Hydrophobic Silica Aerogels Review of Synthesis, Properties and Applications... 

In this chapter, we present a review of the s) thesis techniques for, properties of and applications of hydrophobic silica aerogels. In the following section, we review the techniques used to make silica aerogels. This is followed by sections devoted to the fabrication of hydrophobic aerogels, techniques for measuring hydrophobicity, a review of the literature on hydrophobic silica aerogels, and a summary of application areas for hydrophobic aerogels.

In this article, preparation, properties and applications ofthe hydrophobic silica aerogel will be described mainly on the basis of our work on the silica aerogels. 

In this article, production, properties and applications of hydrophobic silica aerogels have been described. The hydrophobic silica aerogels are at present especially important in the optical application, because they show highly valuable properties which cannot be attained optically by other available materials. So far, silica aerogel incurs high preparation costs due to the specialized process of supercritical drying, and the present consensus is that... 

Although many different varieties of aerogels can be made, the most common is silica aerogel. Without additional modification, silica aerogel is prone to the adsorption of water, which causes collapse of the structure. However, modification of the gel prior to the supercritical drying process with trimethylsilyl results in a hydrophobic silica aerogel [110]. This practice is very common in siUca aerogel production, especially in application as thermal insulation.
