“…In this study, it is found that the Ti-3wt%Cu alloys under different conditions exhibit excellent antibacterial ability ([ 95%) according to our antibacterial evaluation results, which is an significant improvement compared with previous reports on the Ti-3wt%Cu alloy without rolling and annealing [28,29]. The antibacterial mechanism of Cubearing phase is not yet fully revealed; however, possible mechanisms such as nucleic acids and lipids, oxidation of cell proteins, inhibition of biofilm, damaging DNA and various essential cell reactions have been proposed [30][31][32][33][34][35]. According to theses mechanisms, the improved antibacterial ability can be resulted from increasing effective contact, which can inhibit bacteria adhesion on the surface and avoid the formation of bacterial biofilm [36].…”

In this work, a process of cold rolling with 70% thickness reduction and different annealing temperatures was selected to regulate the microstructure of Ti-3wt%Cu alloy. Microstructural evolution, mechanical properties and antibacterial properties of the Ti-3wt%Cu alloy under different conditions were systematically investigated in terms of X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), tensile and antibacterial test. The results indicated that cold rolling could dramatically increase the ultimate tensile stress (UTS) from 520 to 928 MPa, but reduce the fracture strain from 15.3% to 3.8%. With the annealing temperature increasing from 400 to 800 °C for 1 h, the UTS decreased from 744 to 506 MPa and the fracture strain increased from12.7% to 24.4%. Moreover, the antibacterial properties of the Ti-3wt%Cu alloy under different conditions showed excellent antibacterial rate ([ 96.69%). The results also indicated that the excellent combination of strength and ductility of the Ti-3wt%Cu alloy with cold rolling and following annealing could be achieved in a trade-off by tuning the size and distribution of Ti 2 Cu phase, which could increase the applicability of the alloy in clinical practice. More importantly, the antibacterial properties maintained a good stability for the Ti-3wt%Cu alloy under different conditions. The excellent combination of mechanical properties and antibacterial properties could make the Ti-3wt%Cu alloy a good candidate for long-term orthopaedic implant application.

“…The FDA has sanctioned TiO 2 ’s use in various consumer products, including food and cosmetics [ 85 ]. It can be directly applied as a TiO 2 film on steel or incorporated as an antibacterial agent in polymer coatings [ 106 , 107 , 109 , 110 , 111 , 112 , 113 , 114 ]. Hung and Yemmireddy have evaluated the durability of antimicrobial coatings for food-contact surfaces [ 115 ].…”

This article will focus on the issue of protection against the pathogenic biofilm development on steel surfaces within the food sectors, highlighting steel’s prominence as a material choice in these areas. Pathogenic microorganism-based biofilms present significant health hazards in the food industry. Current scientific research offers a variety of solutions to the problem of protecting metal surfaces in contact with food from the growth of pathogenic microorganisms. One promising strategy to prevent bacterial growth involves applying a polymeric layer to metal surfaces, which can function as either an antiadhesive barrier or a bactericidal agent. Thus, the review aims to thoroughly examine the application of antibacterial polymer coatings on steel, a key material in contact with food, summarizing research advancements in this field. The investigation into polymer antibacterial coatings is organized into three primary categories: antimicrobial agent-releasing coatings, contact-based antimicrobial coatings, and antifouling coatings. Antibacterial properties of the studied types of coatings are determined not only by their composition, but also by the methods for applying them to metal and coating surfaces. A review of the current literature indicates that coatings based on polymers substantially enhance the antibacterial properties of metallic surfaces. Furthermore, these coatings contribute additional benefits including improved corrosion resistance, enhanced aesthetic appeal, and the provision of unique design elements.

“…They have exceptional hydrophobic properties where epoxy was utilised for this purpose. It has been observed that the introduction of nano-fillers such as TiO2 can result in superhydrophobic Nanocoatings with unique combined properties such as anti-corrosion, anti-bacterial, anti-icing, antifogging, self-cleaning, and anti-fouling properties [113].…”

The automotive industry is a rapidly growing sector of the economy of most countries. Due to consumer and world population growth, the continuous necessity of a better, safe, and economical transportation approach increases with low emission. Researchers and producers face many challenges in the automobile industry for environmental issues, greenhouse gas emissions, boosting the fuel economy, weight minimization, and maintaining modern automobiles’ safety and performance. Several strategies towards developing innovative materials have been introduced to address the challenges and replace heavy metal with lightweight polymer composite. Lightweight polymer composite materials offer great potential for increasing vehicle efficiency, decreased fuel consumption, reduced vehicle weight, and corrosion avoidance perspective than heavier materials. Epoxy as a thermoset polymer added with filler material produces nanocomposite material, which increased mechanical, chemical, electrical, and thermal properties, high compatibility, low cost, and shrinkage played significant roles in this regard. This article summarises the material selection process and the application of lightweight polymer composite materials, especially epoxy nanocomposite material, in the automotive industry.
