## Abstract **Summary:** Poly(ether imide) (PEI) membranes were modified with a linear lowβmolecular weight (PETIM\_0.6) and a branched highβmolecular weight poly(ethylene imine) (PETIM\_60). The membrane surfaces became more hydrophilic and the zeta potentials were shifted from negative to positiv
