  Description du sujet:

This PhD project, recently funded by the Jean-Marie Lehn foundation, aims at developing bio-inspired
multifunctional nanocomposite materials with complex anisotropies (e.g. helical superstructures) combining
steel-like mechanical properties and optical properties of interest (selective optical filtering).

The present PhD work will focus on (i) the fabrication of hierarchical helical architectures made of cellulosic nanofibers and (bio-)polymers with tunable structural features (pitch, handedness) by combining layer-by-layer
assembly and grazing incidence spraying and (ii) their structural and optical characterization using advanced
characterization tools (e.g. SEM, UV-Vis spectroscopy, circular dichroism, Muller matrix polarimetry).

Products that could be developed during this project are damage resistant optical filtering thin films, which
