These are also called as aqua gels. These are the network of polymer chains that are water insoluble. In this water is dispersion medium. These are very flexible and similar to natural tissue. The polymer chains of hydrogels are cross linked. The nature of connections are different for physical and chemical hydrogels. For physical hydrogels they are held by either electrostatic forces/ hydrogen bonds/ interactions where as for chemical hydrogels they are held by permanent covalent bonds.
