Antibacterial and ultraviolet protective neodymium-doped TiO₂ film coated on polypropylene nonwoven fabric via a sputtering method

Abstract

A neodymium-doped titanium dioxide film was coated on polypropylene nonwoven fabric via a magnetron sputtering method to prepare multifunctional textiles with antibacterial and ultraviolet protective properties. The antibacterial property of the single-layer titanium dioxide film coated sample was better than that of the single-layer neodymium film coated sample. And that of the three-layer film coated samples was better than that of the double-layer film coated samples, which the latter also was superior to that of the single-layer film coated samples. A longer deposition time of the titanium dioxide film increased the antibacterial rate. The hydrophilicity of the coated samples was improved by ultraviolet irradiation, which improves the catalytic antibacterial ability. The ultraviolet protective factor of the sample that absorbs more ultraviolet is higher, and the water contact angle after ultraviolet irradiation decreases. This improves antibacterial performance. A titanium dioxide film doped with neodymium was improved without any significant change to the morphology and luster of the samples. This can lead to further applications of the coated polypropylene non-woven fabric with good antibacterial properties.

Structural colouration on textile fabrics with thin-film coating via magnetron sputtering: A review

“…Ag/TiO 2 bilayer thin films Silver demonstrates outstanding electrical and optical properties, whereas TiO 2 exhibits a high photocatalytic activity and good chemical stability in addition to being environmentally friendly. The use of these materials to create functional fabrics has been the subject of numerous studies [13][14][15][16]18,[45][46][47][48][49]. Additionally, materials can be coated with these two substances to impart a structural colour.…”

Photocatalytic Biocidal Coatings Featuring Zr6Ti4-Based Metal–Organic Frameworks

“…Infectious pathogens such as drug-resistant bacteria and viruses, including SARS-CoV-2, comprise serious public safety concerns worldwide and can significantly disrupt global commerce and human health. − The development of safeguards against these biological threats is imperative; however, the sporadic nature of breakout events and the threat of new diseases that arise from novel microorganisms complicate the development of protective technologies. − One important mode of transmission for these pathogens is through contaminated clothing and textiles as it has been shown that pathogens can survive on cloth for several days, increasing the likelihood of spreading disease. − In light of this challenge, the biocidal treatment of cloth materials represents a promising strategy to decrease microbial contamination and reduce the spread of infection. ,− …”
