In the membrane separation field, utilizing nanocomposites is an interesting approach to enhance the water permeability and rejection properties of conventional membranes. In the present research, effects of magnetite (Fe3O4) nanoparticles by loading in polymerization precursor solutions, on the surface characteristics of polyamide and polysulfone layers have been investigated. The surface and cross section morphology, contact angle and surface energy, and surface area of polymeric layers has been studied by scanning electron microscopy, contact angle measurements, and BET N2 adsorption/desorption method. Also, X-ray diffraction used for checking dispersion state of particles. The samples were implemented to the different magnetite nanoparticle volume percent caused to the variation of surface and porosity characteristics.
