Synthesis of superhydrophobic crack‐free monolithic silica aerogels via a vacuum freeze‐drying process

Journal of the American Ceramic Society, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 12, 2025

Abstract Freeze‐drying is a promising method for drying gels, but it considered incapable of preparing bulk inorganic oxide aerogels. Herein, using tert‐butanol/water co‐solvent as the freeze‐drying solvent, large‐size crack‐free monolithic silica aerogels with different absolute ethyl alcohol to tetraethylorthosilicate molar ratios were successfully synthesized via vacuum process. Superhydrophobicity was then obtained through an efficient chemical vapor deposition hydrophobic modification As ratio increased from 8 16, density, linear shrinkage, specific surface area (SSA), and mechanical properties decreased, while thermal conductivity decreased first increased. The freeze‐dried show lowest density 0.078 g/cm 3 , shrinkage 4.6%, highest SSA 962 m 2 /g, Young's modulus 904.3 kPa, 0.026 W/(m·K). Despite formed fine ice crystals compressing gel skeleton some extent in process, developed mesoporous structure basically preserved, which ensures excellent insulation performance. This study demonstrates that high‐quality can be effectively prepared by method, provides them another independent supercritical fluid ambient pressure methods.
