Influence of the clay content and the polysulfone molar mass on nanocomposite membrane properties

► The wet-phase inversion method is used to prepare PSf nanocomposite membranes. ► SAXRD, TEM, SEM and FTIR techniques are used to characterize PSf nanocomposites. ► A complex intercalated/exfoliated morphology is formed by using low clay contents. ► By increasing clay content and PSf molar mass, mass loss is decreased. ► Mechanical properties are enhanced up to 4.0 mass% MMT addition.
