Abstract

Common filter membranes for emulsion separation often require time-intensive preparation with extensive use of chemicals, calling for a fast-processing and eco-friendly alternative. This study introduces a 2-layer stacked nylon meshes treated by surface diffuse atmospheric plasma (SDAP) for rapid and efficient emulsion separation. Commercial nylon mesh exhibits durable super-wetting properties in only 30 s of SDAP treating to be sufficient for effective emulsion separation. Multi-layer stacking further enhances oil-blocking capacity, in which pre-wetted 2-layer meshes achieve over 98% separation efficiency with the flux exceeding 56,000 L·m⁻²·h⁻¹·bar⁻¹ and excellent anti-aging performance with applicability across various emulsions at the same time. The emulsion droplet dynamics within the filter cake reveals the reason for high efficiency, which gives an insight into the research on membrane fouling issues. Furthermore, this work develops SDAP a promising approach for materials treatment for its advantages of fast and green processing, scalable set-up and effectiveness in atmospheric conditions.
