  "term": "Spherulite",
  "field": "Chemistry",
  "definition": "A spherical, semicrystalline microstructure that forms in many polymers upon cooling from the melt or during crystallization from solution. It consists of numerous lamellar crystals radiating outwards from a central nucleus, often separated by amorphous regions. Spherulite size and morphology significantly influence the mechanical and optical properties of the polymer material.",
