“…Copper compounds such as cuprous oxide (Cu 2 O) and cupric oxide (CuO) are red and black, respectively [ 47 ]. According to Huang et al (2020), the contents of Cu 1+ and Cu 2+ on the surface of polyester fabrics coated with copper oxides affected their hue [ 48 ]. Therefore, the beige shade appearance of the fabric is due to the functionalization on an industrial scale (seen Figure 1 c) and may be related to the presence of copper oxide particles on its matrix and/or surface [ 22 , 48 ].…”

COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and healthcare-associated infections (HAIs) represent severe problems in health centers and public areas. Polyester/cotton (PES/CO) blend fabrics have been functionalized with copper oxides on an industrial scale. For functionalization, the impregnation dyeing technique was applied. The functionalized samples were tested virologically against SARS-CoV-2 and human coronavirus (229E) according to ISO 18184-2019 and microbiologically against Escherichia coli (ATCC 25922) bacteria according to ASTM E2149-2013. The results show that the fabric functionalized with copper oxides inactivated both viruses after 30 min of exposure, presenting excellent virucidal activity against 229E and SARS-CoV-2, respectively. Furthermore, its inactivation efficiency for SARS-CoV-2 was 99.93% and 99.96% in 30 min and 60 min exposure, respectively. The fabric inhibited bacterial growth by more than 99% before and after 10 and 20 washes. In conclusion, 265 m of PES/CO fabric (wide 1.7 m) was functionalized in situ on an industrial scale with copper oxide nanoparticles. The functionalized fabric presented virucidal and bactericidal properties against SARS-CoV-2 and Escherichia coli.

“…Fabric coloration can be fine-tuned by deposition of metallic thin films using magnetron sputtering. Due to the optical absorption edges of CuO and Cu 2 O, these thin films have proven useful for having a fabric set with a color palette [48,49].…”

The COVID-19 pandemic has further highlighted the need for antimicrobial surfaces, especially those used in a healthcare environment. Textiles are the most difficult surfaces to modify since their typical use is in direct human body contact and, consequently, some aspects need to be improved, such as wear time and filtration efficiency, antibacterial and anti-viral capacity, or hydrophobicity. To this end, several techniques can be used for the surface modification of tissues, being magnetron sputtering (MS) one of [hose that have been growing in the last years to meet the antimicrobial objective. The current state of the art available on textile functionalisation techniques, the improvements obtained by using MS, and the potential of diamond-like-carbon (DLC) coatings on fabrics for medical applications will be discussed in this review in order to contribute to a higher knowledge of functionalized textiles themes.

“…Recently, Huang et al obtained metallic color with copper (Cu) and copper oxides (Cu x O y ) film sputtered on polyester fabric by direct current magnetron sputtering with different sputtering currents, [ 31 ] as shown in Figure a. It could be seen that with the increase in sputtering current, the hue of copper‐coated fabrics changed from pale yellow to yellow, while the hue of copper oxide‐coated fabrics ranged from brown to dark red and then to dark green.…”

“…[ 7–10 ] By sputtering deposition of various materials onto textile substrates, the aforementioned functionalities have been mostly demonstrated in recently studies. [ 11–23 ] Specifically, the structural colors by interference, diffraction, and scattering of magnetron‐sputtered monolayer or multilayer films or the colors of sputtered films themselves can impart rich colors to textiles, [ 24–32 ] which may replace the conventional dyeing process without causing environmental pollution and health problems. Yet, most of reported progress was quite scattered, and a systematic understanding on the correlation of optical, color, and thermal management properties was still lacking.…”

The application of magnetron sputtering technology in the functionalization of textiles has attracted increasing attention owing to its green nature. The thin films deposited on textiles provide additional opportunities for precise control of solar and heat flows by tuning the optical properties. In this review, the principles of color regulation, thermal management (including photothermal conversion and reflective insulation) properties, and simultaneous color and thermal management of sputtered thin films based on their interaction with solar radiation (visible and near‐infrared light) and thermal radiation are briefly summarized, and their research progress in textile coloring and thermal management as well as thermal management of colored textiles is reviewed. In addition, the challenging and future research of sputtered films on textiles for coloring and thermal management is briefly presented.
