Matériaux/Minéraux lamellaires fonctionalisés et bio-interfaces

 In order to meet environmental and societal challenges, the use of abundant and inexpensive natural or synthetic minerals and materials is particularly important. The modification/functionalization of lamellar materials/minerals and the understanding of the structure-property relations allow to increase their fields of application, which can thus be aimed at catalysis, health, environmental remediation, energy storage or conversion and the development of mineral fillers as polymer additives (nanocomposites). .

The objective of this part is to provide the student with the necessary basis of modified clays, layered double hydroxides and nanocomposites and skills in the synthesis and modification of these materials as well as in characterization (structural/property relationships, advanced characterization methods).
