Abstract
The present invention relates to a method for producing an aerogel blanket exhibiting excellent hydrophobicity at high temperatures and an aerogel blanket produced thereby. The present invention uses a mixture of silica sol and a hydrophobic aerogel powder as an aerogel precursor and thus can achieve hydrophobicity in the internal structure as well as on the surface of the aerogel included in the aerogel blanket. Accordingly, the aerogel blanket can attain high hydrophobicity and thus can exhibit excellent hydrophobicity retention ability even in high-temperature applications.
