- Abstract
- To address the poor oil-water separation efficiency and bactericidal properties of existing oil-water separation membranes for the treatment of industrial oily wastewater discharge, this study designed an in-and-out coating material for modifying the inner site and outer surface of porous activated carbon fabric (ACF) using urethane reactions. To this end, fluorinated polyurethane (F-PU) coating materials were synthesized using perfluoroalkyl alcohol, ethylene glycol (EG), and isophorone diisocyanate (IPDI). Subsequently, the inner and outer surface of the ACF were coated with F-PU via the urethane reaction of the hydroxyl groups (-OH) of the surface of ACF and the isocyanates of F-PU. The successfully fabricated in-and-out F-PU-coated heterogeneous fabric exhibited excellent hydrophobic properties, anti-scratch performance, oil-water separation performance, and bacterial penetration blocking efficiency (>99% for gram negative and gram positive bacteria). Furthermore, the in-and-out-coated ACF exhibited high durability, and retained its bacterial penetration blocking performance after scratch tests.
