Abstract: Aerogel is a kind of porous nanostructured material that possesses many advantages including high specific surface area,high porosity,low density,low thermal conductivity and high adsorption properties,etc.Aerogels have been widely used in the fields of thermal insulation,sound insulation,optical devices,supercapacitors and so forth.Proper modification of aerogels can further expand the function of aerogels.Hydrophobic modification,which can make aerogels with specific affinity for different liquids,is a hot research direction of aerogels in recent years.Hydrophobic aerogels are commonly used in adsorbing materials and thermal insulation materials.The main methods reported for hydrophobic modification are in-situ treatment,chemical vapor deposition,surface post-processing and cold plasma technology.The preparation methods and application of hydrophobic aerogels were mainly introduced.
