polymer single crystal

https://doi.org/10.1351/goldbook.14255
Individually distinct polymer crystal whose lattice, at crystallization, is characterized by a single orientation.
Notes:
  1. Polymer single crystals obtained from dilute solutions are comparatively large, i.e, they have lateral dimensions typically of a few micrometers, which can reach tens of micrometers in some instances. They are normally delimited by well-defined boundary surfaces and may, in rare instances, be manipulated individually.
  2. The thickness of individual polymer single crystals (inclusive of the fold surfaces thickness) is now measured by AFM (atomic force microscopy) along with transmission electron microscopy, while average values are derived using SAXS (small-angle X-ray scattering) and SANS (small-angle neutron scattering).
