Post-doc position Celluwiz project

• Location

The postdoc will be located at 3SR Lab, a Solids Mechanics research lab of the CNRS and the Univ. Grenoble Alpes, with strong interactions with the projects partners, in particular with CTP. Some of of the experiments will be carried out at ESRF (3D in situ imaging at ID19 beamline)

• Mission

The objective of Celluwiz is to produce multilayered bio-based structures made of paper boards onto which celllulose nanofibrils (CNF) films are deposited via the wet lamination process. These new bio-based fibrous materials exhibit valuable specific mechanical properties and excellent permeability to gases and even to water (if CNF films are properly treated). However, during the wet lamination, many complex mechanisms occur such as the high anisotropic shrinkage of the CNF hydrgogels during their drying, as well as their adhesion to the paper board substrates. These mechanisms are not well understdood and induce important defects on the produced materials : internal stress developpement, high residual strains leading to undesirable curling, clocking and delamination phenomena. The main objective to the postdoc is to characterize these defects, by investigating the hygro-mechanical behaviours of (i) the CNF hydrogels during their drying, (ii) the paper boards, (iii) the multilayered systems.
