Polymer networks

The submersion of a polymer network with a high density of hydrogen bond based cross-links in an aqueous bath results in the formation of a rubber-like hydrogel. The cross-links, which connect chains and maintain the structure of the network, can dissociate as a result of two main factors: (1) the interactions between the hydrogen bonds and the surrounding water molecules and (2) the forces that are exerted on the cross-link from the interconnected chains.
