SP4: Surface effects & coatings

Structured Project 4: Surface effects & coatings

Coordinated by Céline Léonard (MSME)

Coatings have a privileged place in the idea of materials for sustainable construction as they can strongly
contribute to the extension of their service life or they can also propose new functionalities.

Studies on graphene-based coatings will be extended to more complex materials based on polymers, possibly of bio-based origin.

The questions that will be addressed will relate not only to the functional property of the coating, but also to the procedures for its installation on solid supports (projections, etc.), as well as to its mechanical properties to ensure its durability. Fanny SCHNETZ project.

The project opens up to the study of hybrid thin films between a porous oxide substrate and a polymer structure, which raises different types of questions: experimental, on the feasibility of such structures and their characterization; theoretical, on the growth conditions of porous substrates and on their interaction with organic molecules.



Regarding sensors, the objective is to design the most selective devices at the experimental level with the assistance of modeling for the detection of polluting molecules or nanoparticles. These sensors can therefore be used to characterize the impact of the materials used in construction (concrete, wood, etc.) on the quality of the ambient air. Mbaye DIENG project.

Another project will examine the mechanisms of growth of amorphous oxide films (such as silica, alumina, zirconia,…) produced by physical vapor deposition, with a particular emphasis on identifying the conditions in which these films are porous, and on assessing their possible affinity for small molecules. Nikita SHCHEBLANOV project.

Very different and complementary methodologies, but also multi-scale approaches will be necessary to answer these questions, involving both experimental and numerical studies.
