    摘要: The present disclosure provides a method for manufacturing an aerogel blanket, wherein a surface modification process is performed under acid conditions while using a non-toxic catalyst. Under such a process, a solvent substitution process or a washing process may be omitted to simplify the manufacturing process. Further, collapse of a gel structure due to shrinkage is prevented and the efficiency of surface modification is high even when atmospheric pressure drying is performed, so that an aerogel having excellent thermal conductivity and degree of hydrophobicity may be manufactured. Also provided is an aerogel blanket manufactured by the method, thereby having low thermal conductivity and a low moisture impregnation rate since a hydrophobic group is uniformly formed inside a substrate.
