Abstract
Provided is a method for preparing a hydrophobic silica aerogel by using a Soxhlet extraction, and a hydrophobic silica aerogel prepared by using the method. Since the preparation method according to the present invention may simultaneously perform washing and drying of a hydrophobic silica wet gel as well as solvent substitution and may remove an extraction solvent without an additional separation process, a hydrophobic silica aerogel having low tap density and high specific surface area may be easily prepared.
