Hydrogels - Water-Absorbing Polymers
A Catalyst article about hydrogels. Soft contact lenses, disposable nappies, hair gel and plant water crystals all make use of substances called hydrogels. These are polymers which have the unusual property of being able to absorb huge quantities of water. The article looks at the structure of hydrogels and their uses; there are also two experiments that can be carried on domestic products.
