“…Membranes infused with a strongly interacting trapping phase that is immiscible with the separated phase have been designed to more selectively regulate mass transfer. 11–14 Inspired by the Nepenthes pitcher , filling an extremely low surface energy liquid such as perfluoropolyether (PFPE) into pores of hydrophobic membranes, including polytetrafluoroethylene, poly(vinylidene fluoride), and polypropylene (PP) membranes, created a gated separation system, which can separate three-phase air–water–oil mixtures. 14 Importantly, these slippery liquid-infused porous surfaces (SLIPS) show sustainable antifouling ability when operating in harsh environments.…”
