“…[4,5] However, the response range to visible light of ZnO nanoparticles is narrow and the photogenerated electrons and holes are prone to recombination easily, which have restricted the application of pure ZnO in actual application extremely. [6] Up to date, the noble metal [7][8][9][10] and other nanoparticles with narrow band gap such CdS, [11] V 2 O 5, [12] Bi 2 O 3, [13] C 3 N 4 [14,15] ZnO nanomaterials to improve its photo response range to visible light. [16] But it should not to be ignored that although these nanomaterials can improve the photocatalytic activity of ZnO, but their high cost or potential heavy metals pollution restricts their applications.…”

Zinc oxide@carbon quantum dots (ZnO@CQDs) nanocomposite was prepared via a facile hydrothermal method. Characterization of the obtained samples was carried out by Scanning electron microscopy-EDX(SEM-EDX), Transmission electron microscopy (TEM), X-ray diffraction (XRD), Photoluminescence (PL), and Fourier transformed infrared spectroscopy (FT-IR). These results revealed that we have prepared ZnO@CQDs nanocomposite successfully. Our study revealed that the antibacterial efficiency (against S.aureus and E.coli) under visible light irradiation of as prepared ZnO@CQDs nanocomposite was higher than pure ZnO nanoparticles. The ZnO@CQDs nanocomposite showed excellent antibacterial activity against Gram-negative and Gram-positive bacteria with a minimal inhibitory concentration (6-8 mg/mL) against to E.coli and S.aureus. We also tested the light response of ZnO@CQDs under UV-vis light, by calculating its band gap data, after decorated with CQDs, the band gap of the pure ZnO can significantly decreased from 2.57 eV to 2.50 eV. The ZnO decorated by CQDs can both enhance the light absorption and suppress photogenerated electron-hole's recombination which results in the enhancement of antibacterial properties.

This study demonstrates the synthesis of nano-zinc stannate and its application as a novel multifunctional finishing agent on cotton fabric. Nano-zinc stannate has been synthesized by the co-precipitation method, and the nanostructures produced have been characterized to investigate their morphology and microstructure by using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction techniques. The synthesized nano-zinc stannate has been applied on cotton fabric and the multifunctional efficacies of the treated fabric, like UV resistance, antibacterial property, self-cleaning, as well as thermal stability, were analyzed. The as-synthesized zinc stannate-treated cotton fabric showed excellent efficiency in self-cleaning, antibacterial property, and flame-resistant action compared to the annealed nano-zinc stannate-treated cotton fabric. It was observed that the ultraviolet protection factor of the treated (annealed zinc stannate-treated) fabric shoot up more than 45 after treatment, and the same fabric showed more than 90% bacterial resistance against both Gram-positive and Gram-negative bacteria. Concerning thermal kinetics, the as-synthesized zinc stannate-treated fabric registered a 39% reduction in the peak heat release rate compared to the untreated cotton fabric, and it also showed catalyzed pyrolysis action and more amount of char mass (30–40% more compared to the control cotton) formation at higher temperature. The self-cleaning efficacy of the treated fabric has been examined against coffee stain and basic methylene blue dye. The treated fabric exhibited a good efficiency in cleaning of stain due to the free-radical scavenging behavior. Finally, it also has been proved that the integration of these nanostructure did not have any detrimental effect on the important physical properties (tensile strength, flexibility, and crease resistance) of the treated fabric.

“…To avoid these limitations, cotton fabrics have been treated for enhanced hydrophobicity and antibacterial activity [15–19]. The surface of cotton fabrics has been reported to functionalize with Ce doped ZnO nanorods to enhance UV resistance and antibacterial activity [20]. The combined hydrophobicity and antibacterial activity have been achieved on fabrics treated with Cu nanoparticles doped silica-based sols [21].…”

Inducing multifunctionality is the need of the products used in diverse environments. Here, polyurethane-based water repellent, flame retardant and antibacterial coatings are fabricated on cotton fabrics which sequentially involve the deposition of coating through knife coating, drying and curing of coated fabric. Taguchi design has been used to optimize the parameters for enhanced water repellency, flame retardancy and antibacterial activity. When applied individually, the performance characteristics enhance with the increase in concentration of respective finishing agent. However, a different behaviour was shown by the coated fabric when applied all the finishing agents simultaneously. Taguchi design enabled the monitoring of interdependency of different concentrations of chemicals and finding the most influencing parameters for efficient performance of coated fabrics.
