| Abstract: | The solvability of NMP, DMF for PSF, SPSF was investigated by the viscidity of solutions. The compatibility of PSF/SPSF was characterized by the phase contrast microscope in different NMP/DMF composites. It indicates that the composite and the character of solvents affect the compatibility, and performance of PSF/SPSF alloy membranes. With the DMF increasing, the alloy membrane's flux increases and the retention declines. It is an effective method to adjust and improve the performance of the alloy membrane by changing the composite of NMP/DMF. |
