A hydrogel is an example of a smart material. It can change its
structure in response to saltconcentration, pH and temperature.
What is the Structure of a Hydrogel?
Hydrogels are cross linkedpolymers that have hydrophillic groups.
They are often polymers containing carboxylic acid groups. One
common polymer used to make hydrogels is sodium polyacrylate.
The chemical name for this polymer is poly(sodium propenoate).
The polymer chains usually exist in the shape of randomly coiled molecules. In the absence of Na+ions (if you remove all the the salt) the negative charges on the oxide ions along the polymer chain all repel each other and the chains tend to uncoil
