“…The self-cleaning activity of ZnO Ps has mostly been studied on ZnO surface-modified cotton [13,107,114,118] and polyester [101,105,115] fibers, as well as cotton/polyester blends [94]. As stains, coffee, tea, and the dyes methylene blue and rhodamine B were applied to the textile fabric surface before exposure to solar and UV light irradiation for different intervals under different humidity conditions.…”

“…The results showed that the self-cleaning properties depended on the content of ZnO Ps. A higher concentration of ZnO Ps resulted in increased photocatalytic degradation [94,105,115,118]. A treatment of polyester with sodium hydroxide to increase the surface area and wettability of fibers enhanced the adsorption of ZnO Ps and consequently the self-cleaning degradation of methylene blue [101,107].…”

“…Furthermore, the photocatalytic activity of ZnO was enhanced when coupled with other semiconductors or carbon materials [94,118]. Accordingly, if Fe 3 O 4 /ZnO nanocomposites were deposited on a cotton/polyester fabric, an increase in the self-cleaning properties of the sample was obtained with an increase in the concentration of iron sulphate [94]. It was believed that the presence of Fe 3 O 4 increased the possibility of the separation of photo-generated charges, prolonging the electron-hole recombination.…”

“…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].…”

“…The antibacterial activity of textile fibers has been most often tested against Staphylococcus aureus Gram-positive bacteria [14][15][16]42,67,68,72,75,76,82,94,99,126,127,129] and Escherichia coli Gram-negative bacteria [15,16,42,67,68,76,94,99,109,124,126,127,129]. In addition, testing against methicillin-resistant Staphylococcus aureus (MRSA) [82], Staphylococcus epidermidis [82], Propionibacterium acnes [82], Candida albicans [16,42,94,124], Bacillus subtilis [67], Pseudomonas aeruginosa [67], Saccharomyces cerevisiae [125], Gluconobacter cerinus [88], and Klebsiella pneumonia [72] has been performed. The antifungal activity has been tested against Aspergillus flavus [126].…”

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.

To recycle powdered photocatalysts and make full use of their active sites, one efficient way is to load these particles on the supporting materials. It is demonstrated that the supports are beneficial because they adsorb organic pollutants to be degraded. However, the effect of the supports on the energy band structure of the generated composite photocatalysts remains unclear. In this study, a heterojunction composed of graphitic carbon nitride (g-C 3 N 4 ) and TiO 2 (g-C 3 N 4 -TiO 2 ) was constructed and simultaneously immobilized on the surface of cotton fibers in a one-step hydrothermal process. The structural characteristics and photocatalytic performance of the g-C 3 N 4 -TiO 2 modified cotton fibers (C-g-C 3 N 4 -TiO 2 ) were systematically examined. It was found that g-C 3 N 4 nanosheets were combined with assynthesized TiO 2 nanoparticles during the hydrothermal reaction to form an intimate heterojunction, which was chemically grafted onto cotton fibers via C/O-Ti 4? /Ti 3? bonds. Meanwhile, TiO 2 nanoparticles were introduced into the swollen cotton fibers. Most notably, the cellulosic cotton substrates could increase the energy band gap of g-C 3 N 4 -TiO 2 nanocomposites, as demonstrated by the density functional theory (DFT) calculations. The reaction order of radical species (ÁO 2) did not change during MO photodegradation no matter whether the g-C 3 N 4 -TiO 2 was loaded on cotton fibers. The selfcleaning experiments showed that g-C 3 N 4 -TiO 2 modified cotton fabrics could be repeatedly used to remove organic contaminants.
