  "id": "MLC-T-CHM-009134",
  "term": "Polyelectrolyte gel",
  "field": "Chemistry",
  "definition": "A crosslinked polymer network composed of polyelectrolyte chains that swell significantly in a solvent due to the osmotic pressure of counter-ions. The swelling behavior is highly sensitive to changes in pH, ionic strength, and temperature. These gels are often used in superabsorbent materials, sensors, and controlled release systems.",
