The aim of the current work is to modify the surface of the Kevlar fabrics (as membrane support) using three types of nanostructures(as coating layers), PAB-A, boehmite-epoxide, and PC-A, in order to fabricate a nanocomposite membrane with hydrophilic surface and potential to separate oil from oily water emulsions. Beside improved separation performance (water flux and oil rejection)compared to similar works, favorable reusability of the synthesized membranes is expected. SEM, TEM, FTIR, UV/vis spectrophotometer, and water uptake analyses were performed to characterize the membranes. A (gravity-driven) dead-end filtration setup was applied to test the membranes dynamic performances (flux and rejection versus time). Effect of pH as the most important parameteraffecting oil separation using membranes was also studied.
