Effect of coagulation bath temperature on morphology and performance of PES-Aerosil nanoparticle ultrafiltration membranes

Effect of coagulation bath temperature on morphology and performance of PES/Aerosil membranes was investigated. The membranes were prepared from a PES/Aerosil/DMAC system via phase inversion induced by immersion precipitation in a water coagulation bath. The morphology of prepared membranes was studied by scanning electron microscopy (SEM). Permeation performance of the prepared membranes was studied by separation experiments using pure water and NaCl , NaNO3 , CaCl2 solutions. The results show changes in coagulation bath temperature will be changed morphology structure of membranes and ion rejection performances
