Silver nanoparticle-loaded activated carbon cloths are prepared using a hydro-gel formula in this study. The final amounts of silver nanoparticle loaded range from 24.3 to 180.3 fJ. g/25 cm for the various formulas that inhibit bacterial growth by dynamic contact. For a static contact with Staphylococcus aureus, a 0.01% glycerin formula shows a good disinfectant effect, killing more than 99% of the bacteria after 24 h of contact. Moreover, after 1 h of water dipping, the formulas maintain their static-contact disinfectant effect. As broad-range disinfectants, the formulas are suitable for such diverse applications as water filters, masks, protective clothes and wound dressing.
