ABSTRACT:
The present invention provides a novel organic/inorganic hybrid hydrogel which is superior in homogeneity, transparency, mechanical properties, and in swelling and shrinking properties, a manufacturing method therefor, and a dry body of the organic/inorganic hybrid hydrogel which is obtained by removing water from said hydrogel. The organic/inorganic hybrid hydrogel comprises a water soluble polymer (A), a water swelling clay mineral (B) which can be homogeneously dispersed in water, and water (C), and water (C) is included in a three-dimensional network formed by (A) and (B).
