Abstract
Provided is a method for manufacturing an aerogel blanket having improved processability by reducing manufacturing time and cost, the method including the steps of mixing a precursor material, an acid catalyst and a hydrous alcohol to prepare a sol, depositing a substrate in the sol, and reacting with a gaseous silazane-based compound to form a gel and to perform aging and surface modification reaction simultaneously to form a wet gel blanket, and drying the wet gel blanket to manufacture an aerogel blanket.
