Structure of Hydrogels

The minor objective of this article is to know about Structure of Hydrogels. Hydrogels studied here consist of polymer networks. Polymers are molecules composed of a large number of covalently bound repeating units which can be spatially arranged in different ways. Three dimensional (3D) network structures can be formed starting from linear polymer chains by introduction of intermolecular cross-links. It also gives a measure of polymer molecular weight.
