent phases—petroleum ether, trichloromethane, ethyl acetate, and methanol—against A. gossypii. The results demonstrated that GSE exhibited significant repellent effects, with the methanol phase showing the most pronounced activity. Twelve fractions were chromatographically separated from the methanol phase, and electroantennography (EAG) analysis revealed that fraction 4 induced strong EAG responses in both winged and wingless aphids. Further identification of active compounds in fraction 4 by gas chromatography–mass spectrometry (GC–MS) indicated the presence of terpenes, aromatics, alkanes, esters, and phenols as major constituents. Subsequent EAG analysis identified several key compounds—octahydro-pentalene (C1), (Z)-cyclooctene (C2), dimethylstyrene (C3), tetramethyl-heptadecane (C5), tetrahydro-naphthalene (C6), and heptacosane (C9)—as responsible for eliciting EAG responses in both aphid forms. Additionally, results from Y-tube olfactometer assays showed that (Z)-cyclooctene and heptacosane were significantly attractive, while octahydro-pentalene acted as a strong repellent to both winged and wingless aphids. These findings offer valuable insights for the development of synthetic attractants and repellents for A. gossypii and provide a theoretical foundation for utilizing ginger in the creation of botanical pesticides targeting this pest.

A novel adsorbent is prepared from waste cotton fiber by a simple pyrolysis-activation process, and it can efficiently adsorb many kinds of organic pollutants (cationic/anionic dyes and antibiotics etc.). The obtained cotton-based activated carbon (CAC) with large specific surface area (3709 m 2 g −1 ) and suitable pore structure provide abundant active sites and fast channels for the adsorption of pollutant molecules. Its saturated adsorption capacities towards methylene blue, Congo Red and tetracycline hydrochloride at room temperature can reach to 2331, 7265 and 1250 mg g −1 , respectively. In addition, the optimal sample also exhibits excellent adsorption ability towards Rhodamine B (1327 mg g −1 ), methyl orange (955 mg g −1 ) and ciprofloxacin hydrochloride (824 mg g −1 ). The adsorption involves a multi-process including pore filling, Van der Waals force interaction, electrostatic attraction, hydrogen bond formation, surface complexation and π-π stacking etc. The CAC adsorbent also exhibits excellent resistance to environmental disturbances (pH, coexisting ions and multicomponent systems etc.) and good regeneration/recycling performance. This study develops a high-efficiency biomass-based adsorbent with excellent adsorption performance and application generality, which has great potential in wastewater treatment.

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.

In this study, agricultural waste cotton stalk was used as biomass carbon source, calcined with TiO 2 at a high temperature, deposited in a TiO 2 lattice, and used as an electron acceptor to inhibit photogenerated electron recombination. Subsequently, it underwent secondary calcination with g-C 3 N 4 to form a C-TiO 2 /g-C 3 N 4 composite catalyst. Experimental results showed that the coupling of carbon-doped TiO 2 and g-C 3 N 4 accelerated photogenerated electron–hole pairs pair migration, effectively inhibited the recombination of photogenerated carriers, and thus improved the removal efficiency of methylene blue (MB) and tetracycline hydrochloride (TC). Upon irradiation with a 500 W xenon lamp, the degradation rates of MB and TC achieved were 92.6 % and 95.3 % in 90 min, respectively.

Achieving multifunctional integration with comfortability and durability comparable to conventional textiles is one of the ultimate pursuits of personal protective wearables. Herein, a multi-protective textile with breathable, moisture-permeable and washable properties is reported, which is realized by cross-linking of electroactive MXene@gallic acid (MG) with the cationized cotton. Cationic modification reduces the charge repulsion between MG and cotton fibers, and promotes the deposition of conductive media on textile surface. After borax (STB) cross-linking, the obtained textile exhibits superior service stability and can be subjected to conventional washing, exhibiting antioxidant stability during natural storage. Importantly, the cross-linked textile inherits the properties of good breathability, softness and bendability as the original fabric. With the outstanding conductivity (260 mS/cm) and high absorptivity of the solar spectrum (0.920), the textile was used for Joule heating and solar heating, demonstrating their potential in the field of thermal management. Meanwhile, the textile demonstrates excellent antibacterial activity against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus , and maintained satisfactory antibacterial effect (>90 %) even after ten washing cycles. This facile strategy for fabricating personal protective textiles, based on cross-linking cotton fiber with electroactive mediators offers favorable durability, comfortability and multifunctionality, providing a scalable and sustainable approach for manufacturing multi-protective wearables.

3D printing technology is highly regarded in the textile and apparel industry for its rapid manufacturing and customization capabilities. However, the current 3D printing materials employed in this field can limit printed fabrics with restricted flexibility and comfort, creating a notable disparity compared to traditional textiles. To address this limitation, the study focuses on utilizing cotton fibers as the raw material for 3D printing textiles. Herein, cotton fibers were dissolved in a LiCl/DMAc solvent, with the incorporation of hydroxyethyl cellulose to adjust the printability of the ink. Materials extrusion technique was employed for the printing process. This work involved optimizing dissolution, adjusting ink viscosity , and selecting post-processing methods for the printed fabrics. A comparative investigation of the wear properties of printed cellulose fabrics, cotton fabrics, and 3D printed fabrics from thermoplastic materials was conducted. The results indicate improvements in the flexibility, breathability, and moisture absorption of 3D printed cellulose fabrics compared to existing 3D printed fabrics. Additionally, these 3D printed cellulose fabrics demonstrate superior abrasion resistance when compared to cotton fabric. As a proof of concept , garments and gloves were successfully prepared using 3D printed cellulose fabrics, expanding the use of textile materials in 3D printed textiles. This innovative approach holds promising prospects for 3D printing flexible fabrics and garments.

Oiled wastewater generated from industrial processes inflicts significant harm on the environment, posting a pressing need for affordable materials that provide prospect for effective oil-water separation and the recovery of valuable oil resources from such wastewater. The incorporation of zeolitic imidazolate framework (ZIF) onto the commercial cotton fabric, due to its porous structure and adjustable properties, offers a promising solution to this challenge. In this work, a cotton fabric with multifunctionalities was designed by in situ growing ZIF-67 onto cotton (ZIF-67@Cotton). The robust superhydrophobic surface was successfully created on ZIF-67@Cotton by combining a self-roughness structure with the modification using a low surface energy agent. This modification imparts versatility, enabling self-cleaning, high-efficiency oil-water separation, and mechanical stability. The resulting ZIF-67@Cotton exhibits a desirable water contact angle (WCA) superhydrophobic characteristic (over 156°), and exceptional resistance to mechanical abrasion during laundering. Notably, this superhydrophobic ZIF-67@Cotton not only efficiently extracts oil from oil/water mixtures with a efficiency over 99.5 % and water-in-oil emulsion (99.3 %) after repeating 20 times but also exhibits superior UV resistance which introduces an innovative approach to develop next-generation multifunctional flexible fabrics featuring superhydrophilic and underwater superoleophobic surfaces.
