Results from DSC, SAXS and WAXD show some new insights into the evolution of structural variables during Curie transition in PVDF/TrFE copolymer. The differences of long period evolution between the melt-crystallized samples in the paraelectric phase (> 80 degrees C) and in the ferroelectric phase (74 degrees C) are observed in the Curie transition region for this copolymer, for the first time according to our knowledge. The decrease in the SAXS intensity indicates the electron density in paraelectric phase is less than that in ferroelectric phase. All our data indicate that the Curie transition is a gradual process.
