Nanocomposites based on bio-based Poly(ethylene 2,5-furandicarboxylate), PEF, and different nanoclays (either sepiolite or montmorillonite, both organically modified) were prepared by melt extrusion and compression molding. Firstly, the impact of processing at high temperatures on PEF molecular weight is evaluated and correlated to the presence...

Several equations have been compared for the modelling of semi-cristalline polymer crystallization on cooling from the melt and on heating from the glass. The temperature dependence was described with the Hoffman–Lauritzen (HL) equation, where U* and Kg were first determined by fitting the activation energy (Eα) dependency with temperature...

Poly(ethylene 2,5-furandicarboxylate)(PEF), an emerging biobased polyester, was compounded with cellulose via twin-screw extrusion. Different extrusion parameters such as mixing time, screw speed and temperature were employed. Composite thin films containing 1, 2 and 4% cellulose w/w were prepared and compared with neat PEF films. The...

Novel nanocomposites of bio-based poly(ethylene 2,5-furandicarboxylate) (PEF) and organo-modified montmorillonite (OMMT) clays were prepared. Sample morphology was investigated by means of transmission electron microscopy (TEM) and X-ray diffraction (XRD) that revealed a good dispersion of the clay layers in the PEF matrix. Moreover, the effect...
