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.
Claims5
A surface hydrophobically modified hydrophobic silica aerogel blanket, comprising two or more holes having an average diameter of 0.01 mm to 3.20 mm on a surface,
- wherein a gap between the holes is 1.5 mm to 50.0 mm, and
- an aspect ratio of the cross-section of the holes is 1.50 to 5.00.
