I am interested in the chemical aspect of the hydrogel being used so asked the above mentioned question
Dear Sir. Concerning your issue about the chemical components of the hydrogel. Hydrogel products constitute a group of polymeric materials, the hydrophilic structure of which renders them capable of holding large amounts of water in their three-dimensional networks. Extensive employment of these products in a number of industrial and environmental areas of application is considered to be of prime importance. As expected, natural hydrogels were gradually replaced by synthetic types due to their higher water absorption capacity, long service life, and wide varieties of raw chemical resources. Literature on this subject was found to be expanding, especially in the scientific areas of research. However, a number of publications and technical reports dealing with hydrogel products from the engineering points of view were examined to overview technological aspects covering this growing multidisciplinary field of research. I think the following below links may help you in your analysis:

Hello. Several commercial hydrogels are constituted by polyacrylamide or sodium polyacrylate, which are mixed with other monomers to change their properties.
