FIELD: chemistry.
SUBSTANCE: invention relates to porous anatase titanium dioxide coatings with improved photocatalytic activity used as antibacterial and self-cleaning coatings. A sol-gel composition having at least one agent for forming the sol-gel composition and a porous structure is prepared and deposited on a glass substrate. The coated substrate is heated to remove the agent for forming the sol-gel composition and a porous structure. The agent for forming a porous structure is selected from a high-polymer substance.
EFFECT: porous anatase titanium dioxide coatings have at least one of the following properties improved: antibacterial properties, self-cleaning properties, hydrophilic properties and/or temperature resistance.
