Changes in the crystalline phase structures and molecular mobility of a semi-crystalline P(VDF75/TrFE25) have been analyzed using solid-state 19F MAS and 1H19F CP/MAS NMR spectroscopy. The conformational exchange motion at the head-to-tail linkage has a key role for the ferroelectricparaelectric phase transition. The anomalous decrease in the signal intensity of the amorphous peaks and its T1ρF value similar to the crystalline domain at 122 °C indicate the existence of cooperative motion… CONTINUE READING
