The multifunctional textiles are interesting areas to be researched on. In this paper, the effect of the fiber nanocoating on the wrinkle recovery, air permeability and anti-Ultraviolet (UV) property of different woven fabrics using sol–gel method has been studied. The sol–gel method has various advantages over other methods. Along with these properties, no change in visual appearance has also been discussed in this paper. The dispersion of nanoparticles of titanium was obtained into silica sol. The characterization of nanocoating was done using Field emission scanning electron micrograph (FESEM) and Fourier transform infrared spectroscopy (FTIR) studies. The fabric wrinkle recovery properties, air permeability and anti-UV performance were analyzed using three different immersion timings into the nanosol. The results revealed that both wrinkle recovery properties and anti-UV performance have increased with respect to immersing time of the nanocoating although a slight decrease in air permeability and whiteness index of the fabric was also observed.

Silk, a popular luxury textile with many years of history, is easy to embrittle and adsorb bacteria when stored for a long time or exposed to sunlight, which affects its service life. To improve the silk fabrics with excellent antibacterial activity, washing and aging durability, and UV shielding, multifunctional silk fabrics were designed and fabricated via a green finishing approach. Here, we proposed a simple strategy to fabricate silk fabrics with multi-functions via coating clavate-shaped ZnO nanoparticles (ZF-silk fabrics) by dipping and pressing for cycles. The scanning electron microscope (SEM), fourier transform infrared (FTIR), ultraviolet visible spectrophotometry (UV–Vis), and X-ray diffraction (XRD) were used to analyze the structure and properties of fabricated ZF-silk fabrics. Compared with raw silk fabric, the fabricated ZF-silk fabrics represented excellent UV shielding, good tensile strength, and superior antibacterial activity. Notably, the ZF-silk fabrics had good washing stability and aging resistance. In addition, the ZF-silk fabrics possessed superior antibacterial activity before and after aging treatment (under UV radiation for 72 h). Therefore, the durable and multifunctional ZF-silk fabrics indicate great potential for achieving to realize a long service life of the fabrics.

The pH-responsive color-changing indicator films are necessary for the intelligent packaging systems. However, casting and evaporation techniques are usually employed to prepare these indicator films, which are time-consuming and energy-wasting, limiting their large-scale production. Hence, a sol-gel transformation approach was proposed to fabricate cellulose/alizarin composite films by using low-cost waste paper cups as cellulose resource in this work. It was found that cellulose/alizarin composite films displayed homogeneous structures due to the extensive hydrogen bonding between cellulose and alizarin, and their properties varied obviously with the content of alizarin, Specially, the cellulose/alizarin composite films showed noticeable color transition with an increasing pH from 1.0 to 13.0, and cellulose/alizarin composite films with low content (＜7.5 %) of alizarin were much more sensitive to pH change. It was also proved that the as-prepared cellulose/alizarin films possessed good mechanical properties, high UV barrier capacity and impressive antioxidant activity. Particularly, the tensile strength of the cellulose/alizarin composite films can reach as high as 31 MPa, while UV-shielding performance and radical scavenging capacity were enhanced significantly with increasing the content of alizarin. Finally, the cellulose/alizarin films were successfully employed to monitor fish freshness as intelligent indicator films. Therefore, UV shielding, antioxidant and pH-responsive cellulose-based composite films incorporated with alizarin were manufactured successfully, which demonstrated great potentials to be used in intelligent packaging fields.

Biodegradable plastics are gaining popularity as environmentally friendly functional materials. This study focuses on the preparation of aluminum hydroxide (Al(OH) 3 ) reinforced cellulose acetate composite films using a cost-effective approach. The process involves synthesizing bamboo-derived cellulose acetate (BDCA), dissolving it in tetrahydrofuran with glycerol as a plasticizer, and incorporating Al(OH) 3 particles into the casting solution to reinforce the cellulose acetate film. Analyses on microstructure and characteristics of the films were conducted through various techniques, including scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, x-ray diffraction (XRD), water contact angle measurement, and tensile testing. The results indicate that the Al(OH) 3 particles were well-dispersed in the composite films, leading to a strong interaction with the cellulose acetate matrix. As a result, the prepared composite films exhibited significantly higher tensile strength compared to pure bamboo-derived cellulose film. Additionally, they demonstrated improved anti-ultraviolet properties and a lower water vapor transmission rate, despite being more hydrophilic. This method holds significant potential for commercial applications in producing high-performance cellulose acetate-based composite films. Highlights Bamboo-derived cellulose acetate was synthesized through chemical processes. BDCA based composite film reinforced with Al(OH) 3 was prepared by casting method. The Al(OH) 3 significantly enhance the functional properties of the composite film. Composite films showed good performances for packaging according to the results.

