Shish-kebab structure

{
  "id": "MLC-T-CHM-010824",
  "term": "Shish-kebab structure",
  "field": "Chemistry",
  "definition": "A distinctive morphology observed in semicrystalline polymers, particularly after crystallization under flow or stress. It consists of a central, extended-chain fibrillar core, referred to as the 'shish', from which lamellar crystals, known as 'kebabs', grow epitaxially and periodically along the shish axis. This structure is often found in high-molecular-weight polymers processed by techniques like fiber spinning or injection molding.",
