 Morphology Types

 

  The crystallization of flexible chain polymers can be carried out by supercooling a solution or a melt in which, initially, the chain units are either randomly arranged (isotropic fluid) or partially ordered (liquid crystalline mesophase).

 

1. Faceted single lamellas containing folded or extended chains,

2. Nonfaceted lamellas,

3. Branched (dendritic) structures,

4. Sheaf-like arrays of lamellar ribbons (axialites, hedrites),

5. Spherulitic arrays of lamellar ribbons (spherulites),

6. Fibrous structures,

7. Epitaxial lamellar overgrowths on microfibrils.
