THIN FILM COMPOSITE MEMBRANES WITH FUNCTIONALIZED STAR POLYMERS

A thin film composite membrane (TFC) includes an active layer (26) on a support (24). The active layer (26) includes at least 8 barrier layers (28) of star-polymers each having at least three linear polymers attached at a central core. Each of the barrier layers (28) has a thickness between 5 and 50...

Zusammenfassung:	A thin film composite membrane (TFC) includes an active layer (26) on a support (24). The active layer (26) includes at least 8 barrier layers (28) of star-polymers each having at least three linear polymers attached at a central core. Each of the barrier layers (28) has a thickness between 5 and 50 nm, and the barrier layers (28) have alternating charge. L'invention concerne une membrane composite à film mince (TFC) comprenant une couche active (26) sur un support (24). La couche active (26) comprend au moins 8 couches barrières (28) de polymères en étoile ayant chacune au moins trois polymères linéaires fixés au niveau d'un noyau central. Chacune des couches barrières (28) présente une épaisseur comprise entre 5 et 0 nm, et les couches barrières (28) présentent une charge alternée.
