    Abstract: Provided is a hydrophobic silica aerogel blanket comprising holes, so that the diffusion of a surface modifier is facilitated in a blanket during a surface modification process to improve the efficiency of surface modification. Accordingly, the hydrophobic silica aerogel has not only excellent physical properties such as specific surface area and thermal conductivity, but also a controlled degree of hydrophobicity, and thus, can have high hydrophobicity.

    Abstract: Provided is a method for producing hydrophobic silica aerogel granules and hydrophobic silica aerogel granules produced thereby, the hydrophobic silica aerogel granules having a suppressed level of specific surface area deterioration and scattering properties. In the method for producing the hydrophobic silica aerogel granules, surface modification, gelation, and solvent substitution can be simultaneously performed in one step, thereby decreasing production time and increasing productivity. Also, by adjusting the addition amount of a non-polar organic solvent when proceeding with a reaction, hydrophobic silica aerogel granules with suppressed scattering properties can be produced. In addition, the hydrophobic silica aerogel granules are silica aerogel particles induced to agglomerate with each other through physical bonding, so that there is an advantage in that the granules can be easily changed into a powder form, thereby having excellent industrial applicability.
