The aim of this work is to provide a better understanding of the mechanical behaviour as well as of the associated microstructural development of a biobased polymer, named PEF. Indeed, this polymer is more and more evocated to replace one of the polymer used in food packaging, PET. PEF is identified as the biobased counterpart of PET. The...

The biaxial behavior of PEF has been analyzed for equilibrated and simultaneous biaxial stretching. The ability of PEF to develop an organized microstructure through strain induced crystallization (SIC) has been described. Upon biaxial stretching, SIC can be difficult to perform because the stretching is performed in two perpendicular...

Le poly(éthylène 2,5-furandicarboxylate), plus communément appelé « PEF » est un nouveau venu dans le monde des polymères. Il s'agit d'un polymère qui est considéré comme l'analogue entièrement biosourcé du poly(éthylène téréphtalate) ou « PET », issu de la pétrochimie. Bien que ces deux molécules soient très proches (Figures 1 et 2), la...

The emergent biobased polymer poly (ethylene 2,5-furandicarboxylate), PEF, has been studied through an innovative approach based on pole figures and orientation factor calculation. PEF uniaxial stretching was performed with different mechanical conditions (different equivalent strain rates), up to several levels of strain and while considering...

Poly(ethylene 2,5-furandicarboxylate), referred to as PEF, was uni-axially stretched for temperatures above glass transition temperature. This bio-based polymer is considered as a serious competitor for the petroleum analogous poly(ethylene terephthalate), named PET. To replace PET in bottle forming, PEF has to be deformed to large strains...
