“…This technology is easy to implement and makes it possible to control the microstructure of both thin films and the properties of gels themselves. There are methods used to create titanium dioxide thin films, such as sputtering [ 15 ], ion beam deposition [ 16 ], and hydrothermal processes [ 17 ], but the sol–gel deposition process has a lower cost and is technologically simple, flexible, and easily scalable [ 18 , 19 ].…”

A promising approach that uses the sol–gel method to manufacture new breathable active films with self-cleaning and antibacterial surfaces is based on the PET membranes obtained via ion track technology with a pore density of 10–7 cm−2 and a pore diameter of about 500 ± 15 nm, coated with a layer of TiO2 anatase, with a thickness of up to 80 nm. The formation of the photocatalytically active TiO2 anatase phase was confirmed using Raman analysis. Coating the PET membrane with a layer of TiO2 increased the hydrophobicity of the system (CA increased from 64.2 to 92.4, and the antibacterial activity was evaluated using Escherichia coli and Staphylococcus aureus bacteria with the logarithmic reduction factors of 3.34 and 4.24, respectively).

A Cu-TiO 2 nanomaterial with unique antibacterial and photocatalytic properties is introduced in this study. Cu-TiO 2 nanocomposites were obtained using an adapted direct current magnetron sputtering apparatus, where TiO 2 anatase nanoparticles (NPs) were used as the substrates and copper as the sputtering target. The obtained powder was characterized by physical and chemical methods. Copper was deposited on TiO 2 NPs for 30 and 60 min, resulting in two samples with different copper contents of 3 and 5 wt %, respectively. The photocatalysis test evaluated the degradation of rhodamine B (RhB) dye under a specific wavelength (405 nm LED) and a complete degeneration occurred in 120 min, ∼ 33% faster when compared to pristine TiO 2 . The antibacterial assays were performed for Escherichia coli and Staphylococcus aureus in dark and visible-light conditions, using a 405 nm LED and a wide-spectrum white LED, reaching an inactivation of 99.9999% for both bacteria. The magnetron sputtering is an ecofriendly way to form heterojunctions with photocatalytic and bactericidal properties in the absence of wet chemical methods or residues. This work may open new pathways for enhancing the fungicidal and virucidal activities of nanocomposites under the action of visible light.
