An overview was given on polymer gel with respect to its structure, gelation process, properties, and applications. In a structural analysis it is necessary to have a different scale depending on the gel structure observed. Properties and responses of polymer gels were widely described with the explanation for solvent properties and phase transition, thermoresponse, chemical response, and electric properties. The potential application of gels has also been shown concerning biomedical use, drug delivery system, and selective separation.
