Abstract
Antifouling membranes have gained considerable interest in water filtration applications. A dual layer of nonwoven nanofibers membranes was fabricated via the electrospinning method using hydrophilic and hydrophobic polymers. The first (base) layer was hydrophilic polyacrylonitrile (PAN) based electro spun nanofibers. In contrast, the second (top) layer was hydrophobic polymethyl methacrylate (PMMA) based electro spun nanofibers. A series of dual-layer nonwoven nanofiber membranes with various PAN: PMMA amount percentages were fabricated and characterized regarding their morphology and chemical composition using Scanning electron microscopy (SEM) and X-ray diffraction (XRD). The chemical functional groups on the membrane surface were detected using the Fourier transform infrared (FTIR). Also, the roughness and wettability of the membrane surface were measured using the atomic force microscopy (AFM) and the contact angle, respectively. The prepared nanofiber membranes efficiency was examined in emulsified oil/water separation using a crossflow filtration system. The results showed that the fouling resistance and permeate flux were significantly improved by spinning the hydrophobic (PMMA) nanofibers on the surface of the hydrophilic (PAN) nanofibers membrane.
