“…To create antimicrobial textiles, cellulose fibers represent the most attractive textile substrate for the application of ZnO Ps [11,32,42,66,68,69,72,73,76,82,[84][85][86]88,90,[122][123][124][125][126][127]. In addition to cellulose, ZnO Ps have been applied to different synthetic fibers, such as polyester [16,99,100,128], polypropylene [15,99,129], polyamide [99], polyurethane [109] and cellulose/polyester blends [14,94].…”

“…Another important advantage of the in situ synthesis of ZnO NPs is the good adhesion between NPs and textile substrates, which consequently improves the durability of UV protection. For human skin protection against UV irradiation, ZnO has mostly been applied to woven and knitted cotton fabrics, since natural cellulose fibers are usually used for the tailoring of light summer protective clothing [11,[71][72][73]77,78,80,83,84,[86][87][88][90][91][92]. Research on other textile substrates has been presented as well [106,110,129].…”

“…Since this property is strongly dependent on structure and morphology, only ZnO grown on textile substrates in the form of a one-dimensional wurtzite nanocrystal structure, such as nanorods (NRs) and nanowires (NWs), can create a transparent conductive network with excellent electrical conductivity, low sheet resistance, and mechanical flexibility (Figure 12) [98,[146][147][148][149]. To synthesize the ZnO NR array layer in situ on the surface of textile fibers, solvothermal [89], hydrothermal [98], ultrasonic irradiation [10], sol-gel [90,95], spin-coating [150], electro-deposition [9,111], and atomic layer deposition [93] methods were recently used. piezoelectric and semiconducting properties of the ZnO NRs enabled the textile substrates to harvest mechanical energy from human bodies and act as the mechanical sensing and monitoring devices ( Figure 13).…”

The use of ZnO for the functionalization of textile substrates is growing rapidly, since it can provide unique multifunctional properties, such as photocatalytic self-cleaning, antimicrobial activity, UV protection, flame retardancy, thermal insulation and moisture management, hydrophobicity, and electrical conductivity. This paper aims to review the recent progress in the fabrication of ZnO-functionalized textiles, with an emphasis on understanding the specificity and mechanisms of ZnO action that impart individual properties to the textile fibers. The most common synthesis and application processes of ZnO to textile substrates are summarized. The influence of ZnO concentration, particle size and shape on ZnO functionality is presented. The importance of doping and coupling procedures to enhance ZnO performance is highlighted. The need to use binding and seeding agents to increase the durability of ZnO coatings is expressed. In addition to functional properties, the cytotoxicity of ZnO coatings is also discussed. Future directions in the use of ZnO for textile functionalization are identified as well.

“…In an interesting study, cotton fabrics were also used as gas sensors. Untreated and ZnO NP-added cotton fabrics were used to sense 100 ppm of acetaldehyde and other interfering gases at 25 • C [66]. An improved acetaldehyde response was obtained for ZnO-modified cotton fabric owing to the homogeneous distribution of ZnO NPs and the presence of high porosities between the inter-yarn pores.…”

Volatile organic compounds (VOCs) are among the most abundant air pollutants. Their high concentrations can adversely affect the human body, and therefore, early detection of VOCs is of outmost importance. Among the different VOCs, in this review paper we have focused our attention to the monitoring of acetaldehyde by chemiresistive gas sensors fabricated from nanostructured semiconducting metal oxides. These sensors can not only provide a high sensing signal for detection of acetaldehyde but also high thermal and mechanical stability along with a low price. This review paper is divided into three major sections. First, we will introduce acetaldehyde as an important VOC and the importance of its detection. Then, the fundamentals of chemiresistive gas sensors will be briefly presented, and in the last section, a survey of the literature on acetaldehyde gas sensors will be presented. The working mechanism of acetaldehyde sensors, their structures, and configurations are reviewed. Finally, the future development outlook and potential applications are discussed, giving a complete panoramic view for researchers working and interested in acetaldehyde detection for different purposes in many fundamental and applicative fields.

Then, the fundamentals of chemiresistive gas sensors will be briefly presented and, in the last section, a survey of literature on acetaldehyde gas sensors will be discussed. Acetaldehyde sensors working mechanism, their structures and configurations are reviewed. Finally, the future development outlook and potential applications are discussed, giving a complete panoramic view for researcher working and interested in acetaldehyde detection for different purposes in many fundamentals and applicative fields.
