Abstract Polyethersulfone hollow fiber membranes doped with polyaniline were coated by interfacial polymerization (IP) using different monomer pairs. The coated fibers were characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, and atomic force microscopy, water contact angle (CA), porosity, and mechanical properties. Moreover, the performance of coated fibers has been tested at low to medium pressure by measuring pure water flux and magnesium sulfate salt solution. Characteristics and performance have been assessed and compared for all samples. Porosity decreased for all coated samples as compared to the raw sample. Optimum results were obtained using m‐phenylenediamine and trimesoyl chloride depicting the lowest water CA (68°), highest Young's modulus (183 MPa), lowest pure water flux (0.28 LMH/bar), and the highest salt rejection (63% at 9 bar).
