Design of membrane materials

Membrane materials are usually divided into two families: polymeric membranes and inorganic (or ceramic) membranes. Each of these families will constitute a part of this course. The first part will be devoted to the design of polymeric membranes. In this part, we will mainly deal with the techniques of preparation by phase inversion (NIPS, VIPS, TIPS) with an opening on research and innovation (SNIPS, aquaporin...). In addition, the additives (especially pore-forming and hydrophilizing agents), which play an important role in the phase inversion approaches, will be described and the different chemical modification routes of the post-synthesis membranes will be presented. The second part will be devoted to the design of inorganic membranes. In this part, we will present on the one hand the wet processes, i.e. the main methods of deposition of liquid films (dip-coating, spin-coating, sputtering, tape-casting, silk-screening) and of deposition from solutions (electrolytic or chemical processes) or suspensions (electrophoresis, Langmuir-Blodgett), and on the other hand the dry processes (PVD techniques (evap. and spray), CVD techniques (thermal, PECVD and ALD), MBE, surface treatment). Finally, as an illustration of the two families of membranes, we will deal with case studies on membrane applications, in particular in the field of packaging.

The objective of this course is to take advantage of the students' knowledge of polymeric and inorganic materials in order to prepare membranes with their own functionalities (thin film geometry, chemistry/texture compromise for an optimal management of the functional duality permeability/selectivity). At the end of this course, students will be able to choose a preparation process adapted to a target membrane function, and to master the parameters of this process.
