  "term": "Folded-chain crystal",
  "field": "Chemistry",
  "definition": "A type of polymer crystal in which individual polymer chains repeatedly fold back upon themselves to form lamellar structures. These crystals are characterized by a regular arrangement of chain segments within the lamella, with the folds occurring at the lamellar surfaces. This morphology is common in semicrystalline polymers and contributes to their mechanical properties.",
