Nonwoven materials based on polypropylene with up to 2 wt% added sodium nitrate, which allowed the fiber diameter to be reduced by 40%, were studied. The composition and structure of the materials were characterized using IR spectroscopy and x-ray structure analysis. The characteristics of obtained nonwoven materials with low-molecular-mass additives of an ionic liquid and sodium stearate were compared. The surface properties, sorption capacity, and ability for oil recovery were studied to assess the suitability of using the obtained fibrous materials to collect hydrocarbons from water.
