“…New challenges and demands, however, are being encountered, and the need for surfaces with functional characteristics is becoming increasingly frequent [8][9][10]. Surface modification becomes one of the strategies that should be investigated, with the objective, for example, of preventing or reducing bacterial adhesion [11][12][13][14][15][16]. Surfaces can be modified by physical or chemical processes [4,8,11].…”

“…Examples of the chemical approach include the pre-incorporation of pharmacologically active bactericidal agents, such as antibiotics, antiseptics, metallic ions, or other organic and inorganic substances. The literature reports physical strategies that involve the use of metals based on silver or copper [12]. This is not the only strategy, however; aluminum/TiO 2 coatings reported in the literature show promising results, as they promote photocatalytic antibacterial effects, together with scratch-resistant and self-cleaning characteristics [17].…”

TiN-Ag ceramic coatings deposited by magnetron sputtering on silicon wafers and AISI F138 stainless-steel substrates with different Ag concentrations were evaluated for their application as decorative coatings. The results obtained indicated an almost linear increase in the thickness and roughness of the film as a function of the increase in the silver content of the film. For Ag concentrations greater than (8.3 ± 0.5) at %, a matte/satin finish was observed, i.e., a dull surface, produced by the agglomeration of particulates and the increase in roughness, respectively, which was corroborated by SEM and AFM analyses. The EDS analyses indicated particles with a high concentration of silver, but the elements titanium and nitrogen were also observed, indicating the formation of the TiN-Ag coating. The L*a*b* parameters in the CIELab color space were evaluated. No major variations were observed for coatings A and B (Ag concentrations of (4.1 ± 0.4) and (6.3 ± 1.2) at %, respectively). When the Ag content increased substantially, there was a corresponding decrease in L* values, as well as a shift in red reflectance. Furthermore, unwanted changes in the visual appearance and resistance to accelerated corrosion (salt spray) were also analyzed, as these factors compromised the film’s aesthetics in decorative applications.

An Assessment of the Bactericidal and Virucidal Properties of ZrN-Cu Nanostructured Coatings Deposited by an Industrial PVD System

Pathogenic microbes, such as bacteria and viruses, can spread quickly via contaminated surfaces. Most of these pathogenic microorganisms can survive on surfaces for a long time. Touching these surfaces can lead to the transmission of the microorganisms to the human body and cause serious illnesses. ZrN-Cu coatings containing different amounts of Cu were deposited using an industrial PVD system, and their ability to inhibit bacteria and inactivate the SARS-CoV-2 virus was tested. Microstructural studies showed the formation of two distinct ZrN and Cu phases when Cu content was sufficiently high. Hardness and elastic modulus were inversely proportional to the Cu content. The coatings showed outstanding bactericidal properties against Escherichia coli and Pseudomonas aeruginosa, especially when Cu content was more than 12 at.% and exposure time was longer than 40 min. The coatings, however, did not exhibit any significant virucidal properties. Good mechanical properties, along with excellent antibacterial effects, make these coatings suitable for use as self-sanitizing surfaces on objects that people regularly touch and that are prone to bacterial contamination. Their use would thus allow for only minimal transmission or multiplication of bacteria, and the treated surface would not serve as another source of infection.

Laser treatment is a high-efficiency coating process with many advantages of stable performance, convenient operation and environmental friendly. In this study, an efficient method for the pretreatment of polyester fabric, based on exposure to the output from a CO2 laser, is investigated. Polyester fabrics were treated by laser and then copper films were coated on the surface of treated polyester fabrics by magnetron sputtering method. Copper-coated polyester fabrics were characterized by XRD and SEM. Contact angle, heat generation and electrical conductivity of copper coated polyester fabric were tested. The electrical conductivity, UPF value and contact angle of copper-coated polyester fabric with pretreatment of 6.5 W lasers are 0.239 Ω/sq, 147.4, and 128.5°, respectively. The temperature of copper-coated fabric can be kept at 25.8℃ using only 5 V. The results suggest that the copper-coated polyester fabric with pretreatment of laser has excellent electrical conductive property, hydrophobicity, UV blocking, and heat generation properties. The adhesion strength between copper coating and fibers is improved after laser treatment. Laser can be potentially used in pretreatment of fabrics before coating in the future.
