Airgel on its solid surface can adsorb molecules in the form of gas and liquid. Their adsorption depends on the specific surface area of the porous body. Hydrogel is an aqueous solution of a polymer and can solubilize other molecules in greater quantities than are soluble in water.
Adsorption Capacity: Hydrogels primarily adsorb water and other polar molecules. They have a high water retention capacity due to their ability to absorb and retain large amounts of water, typically many times their dry weight.
Adsorption Capacity: Aerogels can have high adsorption capacities for a wide range of substances, including gases and liquids, due to their large surface area and interconnected nanoporous structure. They are particularly effective at adsorbing low-density gases.
