Structure, properties, and phase transitions of melt-spun poly(vinylidene fluoride) fibers
(21–35)Journal of Applied Polymer  Science 120 #1 (2011)
Abstract
Steinmann et al observed an oriented mesophase and deformed crystal structures in all fibers and assigned to the mechanical stress occurring in the processes.  Furthermore, several phase transitions during melting and two mechanical relaxation processes could be detected.  The detailed information about phase transitions and the related temperatures are used to produce fibers with an extended amount of β-phase crystallites, which are responsible for piezoelectric properties of the material.  (RDC 1/10/2011)
