METHOD OF PREPARING FOR SILICA AEROGEL AND SILICA AEROGEL PREPARED BY THE SAME

摘要

The present invention relates to a method for manufacturing a silica airgel and a silica airgel prepared thereby, the nucleation step of forming silica colloidal particles using a low concentration of silica precursor and the addition of a relatively high concentration of silica precursor to seed the colloidal particles By using the two-step process of the growth step of forming a silica wet gel with (seed), the mechanical stability is improved, the pore characteristics are improved, and a method for manufacturing a silica airgel that is easy to control physical properties and a silica airgel produced thereby are provided. do.
