摘要：
Polyethersulfone (PES)/poly (ether ether ketone) (SPEEK) blends nanofiltration membrane at different SPEEK contents were prepared using a simple dry-jet wet spinning technique. The SPEEK polymer with fixed sulfonation degree was used for membrane preparation and characterized using FTIR and nuclear magnetic resonance (NMR) spectrometer. The morphological and electrical properties of the blends membrane were deduced based on the combination of irreversible thermodynamic model, steric-hindrance pore model (SHP) and Teorell-Meyer-Sievers model (TMS). The modeling results have been analyzed and discussed. The effect of SPEEK content on the blend properties was further Studied in detail by FTIR, DSC and TGA and the results were discussed.
