Abstract
Official abstract text for this publication.
The present invention provides an aerogel and a method for manufacturing the same, in which the size of the particles can be prepared to be very small and uniform because aerogel particles can be formed in the emulsion, and through this, the size of the pores forming the aerogel can also be prepared to be uniform, and furthermore, since an additional post-treatment step is not required, the excellent properties of the aerogel can be sufficiently used without mechanical deformation of the aerogel to enhance the utilization in various industrial fields.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for manufacturing a hydrophobic aerogel, comprising the steps of: (1) preparing a mixed solution of a silicate-based compound, an organosilane-based compound and a surfactant, wherein the weight ratio of the surfactant and the organosilane-based compound is 1:0.1 to 10, and the surfactant is a hydrophobic surfactant having an HLB value of 1 to 8; (2) preparing a hydrogel comprising a plurality of fine aerogel powder particles by adding an acid and a non-polar solvent to the mixed solution and stirring; and (3) drying the hydrogel to manufacture a hydrophobic aerogel. 2 . The method of claim 1 , wherein the method for manufacturing a hydrophobic aerogel does not further comprise a post-treatment step of mechanically micronizing the fine aerogel powder particles. 3 . The method of claim 1 , wherein the organosilane-based compound is any one selected from trimethylchlorosilane (TMCS), hexamethyldisilazane (HMDS), methyltrimethoxysilane, trimethylethoxysilane, ethyltriethoxysilane and phenyltriethoxysilane.
