“…The new materials showed high stability and antibacterial effectiveness even after intensive laundry regimes are employed in hospitals 2,3 . Recently some inorganic metal oxides [4][5][6][7][8][9][10] and metals nanoparticles coated cotton composites have attracted attention, due to significant antimicrobial activities against pathogenic bacteria [11][12][13][14] . Alternative inorganic nanocomposite materials have gained interest due to their safety and selective toxicity against bacteria 10,[15][16][17][18][19] .…”

ZnO-NPs coated cotton or starched cotton fibers were successfully prepared via ultrasound irradiation. Different concentrations of soluble corn starch (1-3 starch wt.%) were used to stabilize ZnO-NPs onto the surface of cotton fabrics as entrapped species. the use of none-toxic biocompatible starch has improved the adhesion properties of the cotton fibers towards ZnO-NPs. This also enhanced the durability of Zno-nps onto the cotton fabrics and decreased their leaching from the surface of cotton fabrics. When 3 starch wt.% solution was used, deposition of ZnO-NP increased by 53% after 10 washing cycles. the antibacterial activity against Staphylococcus aureus and escherichia coli increased by 50 and 21.5%, respectively. Functionalization of ZnO coated cotton with silver nanoparticles (Agnps) and curcumin results in formation of Zno-Ag/cotton and Zn(ii) curcumin/cotton composites. the functionalized nanocomposites Zno-Ag coated cotton material showed a synergistic antimicrobial behavior than that of individual Zno/cotton material. the Zn(ii) curcumin complex coated cotton showed higher antibacterial activities against both Staphylococcus aureus (Gram-positive) and escherichia coli (Gram-negative) bacteria than that of the Zno/cotton material.

“…For example, antibacterial textiles were produced by incorporating AgNPs into cotton fabrics. It was found that the AgNP-embedded cotton fabrics could withstand 30–50 sequent laundering cycles without losing their antibacterial effect against S. aureus and E. coli [ 11 ].…”

Silver nanoparticles (AgNPs) are widely used as antibacterial agents, but their antibacterial durability and the influence by storage conditions have not been thoroughly investigated. In this study, AgNPs were produced using a picosecond laser and stored under three different conditions: daylight, dark and cold (4 °C). The antibacterial effects of the laser AgNPs were examined against Escherichia coli in either a 14-day interval (frequent air exposure) or a 45-day interval (less frequent air exposure) using a well-diffusion method until the antibacterial effects disappeared. Results showed that the antibacterial activity of the laser generated AgNPs lasted 266 to 405 days. Frequent air exposure increased particle oxidation as measured by high-angle annular dark-field detector for scanning transmission electron microscopy (HAADF-STEM) and X-ray energy dispersive (EDX) spectroscopy, and reduced the antibacterial duration by about 13 weeks. Compared to the chemically produced AgNPs, the antibacterial effect of the laser AgNPs lasted over 100 days longer when tested in the 45-day interval, but was susceptible to oxidation when frequently exposed to the air. The laser generated AgNPs had lower antibacterial activity when stored in cold compared to that stored at room temperature. This study demonstrated the long lasting antibacterial durability of the laser generated AgNPs. Such information could help design future medical applications for the AgNPs.

“…And the scissoring and rocking modes of the methylene group were observed at 1462 and 716 cm −1 , respectively, which indicated that AgSt was composed of a triaxial system with two chains per unit cell 43 . It was revealed that it was mainly composed of trace silver and silver stearate 44–45 . This was because of the chemical reaction between stearic acid and WUV@Ag 2 O and the chemical Equations () and () of the reaction were as follows.

2 normalN italicaOH + 2 {AgNO}_{3} = 2 {NaNO}_{3} + H_{2} O + {Ag}_{2} O ↓,

2 C_{17} H_{35} italicCOOH + {Ag}_{2} O = 2 C_{17} H_{35} italicCOOAg + H_{2} O .

In this article, the superhydrophobic and antibacterial surface on the cotton fabric were fabricated with the UV curable waterborne coatings, the silver nanoparticles, and the stearic acid. The cotton fabric coated with silver stearate was obtained by immersing in a mixture of sodium hydroxide and then modified by stearic acid. Results showed that the water contact angle on the surface of the fabric was 157.6°. The micromorphology and chemical ingredients of the surface of the coating were studied by scanning electron microscope, Fourier transforms infrared spectroscopy, and X photoelectric spectrometer. Results showed that the immersion resulted in a double decomposition reaction and with the modification of the stearic acid, the silver stearate was formed on the surface, which provided a rough surface required for super‐hydrophobicity. And the acid and alkali resistance test, water‐resistance test, and antibacterial activity test indicated that the coating had good acid and alkaline resistance, water‐resistance, and antibacterial properties.
