Performance of novel nanocomposite hydrophobic polyethersulfone membranes for desalination by membrane distillation

In the present work, the polyethersulfone (PES) nanocomposite flat sheet membranes for direct contact membrane distillation (DCMD) were prepared through phase inversion process. Also, the surface of Co3O4 nanoparticles were modified by oleic acid (OA). The surface chemistry of the modified Co3O4 nanoparticles was characterized by Fourier transform infrared spectroscopy (FTIR). After modification with OA, a superhydrophobic surface with water contact angle of 88° was obtained. Finally, the amount of flux and rejection for modified membranes were obtained 7.8 kg/m2h and 99.3%, respectively
