摘要： The present invention relates to a method of preparing an ultra-light metal oxide-silica composite aerogel having high specific surface area and high pore volume and a metal oxide-silica composite aerogel prepared thereby. The preparation method according to the present invention may not only have good economic efficiency because production costs are relatively reduced in comparison to the related art, but may also effectively prevent the collapse of a pore structure by suppressing a shrinkage phenomenon during drying, and thus, a metal oxide-silica composite aerogel having ultra-light properties as well as high porosity characteristics, such as high specific surface area and high pore volume, may be prepared.

摘要： Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol is sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

摘要： The present invention relates to a method of preparing a hydrophobic metal oxide-silica composite aerogel, in which a degree of hydrophobicity may be controlled while having a high specific surface area and a low tap density, and a hydrophobic metal oxide-silica composite aerogel prepared thereby. The preparation method according to the present invention may not only have excellent productivity and economic efficiency due to a relatively simpler preparation process and shorter preparation time than the related art, but may also perform an effective surface modification reaction by using a small amount of a surface modifier. Thus, since the surface modification reaction may be easily performed by using only a very small amount of the surface modifier, a hydrophobic metal oxide-silica composite aerogel containing about 1 wt % to 2 wt % of carbon may be prepared.
