Highly durable and sustainable heterogeneous fabric using in-and-out fluorinated urethane coating for elimination of bacteria and oil–water separation

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