Does precipitated silica also have hydrophobicity
Precipitated silica is usually a hydrophilic inorganic material, widely used in various industries due to its excellent dispersibility and thickening properties. In contrast, hydrophobic carbon black is more suitable for certain specific application areas.
However, if the structure or surface treatment of precipitated silica is carried out, it can also be made hydrophobic. For example, by surface modification of precipitated Bailing Hall carbon black, such as silane coupling, hydroxylation, esterification, etc., its surface can become more hydrophobic. This modified precipitated silica has broad application prospects in polymer composites, coatings, inks and other fields.
