Abstract
Provided is a hydrophobic silica aerogel precursor, and a hydrophobic silica aerogel produced using the same. In the methods, a linear silane crosslinking agent containing a PEG-derived unit is introduced when preparing a hydrophobic aerogel precursor, resulting in the production of a hydrophobic silica aerogel having improved high-temperature thermal stability and improved physical properties.
