摘要:
Disclosed is a method of manufacturing superhydrophobic silica-based powder, including adding a water glass solution, which is not subjected to ion exchange, serving as a precursor, with an organosilane compound having an alkaline pH and an inorganic acid to thus subject the water glass solution to surface modification and gelation, thereby producing hydrogel, immersing the hydrogel in a nonpolar solvent to thus subject the hydrogel to solvent exchange and Na+ removal, and drying the hydrogel, subjected to solvent exchange, at ambient pressure, thereby manufacturing aerogel powder. This invention is very important from an industrial point of view because it involves a very simple process and realizes economic benefits.
