A new oil fouling-resistant coating based on polydopamine (PDA) was designed by codeposition on the surface of polyvinylidene fluoride (PVDF) microfiltration membranes. The physicochemical properties of the surface-modified PVDF membranes were investigated by attenuated total reflectance-fourier transform infrared (ATR-FTIR) spectroscopy and atomic force microscopy (AFM). The performance of the modified membranes was evaluated with respect to the water flux and rejection properties. The  PDA-based modified PVDF membranes displayed significant enhancement in separating oil from water in tight emulsions while demonstrating remarkably high resistance to fouling in comparison to the unmodified PVDF membranes. This work offered a promising strategy for enhancing the stability of PDA-based coatings for PVDF membranes. The reported functionalized microfiltration membranes can be recommended for water/oil separations.
