“…The addition of these NPs produces a uniform coating covering the entire fabric, as shown in Figure 4A (in contrast with the coating with only AgNPs), which contributes to the increase of all surface roughness, leading to higher WCA values. This finding is in agreement with several studies reporting the efficiency of ZnONPs to produce hydrophobic structures [6,11,48]. Therefore, the coating with ZnONPs significantly improves the hydrophobicity of the flax fabric, making it suitable for several applications, such as self-cleaning, easy-cleaning, and water-proof surfaces.…”

Cellulosic fibre-based smart materials exhibiting multiple capabilities are getting tremendous attention due to their wide application areas. In this work, multifunctional flax fabrics with piezoresistive response were developed through the combined functionalization with silver (Ag) and zinc oxide (ZnO) nanoparticles (NPs). Biodegradable polyethylene glycol (PEG) was used to produce AgNPs, whereas ZnONPs were synthetized via a simple and low-cost method. Flax fabrics with and without NPs were characterized by Ground State Diffuse Reflectance (GSDR), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectroscopy (EDS), X-ray Diffraction (XRD), Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR), and Thermogravimetric analysis (TGA). After creating a conductive surface by flax functionalization with AgNPs, ZnONPs were synthetized onto these fabrics. The developed fibrous systems exhibited piezoresistive response and the sensor sensitivity increased with the use of higher ZnO precursor concentrations (0.4 M). Functionalized fabrics exhibited excellent antibacterial activity against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria, higher hydrophobicity (WCA changed from 00 to >1000), UV radiation resistance, and wash durability. Overall, this work provides new insights regarding the bifunctionalization of flax fabrics with Ag/ZnO nanostructures and brings new findings about the combined effect of both NPs for the development of piezoresistive textile sensors with multifunctional properties.

“…With these results, it was also possible to conclude that the precursor concentration (zinc acetate) used in synthesis influenced the hydrophobic properties of the samples. Nevertheless, with exception of CCoF 0.2 , all the samples exhibited a hydrophobic behavior, being in agreement with several studies that report the efficiency of ZnO NPs to produce hydrophobic structures [43][44][45].…”

In the present work, 100% cotton knitted fabrics were functionalized with ZnO nanoparticles, in order to enhance the hydrophobic properties of the fibers surface. The incorporation methods of ZnO NPs and different types of cotton samples (including polymer coated, and uncoated with and without a nonionic pretreatment) were evaluated, in order to understand the influence in the hydrophobicity values. Cotton fabrics with and without NPs were characterized by ground-state diffuse reflectance, field emission scanning electron microscopy and energy-dispersive spectroscopy, attenuated total reflectance-Fourier transform infrared spectroscopy and water contact angle (WCA). The best results were obtained when the polymer-coated fabric was functionalized using a precursor concentration of 0.2 M, exhibiting superhydrophobic behavior with static WACs of more than 150°. Although pretreated and untreated ZnO-functionalized cotton fabrics had a slightly lower wettability, they showed interesting results, with improvements in WCA from 116° to 143°. In summary, this work demonstrates that the ZnO NPs have a huge potential to be used as surface finishings for the development of easy cleaning fibrous structures.

Plants remain the most important source in many industrial, medical, and agricultural applications, due to their production of many chemical compounds as represent secondary metabolites of plants, similar to those found in pharmaceutical compounds and chemical pesticides. The aim of this study was to determine the phytochemical separation of the leaves of the Myrtus communis L. extract plant by using the GC–Mass technique, and the role of these compounds as biological reducing agents in the green synthesis of zinc oxide nanoparticles. The analysis of GC–Mass showed the presence of many 11 chemical compounds, such as Eucalyptol, Vitamin E, Neophytadiene, and N-Methyl-1-adamantaneacetamide. The results also indicated the effectiveness of the identified compounds in the process of biosynthesis of zinc oxide nanoparticles, where the properties of the nanoparticles were described using UV-visible spectrophotometric and Field Emission Scanning Electron Microscope (FESEM), Where The peak of UV-Vis spectrophotometer was recorded at 366 nm, while the size and shape of ZnO NPs where average size was 30nm with roughly circular or spherical in shape. The research conclusion confirmed that the leaves of the M. communis L. extract plant contained many chemical compounds which have a role in the biosynthesis of ZnO NPs.
