Abstract: The potential for creating anti-infective impregnation based on aminopolysaccharide and silver ions is shown. Thanks to a unique water-insoluble complex of silver clusters (Ag 0.034 mg/cm2 of mask material) in natural aminopolysaccharide, the impregnated material exhibits significant antibacterial properties. It has been shown that impregnation does not interfere with the effective removal of carbon dioxide, which can accumulate on the inside of the mask during breathing. It is noted that the use of a new nature-like anti-infective impregnation opens up the possibility of increasing the wear resistance of the impregnated material, while the impregnation is not removed from the surface of the mask material during intensive use of the mask.
Keywords: medical masks, impregnation, aminopolysaccharides, silver, antibacterial effect
