PREPARATION OF TITANIA SOL-GEL COATINGS CONTAINING SILVER

Popis výsledku v původním jazyce

The work describes titania coatings containing various forms of silver applied on a titanium substrate by a dip-coating sol-gel technique. Silver was added into the basic titania sol in form of colloid particles of Ag, crystals of AgNO3, particles of AgI, particles of Ag3PO4 and Ag3PO4 developed in situ (in the sol) by reaction of AgNO3 with added calcium phosphate (brushite or monetite). Mechanically and chemically treated titanium substrates were dipped at a constant rate into individual types of sols. Subsequently, they were slowly fired. The fired coatings contained microcracks. All over the surface there were evenly distributed spherical nanoparticles of silver (Ag, AgNO3) or microcrystals of AgI and Ag3PO4. The prepared coatings were tested understatic conditions for their bactericidal effects against gram-negative bacteria Escherichia coli (E. coli). The coated substrates were immersed into a suspension of E. coli in physiological solution for 24 and 4 hours. The basic titania
