Antimicrobial effect of hygienic coatings based on photocatalytic additives
Original language description
Antimicrobial paints were based on the aqueous acrylic dispersion and various amounts of nano particles of zinc oxide and titanium dioxide. Antimicrobial ability and photoactivity were assumed in these paints. It was possible to observe the photoactivitythanks to change of organic dyes due to oxidative-reductive reaction. The best photocatalytic effect showed the coating containing 7 vol. % of nano ZnO. This sample showed also the best result in the photocatalytic test, which was better than the resultfor sample containing nano TiO2. The agar dilution method was used to test antimicrobial ability. The Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus were chosen as test bacteria and Penicillium chrysogenum and Aspergillus niger as test mold. The antimicrobial effect of coatings containing 7 vol. % of nano ZnO was the best of all tested samples.
