Abstract
To prevent materials from mould damage nanostructured metallic coatings were used. Silver, copper and titanium coatings were deposited on different materials. Deposition of metal from plasma flow, generated by vacuum-arc discharge, forms coating with highly dispersed polycrystalline structure. Average size of metal grains in copper or titanium coatings is ~10-15 nm, in silver coatings it reaches ~ 20-25 nm. Both paper and plastic materials with nanostructured metallic coatings showed high fungitoxicity unlike the same metal plates. The reason of that phenomenon may be that during oxygen chemisorption oxides of metals occur. Metals and their oxides formed coating with a highly polycrystalline structure and their fungi toxicity can vary.
