THIN FILM COMPOSITE MEMBRANES WITH FUNCTIONALIZED STAR POLYMERS

摘要

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.
