(a) Temperature scan of WAXS profiles recorded during the melting process (3 K min−1) of PTN crystallized at Tc = 423 K. (b) Thermal evolution of structural characterization during the melting process of the PTN coexistent form of α- and β- crystals: DSC thermogram (top), normalized crystallinity (middle) and intensity of Bragg diffraction peaks (bottom). The solid circle and triangle are Bragg peaks of the β-crystal and the open circle and triangle are Bragg peaks of the α-crystal. Those emblematic peaks are marked by (a). |
