In this paper, a novel, simple, but efficient method is reported to lower pressure drop and meanwhile maintain high filtration efficiency of superoleophobic filters for oil aerosol filtration. By close attachment of a thin oil‐guiding fibrous layer to the front surface of a superoleophobic filter, the pressure drop at pseudostatic state can be reduced by 20%. Such a remarkable reduction in filtration resistance is originated from the capillary effect of the oil‐guiding fabric, and pore size within the guiding fabric also played a role. This novel material may be useful for the development of high efficiency, low energy‐consumption coalescing filters for various applications.

超疏油性过滤器：导油织物的前部安装提高了过滤性能

本文报道了一种新颖，简单但有效的方法，该方法可降低压降，同时保持用于油雾过滤的超疏油性过滤器的高过滤效率。通过将薄的导油纤维层紧密附着到超疏油过滤器的前表面，可以将假静态下的压降降低20％。滤油阻力的显着降低是由于导油织物的毛细作用引起的，并且导流织物内的孔径也起了作用。这种新颖的材料可能有助于开发适用于各种应用的高效，低能耗的聚结过滤器。
