摘要： An organic/inorganic composite hydrogel can be prepared only through mixing at a room temperature and that has high modulus of elasticity and a self-supporting property that allows a shape to be maintained in water, and a method produces the hydrogel. A hydrogel forming composition that is capable of forming a hydrogel having a self-supporting property, includes: a water-soluble organic polymer having an organic acid structure, an organic acid salt structure, or an organic acid anion structure; a silicate salt; a dispersant for the silicate salt; and a compound having or generating divalent or higher valent positive charge; a hydrogel formed of the composition, and a method for producing the hydrogel.
