Polymer gels have unusual properties, including the ability to absorb water in volumes hundreds of times greater than their own. For example, some hydrogels are capable of holding up to two kilograms of water per gram of dry gel. By changing the temperature or adding solvents, various desired properties can be achieved. This is why polymer gels are used in industry and biomedicine, including for the targeted delivery of medication, creation of artificial skin, children s toys, etc.
