Superabsorbent hydrogels are loosely crosslinked water-soluble polymers, which can
absorb large amount of water, saline solution, or physiological fluids [1,2]. Most of
commercially available superabsorbent hydrogels are crosslinked sodium
polyacrylates, and they have no biodegradability. Since the major applications of
superabsorbent hydrogels are in disposable goods, their use may result in
environmental pollution.
