“…As shown in Figure 2a, the characteristic peak of -N═C═O (2264 cm −1 ) in IPTS spectrum disappeared and new peaks corresponding to the -NH-C═O-(1702 and 1533 cm −1 ) appeared in QAS 18 spectrum. [31] Furthermore, the absorption peaks of -CH 3 (2920 cm −1 ) and -CH 2 (2850 cm −1 ) were observed in QAS 18 spectrum, which were ascribed to the introduction of long chain alkyl groups. Comparing with ZnO, the peaks of -CH 3 (2920 cm −1 ), -CH 2 (2850 cm −1 ), C═O (1702 cm −1 ) in ZnO-QAS 18 spectrum (Figure 2b) were detected.…”

“…Siloxane quaternary ammonium monomer was synthesized according to a reported literature with modification. [31] The synthesis procedure was shown in Figure 1I. Briefly, 1.78 g of DMEA, 5.94 g of IPTS, and 0.5 g of DBDU were dissolved in 100 mL of N, N-dimethylformamide (DMF) with continuous stirring and refluxing at 90 °C under nitrogen atmosphere.…”

Wound dressings are usually employed to maintain suitable conditions around the injured skin to accelerate wound healing. This paper aims to report functional composite dressings combined with polycaprolactone (PCL) nanofibers, self-assembly zein coating and modified ZnO nanoparticles (ZnO NPs) for wound management. The synthetic compounds and prepared composite dressings are characterized by Fourier infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy. Meanwhile, the water vapor transmission rate, hemostatic performance, antibacterial activity, and cytocompatibility of the composite dressings are systematically tested to evaluate their applicability in wound treatment. The results show that the multilayer dressings can retain moisture and prevent excessive dehydration of wound. In vitro hemostatic test is conducted, and the enhanced blood clotting capacity and the activation of platelets indicate that the desired dressings are able to control hemorrhaging from wound. Meanwhile, the composite dressings with excellent biocidal efficacy against Gram-positive Staphylococcus aureus (6.01 Log within 30 min) and Gram-negative Escherichia coli O157:H7 (6.04 Log within 30 min) can effectively prevent wound infection. Furthermore, the dressings show no toxicity which are evidenced in hemolysis and cytocompatibility evaluation, and have potential application for wound healing.

“…Chlorine loading of the active chlorine content of samples was determined by iodometric titration, which is widely used in the preliminary determination of the antibacterial properties of fabrics [40,41]. Briefly, 0.15 g of the treated fabrics were cut into pieces and then added into a beaker with 15 ml deionized water and 0.1 g KI.…”

Antibacterial textile materials are widely used in daily life, but most are disposable products with poor antibacterial durability. N-halamine can rapidly inactivate microorganisms, has good stability, and shows great potential applications in antibacterial fabrics. In this study, an N-halamine monomer precursor was synthesized and treated onto PET fabrics. The treated PET fabrics were rendered antibacterial functionality after chlorination, and exhibited good antibacterial properties with inactivation rate of 100.0 % for both E. coli O157:H7 and S. aureus. After 50 wash cycles, the chlorinated treated PET fabrics could maintain 80.0 % antibacterial efficacy, demonstrating durable antibacterial properties. Storage stability and UV irradiation tests showed that the treated PET fabrics had remarkable regenerable properties. The reduction of the breaking strength was within 12 % after treatment, which is in a satisfying range in antimicrobial finishing.

The application of solar-driven interface evaporation photothermal materials in the complex water environment is facing great challenges, and the development of multifunctional photothermal materials is great significance to the practical application process. In this study, a new kind of photothermal material was first prepared based on the natural pumices, which shows great advantages of lightweight, superhydrophilicity, porous property, and heat insulation. To improve its light absorption capacity and photocatalytic effect, carbon and Ag + were uniformly loaded on pumices (named P-C-Ag + ). The as-resulted P-C-Ag + shows an evaporation rate of 1.395 kg m À2 h À1 which refers to an evaporation efficiency of 88.80% in simulated seawater under 1 kW m À2 illumination. In the rooftop experiment, the cumulative evaporation capacity of the simulated solar evaporator with P-C-Ag + in 8 hours can reach about 7.25 kg m À2 . Meanwhile, almost no salt crystallization was found in the surface of P-C-Ag + during the continuous evaporation process. The P-C-Ag + has a good inhibitory effect on Escherichia coli and algae, and can degrade color dyes, which is also beneficial to water environment, thus holding great potential as multifunctional photothermal material for solar steam generation and water treatment.
