The antimicrobial activity of polyurethane based nanosilver coating<br /> composit with 5ppm concentration is good. The antimicrobial activity of modified<br /> polymethylmetacrylat based nanosilver coating composit with 7ppm concentration is very<br /> high. The selection of carring material for nanosiluer coat and its coating technology using<br /> biochemical nanosilver colloid, providing not only the stability of coating material but the<br /> disinfection possibility, plays very important role.<br /> 1.
