Abstract
Methods for producing silver-bonded antimicrobial moist wound dressings include adding a silver-containing compound to a 0.1-30% aqueous solution of an alkaline solvent to dissociate silver ions from the silver-containing compound; dissolving CMC in water or an organic solvent to obtain a CMC solution; mixing the silver ion-containing solution with the CMC solution so that the hydrogen ions (H) of the hydroxyl groups of the CMC are replaced by the silver ions to prepare a silver-CMC compound; dispersing and absorbing the silver-CMC compound in a medium; and drying the medium.
