Membrane material design

Membrane materials are usually divided into two families: polymer membranes and inorganic (or ceramic) membranes. Each of these families will be covered in this course unit. The first part will focus on the design of polymer membranes. In this part, we will mainly discuss phase inversion preparation techniques (NIPS, VIPS, TIPS) with an overview of research and innovation (SNIPS, aquaporin, etc.). In addition, additives (particularly porogens and hydrophilic agents), which play an important role in phase inversion approaches, will be described, and the various methods of chemical modification of 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, wet processes, namely the main methods of liquid film deposition (dip-coating, spin-coating, spraying, tape-casting, screen printing-screen engraving) and deposition from solutions (electrolytic or chemical processes) or suspensions (electrophoresis, Langmuir-Blodgett), and dry processes (PVD techniques (evaporation and spraying), CVD techniques (thermal, PECVD, and ALD), MBE, surface treatment). Finally, to illustrate the two families of membranes, we will discuss case studies on membrane applications, particularly in the field of packaging.

The objective of this course unit is to build on students' knowledge of polymeric and inorganic materials with a view to preparing membranes with specific functionalities (thin-film geometry, chemistry/texture compromise for optimal management of the permeability/selectivity duality). Upon completion of this course unit, students will be able to choose a preparation process suited to a target membrane function and master the parameters of this process.
