“…Both situations lead to similar durability results. The antimicrobial durability is much better than that of coatings with silver ions, whose antibacterial rate was reduced to lower than 99% after 12 washing cycles [13]. The results verify the reservoir function of silver nanoparticles.…”

“…An amount of 2 mmol/L of NaBH 4 solution was slowly added into the suspension under continuous stirring. The obtained nano-silver-containing zeolite or montmorillonite was mixed with the solution of 0.03 mol/L silver, 0.06 mol/L copper and 0.06 mol/L zinc ions, stirring for 5 h, then washed and dried following the procedures described in [13]. The solid product was then added to the hydrophilic polymer solution of PAM (1 wt.%), Na-alginate (3 wt.%) and Na-CMC (7 wt.%).…”

“…Ion-exchanged LTA zeolite and montmorillonite were prepared according to our previous work [13]. A total of 0.5 g ion-exchanged LTA zeolite or montmorillonite was mixed with the nano-silver suspension and the mixture was stirred for 1 h at room temperature.…”

“…Due to the limitation of the interlayer domain, the size of silver nanoparticles generated is smaller, which enhances the antibacterial effect of silver nanoparticles. In addition, the space of interlayer domain becomes larger after the formation of nano-silver, which can be increased from 1.45 nm to 1.54 nm [13,26]. The increased interlayer domain cannot only accommodate a large amount of nano-silver, but also provide more space and sites for subsequent ion exchange.…”

“…As a releasing antibacterial agent, silver ions are released through ion exchange with environmental ions and diffuse and migrate to the coating surface to play the bactericidal role. However, antibacterial agents based on ion exchange characteristics are easy to release silver ions under wet conditions or during coating cleaning, resulting in a rapid loss of silver ions and, thus, the poor durability of the coatings [13]. In recent years, nano-silver particle antibacterial agents are expected to solve the problems of excess release and insufficient storage.…”

Nano-silver is characterized by broad-spectral, strong and stable antibacterial properties, which make it a promising material in coating applications. However, the efficiency of nano-silver is generally low in the coating of films. Here, we developed a series of highly active and durable silver ions–nano-silver antimicrobial agents for powder coatings. To optimize antimicrobial activity and durability, two different nano-silver generation methods, i.e., in situ and ex situ methods combined with different carrier materials, i.e., zeolite with high ion-exchange ability and montmorillonite of layered structure were adopted and investigated. All four antibacterial additives show high activity with a reduction rate of over 99.99% and R value of over 5. The ex situ generated nano-silver antibacterial agents with both carriers exhibit higher activity in the initial antibacterial property and antibacterial durability that the coating films are able to maintain over 99% antimicrobial reduction after 20 cycles (1200 times) of soap solution wiping. They also show a lower yellowish color difference of less than three compared to the films with in situ generation method. The one with montmorillonite as carrier shows the stronger antibacterial property with an R value of 5.88 and slightly better film appearance of lower color difference, smaller reduction in gloss and increase in haze as compared to zeolite carrier due to the layered structure.
