A superabsorbent polymer is such a polymer that is special in how it reacts to water. It has the peculiar trait of having two very different states or shapes:
  • when the surrounding environment is wet, the superabsorbent polymer will attract water molecules and wrap them around itself. It swells depending on how much water it can absorb.
  • when it gets dry, the polymer will release the water and slowly bunch up. It returns to its original, dry, smaller, harder form.
These superabsorbent polymers, or hydrogels, are specifically designed to retain and release water in the hope of helping plants cope with irregular rain or irrigation.
