Abstract
In the present study, the activated carbon composites containing silver (Ag) nanoparticles (Acc-Ag composites) for the production of highly functional wound-dressing additives were fabricated using a thermal treatment under an inert argon (Ar) atmosphere. During the thermal treatment, Ag+ was successfully changed to metallic Ag nanoparticles, and NO3− with a potential cytotoxicity was simultaneously eliminated. The reduction of the Ag+ was confirmed using the XRD and XPS analyses. The optimal manufacturing condition of the Acc-Ag composites was examined with various Acc/Ag ratios, and the Acc-Ag composites still maintained superior pore properties. The deodorizing activity of the Acc-Ag composites was evaluated with the use of the NH3 gas as the deodorization test gas; compared with the pure Acc, the Acc-Ag composites showed an excellent deodorant effect. Furthermore, the antibacterial activity of the Acc-Ag composites was tested against three types of bacterial strain, and the results indicated that the Acc-Ag composites showed an enhanced antibacterial activity. Therefore, the Acc-Ag composites with excellent antimicrobial and deodorant properties have great potential for the functional wound dressings.
