Abstract
Provided are a method for preparing a hydrophobic silica aerogel by the combined use of a first surface modifier and a second surface modifier, and a hydrophobic silica aerogel prepared by using the method. A hydrophobic silica aerogel having excellent physical properties and pore characteristics as well as a high degree of hydrophobicity may be prepared with high efficiency by the preparation method according to the present invention.
