N2 - Membranes with amphiphobic properties have shown significant advantages in the filtratimon of oily fumes, yet achieving stable, large-scale production of composite amphiphobic membranes still poses significant challenges. Herein, we present a scalable approach for the development of amphiphobic coatings for creating asymmetrically structured expanded polytetrafluoroethylene/polyphenylene sulfide (ePTFE/PPS) composite membranes. By adopting spray coating and UV curing, the amphiphobic coatings constructed on the ePTFE and PPS sides exhibited contact angles of 149° and 157° for corn oil and hexadecane, respectively. During a 100-h oil mist filtration test, the membrane maintained an oil interception rate above 99.7 %, and the filtration pressure drop decreased by 49 % compared with that of the original membrane. Our scalable manufacturing method creates an amphiphobic design that excels in liquid drainage, making it perfect for oil mist filtration with composite membranes, which is suitable for the industrial fabrication of amphiphobic gas purification membranes.
