Electron microscopy of banded structures in oriented thermotropic polymers

  • A. M. Donald
  • A. H. Windle


Banded microstructures in thermotropic polymers are analysed by transmission electron microscopy. The banded structures are only apparent in dark field and lie normal to the direction of the shear imposed on the sample when above its softening temperature. Dark field micrographs prepared from different regions of the diffraction pattern demonstrate that the structures are associated with the serpentine path of the polymer molecules about the shear direction.
