This position is part of the ANR Anisofilm project that brings together 6 academic partners: the LRP, LGP2, CERMAV and DCM laboratories in Grenoble, the Phenix laboratory in Paris and the LPS in Saclay.
The project's main objective is to produce partially biobased hybrid thin films with controlled organization and orientation at different length scales to benefit from physical properties (e.g. mechanical, barrier, electrical) and to target microelectronics and packaging applications or optical coating sector.
The chosen strategy will consist of controlling the organization of suspensions of biosourced nanoparticles (nanocelluloses) associated with inorganic nanoparticles using a tangential ultrafiltration process and then fixing the structures formed by crosslinking under ultraviolet (UV) radiation.


Depending on the properties and applications targeted, the candidate will initially seek to develop stable formulations by associating nanocelluloses (nanocrystals or nanofribrils) with inorganic nanoparticles such as clays or carbon nanotubes. He or she will then focus on the fabrication of hybrid nanocomposite films with controlled organization and orientation by playing on different physico-chemical parameters (e.g. concentration, dimensions and form factor of the nanoparticles present in the initial suspension) and process parameters (shear, pressure, time, etc.). Special attention will be given to detailed structural characterization in situ during the organization process and ex situ after cross-linking. For this purpose, radiation scattering and diffraction techniques (X-rays, light) combined with scanning and transmission electron microscopy will be used. Finally, the developed hybrid thin films' physical properties (e.g. electrical conduction, barrier properties) will be evaluated.


The candidate should have a good knowledge of physical-chemistry of colloids and polymers and a strong interest in experimentation. Knowledge and/or experience in the field of bio-based materials and/or structural characterization and/or membrane separation processes will be an asset. The candidate will have to show enthusiasm, initiative and autonomy to develop this project and will have to appreciate teamwork. Good communication skills and fluency in English are required.

Work Context

The research work will be carried out at the Centre de Recherches sur les Macromolécules Végétales (CERMAV, UPR CNRS 5301) located on the Grenoble University campus. With 140 staff, the CERMAV is structured around 5 research teams whose expertise ranges from carbohydrate chemistry to biomaterials science. The originality and strength of the CERMAV are based on a strategy combining fundamental and applied research. Its multidisciplinary approach combining chemistry, physical chemistry and biology enables it to occupy a leading position in the flagship field of glycosciences, ranging from complex carbohydrates (sugars, oligo- and polysaccharides, glycopolymers and glycomaterials) involved in biological processes and health, to biosourced materials
Specifically, the candidate will be integrated in the Structure Properties of Glycomaterials team, which has international recognition in the field of biobased materials. The work will be part of an ANR project and will be the subject of very close collaboration with the neighboring Rheology and Processes Laboratory.
