Durable antibacterial and UV-protective Ag/TiO₂@fabrics for sustainable biomedical application

ZnO and TiO2 Nanoparticles as Textile Protecting Agents against UV Radiation: A Review

“…It was found that using optimum concentrations of CA (30gm/l) with (SHP)(18gm/l) and TiO 2 NPs (0.5gm/l) resulted in higher flame retardancy effect, lower pilling formation, improved antibacterial activity against S. aureus bacteria and increasing hydrophilicity, photocatalytic activity, self-cleaning property and wash fastness of treated fabrics. Also, optimum conditions caused slight decrease in tensile strength but after exposure to UV radiation there was an improvement in fabrics tensile strength due to the effect of TiO [37].…”

Nanocomposite and biodegradable polymers applied to technical textiles

“…Another category is the special or functional polymers obtained by modification of existing polymers, or polymers that contain an improved degree of functionality. This is the case of polymeric compounds that can absorb ultraviolet radiation and be available as a coating, some incorporate nanoparticles such as zinc oxide (ZnO) [52,53], titanium dioxide (TiO2) [54], between others. Also, polymeric compounds of polylactic acid with carbon nanotubes (CNT) for electromagnetic interference shields [55].…”

“…Source: The Authors. offer great promise in applications of large-scale energy storage devices [54]. Likewise, Fan et al [65] obtained about 10 S/cm electrical conductivities from graphene oxide (GO) compounds with polyaniline, optimizing the method of preparation and exfoliation in the synthesis of GO.…”

Recent advances in the ultraviolet protection finishing of textiles

“…When applying inorganic UV blockers to textile substrates, researchers have faced several problems associated with the agglomeration of NPs, low adsorption ability of textile fi bres for NPs and low durability of the coating. To resolve these problems, new routes of synthesis of NPs have been introduced to improve the dispersity of NPs, such as the in situ growth of NPs on textile fi bres in the presence of stabilising agents [31, [46][47][48]; and the use of hydrothermal, solvothermal, microwave and sputtering deposition methods [32,45,[49][50][51][52][53][54]. To enhance the adsorption ability of textile fi bres and consequently the washing durability of the coatings, plasma treatments have been used to increase the textile wettability and the surface roughness [54][55][56], polyester fi -bres have been pre-treated with sodium hydroxide to improve their wettability [57,58] and cellulose fi bres have been pre-modifi ed with chloroacetic acid to create new active carboxylic groups [31].…”

“…Simultaneous UV blocking properties and antimicrobial and self-cleaning activities were generated for protective clothing, sportswear and medical textiles. To this end, Ag was used in combination with TiO 2 and applied to cellulose fibres by diff erent application processes [50,52,[59][60][61]. Commercial Ag/TiO 2 nanocomposites were applied to cotton fabric during the exhaustion dyeing process to simultaneously load Ag/ TiO 2 and reactive dye on cotton [59].…”
