This study aims to prepare a polymer-coated mesh which could achieve good oil-water separation efficiency with an antibacterial property. These polymers were synthesized by the polymerization process of [3-(methacryloylamino) propyl] trimethylammonium chloride (MAPTAC). The hydrolysis resistance and the swelling ratio of the polymers were also examined in order to choose a suitable oil-water separation material. The prepared meshes showed not only high oil-water separation efficiency (>99%) with high permeate flux (up to 4,308 L h-1 m-2), but also a good antibacterial property. In addition, the oil-water separation efficiencies exceed 99% even under various severe conditions, such as acidic (1 M HCl), alkaline (1 M NaOH), and salty (8 wt.% NaCl) solutions. The excellent durability of the polymer-coated mesh shows the fact that it is a facile and promising filtration mesh for oil-water separation.
