Assembly of nanocomposite PEBAX membranes: A complementary study of affinity and clusterization phenomena

► Pebax and KET used as nanocomposite membranes. ► The reciprocal affinity indicates good miscibility with KET up to 50 wt% and discrepancies at 70 wt%. ► Analysis show segregation phenomena. ► KET migrates toward polar moieties of Pebax. ► Water prefers to interact with KET.
