| Abstract | In this work, tensile dynamic mechanical analysis (DMA) was used to characterise the solid-state rheological properties of a commercial -polyvinylidene fluoride (PVDF) film in the two main directions (longitudinal and transversal to the stretch direction). The -relaxation, assigned to the segmental motions within the amorphous phase, is observed at ∼−25◦C. The c-relaxation is observed above room temperature. This relaxation is the main responsible for the anelastic properties of the material and to the short-term creep behaviour. Longer-term creep tests along the longitudinal direction were also performed and the Eyring model was applied, in order to characterize the flow-process within the polymeric structure. The results suggest that long-term creep is mostly controlled by the deformation of amorphous tie-chains that connect adjacent crystalline lamellae. © 2003 Published by Elsevier B.V. |
