Membrane material design

Membrane materials are usually divided into two families: polymeric membranes and inorganic (or ceramic) membranes. Each of these families will make up a part of this course. The first part will be devoted to the design of polymer membranes. In this section, we will focus mainly on phase inversion preparation techniques (NIPS, VIPS, TIPS), with a focus on research and innovation (SNIPS, aquaporin, etc.). Additives (especially pore-forming and hydrophilizing agents), which play an important role in phase inversion approaches, will also be described, as well as the various routes for chemical modification of post-synthesis membranes. The second part will focus on the design of inorganic membranes. In this part, we will present both wet processes, i.e. the main methods of liquid film deposition (dip-coating, spin-coating, sputtering, tape-casting, silk-screen printing) and deposition from solutions (electrolytic or chemical processes) or suspensions (electrophoresis, Langmuir-Blodgett), and dry processes (PVD techniques (evap. and spray), CVD techniques (thermal, PECVD and ALD), MBE, surface treatment). Finally, as an illustration of the two membrane families, we will discuss case studies of membrane applications, notably in the packaging field.

The aim of this course is to apply students' knowledge of polymeric and inorganic materials to the preparation of membranes with their own specific functionalities (thin-film geometry, chemistry/texture compromise for optimum management of the permeability/selectivity functional duality). On completion of this course, students should be able to choose a preparation process adapted to a target membrane function, and master the parameters of this process.
