چکیده
|
Polyethersulfone microfiltration (mf) membranes can be fabricated by the vapor induced phase separation (vips) process# in this work, the effect of different exposure times of non-solvent vapors and the temperature of the coagulation bath was investigated on the membrane morphology and performance# for this purpose, five membranes have been prepared and comparative analysis was conducted# scanning electron microscopy images showed that the morphology of the membranes was changed depending on the exposure time and the unique morphologies, including an hour-glass structure, can be obtained# also, the comparison between the average pore size and porosity samples revealed that the exposure time is more effective than the temperature#
