Unusual thickness triggered doubling of the volume of LbL-films composed of rigid and soft components
The remarkable properties of natural composite materials (e.g. plant cell wall, animal exoskeleton) have attracted a wealth of research to understand their structure-property relationships at all length scales and to design novel materials with superior mechanical and optical performance. As such complex bio-inspired materials can presently not be made synthetically with a nanoscale precision, ICS and CERMAV propose to combine layer-by-layer assembly and grazing incidence spraying to design hierarchical helical architectures of nanocelluloses and (bio-)polymers with tunable structural features. Preliminary results indicate that this approach is well adapted for designing complex multilayer films. But during this study, films made of tunicate cellulose nanocrystal and poly(vinyl amine) showed a highly unusual film-growth behavior by dipping and grazing incidence spraying methods that is in strong contrast with the literature. In the proposed experiment, neutron reflectivity will be used to provide quantitative data on the multilayered assemblies' dimensions, composition and geometry that will bring valuable insight into the origin of these intriguing physico-chemical phenomena.
