Therefore, the well known concepts and principles of this science have been applied to a lower scale (Pitteri M, Zanzotto G (2002) Continuum models for phase transitions and twinning in crystals, CRC Press, London) to explain the origin of lamellar twisting during the growth of optically banded spherulites in polymer samples squashed between glass surfaces. The developed model considers that the torsional motion of the lamellae is caused by the presence of thermal gradients across the thickness of the samples and accounts for both morphological and optical characteristics of polymer spherulites.
