Innovative Materials by MUlti-Nanolayer Extrusion – IMMUNE

The objective of the project proposal “IMMUNE” is to develop new multifunctional materials with highly improved barrier properties compared with conventional materials by using an innovative co-extrusion process giving access to multinanolayered structures. Transport properties of films with controlled architecture (at multi-scales from macro down to nanoscale) based on polyethylene and polyamide matrices containing dispersed graphene and / or montmorillonite nanofillers will be investigated. This process is thought to promote the dispersion and/or the orientation of the nanofiller aggregates by conjugating flow and confinement effect, which should contribute to significant improvements in thermo-mechanical and barrier performances. The properties will be optimized with the number of nanolayers within matrix and the mass fraction of nanofillers and by analyzing the relationship between structural properties and transport properties of the elaborated nanocomposites films with filled stacked nanolayers.
