Crystallization temperature of zro
WebThe crystallization of ZrO 2 films annealed at different temperatures was measured by XRD, as shown in Fig. 5(b). Except for the ZrO 2 film post-annealed at 400 °C, the ZrO 2 films annealed at the other three temperatures were amorphous, which was consistent with the TG-DSC result. WebFractionated crystallization occurred in these PVDF nanodroplets with the heterogeneously nucleated crystallization in the range of 105–135 °C and the homogeneous nucleation at 55–60 °C. The mechanism of homogeneous nucleation was confirmed by the study of crystallization kinetics using differential scanning calorimetry.
