5.1 Comparison of Isothermal Melt and Cold Crystallization
Kinetics in 5P-EtFLEt-P5
This study was motivated by previous findings demonstrating differences in the
crystallization kinetics of various polymers characterized by a crystalline state on
cooling and heating. These findings revealed that at identical temperatures, cold
crystallization is generally faster than melt crystallization. Nevertheless, no universal
trend was found for other crystallization parameters, including the crystallization
activation energy and Avrami exponent n A . The 5P-EtFLEt-P5 liquid crystal offers
a rare opportunity to investigate both melt and cold isothermal crystallizations: The
thermal treatment protocols are presented in Fig. 6a, b.
Fig. 6 Schemes presenting thermal treatment applied in order to study isothermal melt (a) and
cold crystallization (b) and dielectric spectra of the real ε (c, d) and imaginary ε (e, f) parts of
the complex dielectric permittivity as a function of frequency measured at 271 K during isothermal
melt and cold crystallization as indicated for 5P-EtFLEt-P5. Adapted with permission from [20].
