Abstract

See full text

A hydrogel that exhibits excellent water absorbency even when dried, and has flexibility, shape stability, and shape retention properties, and a method for producing the hydrogel. A hydrogel comprising a water-soluble organic polymer, a silicate, a dispersant for the silicate, and a water-absorbing polymer. A method for producing a hydrogel including a formation step of forming a hydrogel comprising a water-soluble organic polymer, a silicate, a dispersant for the silicate, a water-absorbing polymer, and at least one solvent selected from the group having water and a water-soluble organic solvent, and as an optical step, a solvent removal step of removing a portion of the solvent in the hydrogel.
