Description and schematic (not true to scale) presentation of the four different approaches to combine PEG and PEO (ellipsoids) and PIM-1 (rectangles), physically mixed or chemically bound. Anthracene based copolymer (Section 3.4, Path 4) is depicted as triangle to distinguish from PIM-1.

Path 1 (Section 3.1)	Path 2 (Section 3.2)	Path 3 (Section 3.3)	Path 4 (Section 3.4)
Blend membranes from PIM-1 and different low molecular PEGs	Quenching to form PEO end groups of PIM-1 chains	PIM1(X)-b-PEO(Y)—multiblock copolymers	PEO/PPO in side chain of PIM1 copolymer
