Hydrophobic Sand on the Basis of Superhydrophobic Soot Synthesized in the Flame

The paper presents the results of studies on the synthesis of superhydrophobic soot, and on the development of its technology-based production of bulk material (sand), which has hydrophobic properties. The hydrophobic properties of sand had attached by fixing soot having superhydrophobic properties of nanoscale layer on the surface of the grains of sand. The resulting sand was examined by scanning electron microscopy to determine the structural and morphological parameters. The resulting composite material is characterized by good water repellent and resistant to external corrosive environments, which allows it to be used in civil and road construction, water-resistant layer for reclamation in hot and arid regions, and in areas where there is a need for bulk materials with hydrophobic properties.
