The novelty of this work was to blend different phases of molybdenum disulfide (MoS<sub>2</sub>) in isotropic polyethersulfone (PES). We prepared isotropic PES membranes by optimizing nonsolvent vapour-induced phase separation (VIPS). Membranes were blended with MoS<sub>2</sub> nanosheets of different phases to promote separation performance and antifouling resistance. FE-SEM revealed the flower-like surface morphology of MoS<sub>2</sub> nanosheets. HR-TEM of MoS<sub>2</sub> revealed 2H domains in the monolayer, flakes of a few layers and a <i>d</i>-spacing of 0.22 nm. Raman spectroscopy could be used to distinguish mixed-phase MoS<sub>2</sub> from single-phasRSC advances12058-12070https://www.ebi.ac.uk/biostudies/studies/S-EPMC11019293biostudies-literatureOptimization of isotropic MoS<sub>2</sub>/PES membranes for efficient treatment of industrial oily wastewater.PMC11019293Kayanja OKhalil ASGHassanin AOhashi HHassan MAfalseOptimization of isotropic MoS<sub>2</sub>/PES membranes for efficient treatment of industrial oily wastewater.Elimination of tiny oil droplets nearly miscible with wastewater can be realized using membrane technology through ultrafiltration.
