Abstract

Composite membranes for nanofiltration were prepared by a polycondensation reaction between trimesoylchloride and different amines inside a dense layer of poly(ethylene oxide-b-amide). Use of amines containing ethylene glycol blocks resulted in membranes with best performance; hydrophilic membranes with a cut-off as low as 600 g mol-1 and a reasonable water permeability, around 3 1 h-1 m-2 bar-1 were produced.
