(54) | SELF-CLEANING COMPOSITE MATERIAL, RESPECTIVE METHOD OF OBTENTION AND USES THEREOF |
(57) The present disclosure relates to a self-cleaning composite material capable of removing contaminants, in particular stains or spots, of solid structures after activation. Thus, the present invention describes self-cleaning structures, particularly rigid, flexible or mixed structures, and processes for producing such self-cleaning structures, especially indicated for clothing and textile articles.
The referred self-cleaning composite material, by activation, comprises a substrate, a plurality of nanocomposites; wherein each nanocomposite comprises in its core SiO
2 particles coated with TiO
2 particles, wherein the nanocomposite is covalently linked to the substrate, in particular by the linkage of a silane group to a hydroxyl group.
