Abstract
The invention relates to use of masterbatches containing high concentrations of antimicrobial materials such as copper salts, particularly copper iodide. These masterbatch compositions are added to other materials which are used to form various articles of manufacture with antimicrobial properties. The copper salts may be incorporated in the masterbatches as surface functionalized particles or the salts may be incorporated into porous particles prior to the formation of masterbatches.
