Strong Antibacterial Properties of Cotton Fabrics Coated with Ceria Nanoparticles under High-Power Ultrasound

Abstract

Flexible materials, such as fabric, paper and plastic, with nanoscale particles that possess antimicrobial properties have a significant potential for the use in the healthcare sector and many other areas. The development of new antimicrobial coating formulations is an urgent topic, as such materials could reduce the risk of infection in hospitals and everyday life. To select the optimal composition, a comprehensive analysis that takes into account all the advantages and disadvantages in each specific case must be performed. In this study, we obtained an antimicrobial textile with a 100% suppression of E. coli on its surface. These CeO2 nanocoatings exhibit low toxicity, are easy to manufacture and have a high level of antimicrobial properties even at very low CeO2 concentrations. High-power ultrasonic treatment was used to coat the surface of cotton fabric with CeO2 nanoparticles.

Zinc Oxide Nanoparticles (ZnO NPs) and N-Methylol Dimethyl Phosphonopropion Amide (MDPA) System for Flame Retardant Cotton Fabrics

“…Nanomaterials in the form of nanoparticles are being used in the textile industry for antibacterial textiles [18], UV protection, increased flame retardancy, self-cleaning, electromagnetic shielding (EMI), conductive textiles, etc. [19][20][21]. Among the nanoparticles used in industry, metal oxides are of great importance because of their multipurpose properties [22].…”

Stearic Acid and CeO2 Nanoparticles Co-functionalized Cotton Fabric with Enhanced UV-Block, Self-Cleaning, Water-Repellent, and Antibacterial Properties

“…The bandgap of cerium oxide (3.1 eV) is less than those of titanium oxide (3.27 eV) and zinc oxide (3.37 eV); thus, it shows excellent ultraviolet absorbance ability with good photocatalytic activity. CeO 2 nanoparticles also have an inherent superhydrophobic character, demonstrating good application prospects as a superhydrophobic and UV-blocking material. , Previously, electrospun nanofibers of natural cotton cellulose have been functionalized with CeO 2 nanoparticles for UV protection and antibacterial activities; , however, their hydrophobic character has not been studied.…”

Adsorption of Different Pollutants by Using Microplastic with Different Influencing Factors and Mechanisms in Wastewater: A Review

“…Based on the principle of green environmental protection, waste utilization is the best way. Microplastics have been used to make electrospun micro/nanofibers (in the waste recycling) [12], PET nanoparticles (in the biological systems) [13], and antimicrobial coatings (in the healthcare sector) [14].…”
