Oil or chemical purification is significant not only for industrial safety production but also because it conforms to the principle of sustainable development. In this paper, based on the synergistic concept of superwettability and nanopores sieve effect, a superoleophilic and under-oil superhydrophobic carbon nanotube/poly(vinylidene fluoride-co-hexafluoropropylene) nanofiber composite membrane is prepared via electrospinning, pressure-driven filtration, and chemical vapor modification. The as-prepared membrane with durable mechanical and chemical stabilities achieves separation efficiency higher than 99.9% and high flux up to 632.5 L m h bar for different water-in-oil emulsions. This membrane is highly promising for the petroleum and chemical industries for both product quality improvement and green recycling manufacturing processes.
油或化学净化不仅对工业安全生产具有重要意义，而且符合可持续发展原则。本文基于超润湿性和纳米孔筛效应的协同概念，通过静电纺丝、压力驱动过滤和化学气相改性制备了超亲油和水下超疏油的碳纳米管/聚（偏二氟乙烯-共-六氟丙烯）纳米纤维复合膜。所制备的具有持久机械和化学稳定性的膜在不同的水包油乳液中实现了分离效率高于 99.9%和通量高达 632.5 L m h bar。该膜在石油和化学工业中具有广阔的应用前景，可用于提高产品质量和绿色回收制造工艺。
