Water and aerogel are generally considered hydrophilic, meaning they have a strong affinity for water. Aerogel powder is composed of the same material as conventional aerogel, so it should also be hydrophilic. Coating water and surface with aerogel should result in hydrophilic rather than hydrophobic behavior.

However, there are methods by which aerogel can be made hydrophobic. One such method is to treat the aerogel with a hydrophobic coating such as silica or fluorinated compounds. This can result in hydrophobic behavior of water and surface coated aerogel powder.

Importantly, aerogel has high porosity and surface area, making it an ideal material for use as a carrier for catalysts, adsorbents, and other materials. Treating the aerogel to impart hydrophobic properties can significantly improve its performance in these applications. #chemistry #experiment #pip
