Abstract

The morphology of PVDF, P( VDF-TrFE) copolymers, and PVDF/P( VDF-TrFE) blend with different compositions were investigated by scanning electrón microscopy (SEM). lt was observed in the lamellar bundle arrangements which form the two different types of spherulites present in PVDF crystallized at 160 °C. The effect of the crystallization temperature on the morphology of the copolymer with 72 mol% of VDF was also investigated. lt was observed for lite PVDF/P( VDF-TrFE) blends a strong influence of the copolymer on the lamellar structures which form the two different types of PVDF spherulites, suggesting the presence of the copolymer molecules in the interlamellar regions of these structures.
