The Materials in Interactions (MINT) department is dedicated to understanding the mechanisms governing the behavior of materials within complex ecosystems. Given the diversity of ecosystems, ranging from industrial to societal environments, the MINT department prioritizes multidisciplinary approaches.

Research Areas
Material behavior in harsh environments
To extend the service life of materials, the physicochemical aspects of the interaction between materials and the surrounding ecosystem are studied in order to act on degradation mechanisms, using a predictive, preventive, or corrective approach.
The influence of materials in sustainable design
Within a circular economy approach, to promote sustainable product design, perceptions of materials are studied using qualitative and quantitative methods in order to act on the mechanisms of desirability and acceptability of eco-designed and second-life materials.
Physicochemical behavior of surfaces and interfaces
To improve material properties, surface behavior is studied using multi-scale approaches in order to establish relationships between formulations and overall effects. Specific experimental methods are developed for the chemical and micromechanical characterization of surfaces and interfaces, enabling modeling of their role in material processing methods.
Research unit
Through its affiliation with the Georges Friedel Laboratory (LGF), a joint research unit of Mines Saint-Étienne and CNRS, the MINT department promotes multidisciplinary approaches, thereby strengthening the impact and relevance of its work in addressing energy transition and sustainable innovation challenges. This collaborative framework creates a strong synergy between research and application, positioning it as a key player in industrial innovation, particularly in the energy, mobility, and environmental sectors.
