Ferric ions undergo a gelation reaction with acrylic acid to form a polymeric hydrogel. Several articles stated that iron (III) undergoes either a complexation reaction or an electrostatic reaction. Furthermore, calcium, zinc, and copper can also form hydrogels with polyacrylic acid. In all these cases, scientists reported that metal-containing hydrogel showed self-healing properties. By using electrostatic interaction theory, it is possible to discuss the mechanism of self-healing. But if their complexation is present, what would be the possible mechanism?
