Abstract
The influence of compositions based on 1H,1H,9H-trihydroperfluorononan-1-ol, montmorillonite, and polytetrafluoroethylene Fluralite on the structure and wear resistance of the polyurethane elastomer modified by them is considered. The introduction of polyelement modifiers leads to the reorganization of the amorphous structure of the polymer matrix and changes in the properties of the surface. There is an increase in the intensity of the amorphous halo and a decrease in its radial half-width. According to the methods of X-ray photoelectron spectroscopy and X-ray microanalysis, the surface (up to 3 nm) and deep layers (up to 5 μm) of the modified polyurethane elastomer are enriched with fluorine, which together leads to the formation of a hydrophobic boundary lubricant layer and provides increased wear resistance. The developed polyurethane composites may be of interest as monolithic sports, roofing, and waterproofing coatings.