In recent years, conductive hydrogels have received increasing attention as wearable electronics due to the electrochemical properties of conductive polymers combined with the softness of hydrogels. However, conventional hydrogels are complicated to prepare, require high temperature or UV radiation to trigger monomer polymerization, and are frozen at low temperatures, which seriously hinder the application of flexible wearable devices. In this paper, a conductive sensor integrating mechanical properties, adhesion, UV shielding, anti-dehydration, and anti-freeze was prepared based on Ca2+-initiated radical polymerization at room temperature using the synergy of sodium lignosulfonate, acrylamide (AM), and calcium chloride (CaCl2). Metal ions can activate ammonium persulfate to generate free radicals that allow rapid gelation of AM monomers at room temperature without external stimuli. Due to ionic cross-linking and non-covalent interaction, the hydrogels have good tensile properties (1153% elongation and 168 kPa tensile strength), high toughness (758 KJ·m–3), excellent adhesive properties (48.5 kPa), high ionic conductivity (7.2 mS·cm–1), and UV resistance (94.4%). CaCl2 can inhibit ice nucleation, so that the hydrogels have anti-dehydration and frost resistance properties and even at −80 °C can maintain flexibility, high conductivity, and adhesion. Assembled into a flexible sensor, it can sense various large and small movements such as compression, bending, and talking, which is a flexible sensing material with wide application prospects.

Nowadays, new demands for improving living standards have posed novel challenges to traditional home textiles, and the development of nano-engineered functional textiles for improving indoor environmental quality has garnered considerable interest. However, the potential toxicity and poor fastness of nanoparticles have significantly impeded their applications in textiles. Herein, a facile strategy for synthesizing manganese dioxide (MnO 2 ) was presented through a hydrothermal method by using natural polysaccharides such as inulin, chitosan oligosaccharide, and alginate as reductants. The ‘one-stone-three-birds’ behaviors of natural polysaccharides were thoroughly explored, including reducing permanganate into MnO 2 , directing the assembly of nanoparticles, and ensuring their stability in aqueous solutions. Notably, inulin can efficiently regulate the synthesis of MnO 2 particles, and as-prepared MnO 2 exhibited distinct flower-like morphologies with higher crystallinity, rich surface adsorbed oxygen species, and encouraging ability of formaldehyde (HCHO) removal and antibacterial activity. Furthermore, without supplemental binder or catalyst, the multifunctional textile of C-MnO 2 was readily fabricated by simply immersing cotton fabric into MnO 2-Inu solution, and the obtained textile demonstrated satisfactory antibacterial performance under both dark and light irradiation conditions. Moreover, the obtained HCHO removal and UV-blocking properties were also encouraging. This inulin-dominated reduction and template synthesis of MnO 2 particles was first reported, and the presented technique of regulating particle synthesis and textile decoration paves the way for the application fields in multifunctional and sustainable home textiles.

To mitigate environmental impacts in food preservation, the development of a multifunctional membrane for packaging is of importance. In this study, we have successfully fabricated a nanofibrous membrane using an eco-friendly electrospinning technique, comprising polyvinyl alcohol (PVA), chitosan (CS), and tannic acid (TA). The resulting nanofibrous membranes were crosslinked with glutaraldehyde (GA) and surface modified with ZnO. Our findings demonstrate that the crosslinking process enhances water resistance, reduces water vapor permeability, improves tensile strength (from 3 to 18 MPa), and enhances thermal stability (increasing decomposition temperature from 225 °C to 310 °C). Furthermore, the incorporation of TA and ZnO provides antioxidant properties to the membrane, effectively preventing food decomposition caused by UV-induced oxidation. Additionally, CS, TA, and ZnO synergistically exhibit a remarkable antibacterial effect with a bacteriostasis rate exceeding 99.9 %. The strawberry fresh-keeping experiment further confirms that our developed membrane significantly extends shelf life by up to 6 days. Moreover, cytotoxicity assays confirm the non-toxic nature of these membranes. The innovative significance of this study lies in proposing a robust GA-PVA/CS/TA@ZnO nanofibrous membrane with excellent mechanical properties, biocompatibility, and multiple functionalities including antibacterial, anti-ultraviolet, and anti-oxidation capabilities. It has tremendous potential for applications in active food packaging materials.

The on-demand replacement of multifunctional hydrogel wound dressings helps to avoid bacterial colonization, and the on-demand painless peeling of tissue adhesive hydrogels on the wound site remains a major challenge to be solved. In this work, we design and develop a series of multifunctional dynamic Schiff base network hydrogels composed of cystamine-modified hyaluronic acid, benzaldehyde-functionalized poly(ethylene glycol)-co-poly(glycerol sebacate), and polydopamine@polypyrrole nanocomposite (PDA@PPy) with mild on-demand removability to enhance drug-resistant bacteria-infected wound healing. These hydrogels exhibited ideal injectable and self-healing properties, excellent tissue adhesion, in vivo hemostasis, good antioxidation, and conductivity. PDA@PPy inspired by melanin endows hydrogels with excellent antioxidant capacity, UV-blocking ability, and photothermal anti-infection ability. Based on the dynamic oxidation–reduction response of disulfide bonds inspired by the dissociation of the tertiary spatial structure transformation of poly-polypeptide chains, these hydrogels can achieve rapid painless on-demand removal under mild conditions by adding dithiothreitol. These multifunctional hydrogels significantly promoted collagen deposition and angiogenesis in the MRSA-infected full-thickness skin repair experiment. All the results showed that these multifunctional hydrogels with painless on-demand removal property showed great potential in clinical treatment of infected wounds.
