Liquid-phase extraction is widely used in the chemical industry. Traditional extracting routes always involve multiple procedures, need a large floor space, and have long operating time. “Continuous in situ extraction” that can conduct a real-time integration of solutes extraction and solvents separation simultaneously would be of great significance. Superwettable materials offer us a good choice to separate different immiscible solvents; herein, we achieve continuous in situ extraction of multiphase complex systems by using a porous polytetrafluoroethylene membrane with nanostructure-induced superwettability. It realizes a rapid, selective, and efficient real-time removal of various extracting agents during a continuous process due to their wetting differences. Compared with traditional extraction, our route shows a distinct superiority on saving operating time, enhancing liquid recovery, and simplifying procedures, while still retaining high extracting performance. In addition, our membrane possesses excellent durability even after long-term work in harsh chemical environments or under strong mechanical impacts. Thus, we believe that it will provide a potential alternative for current industrial extractions.

基于微/纳米结构的超湿膜对多相复杂系统的连续原位萃取

液相萃取在化学工业中被广泛使用。传统的提取路线总是涉及多个步骤，需要较大的占地面积，并且需要较长的操作时间。能够同时进行溶质提取和溶剂分离的实时整合的“连续原位提取”将具有重要意义。超湿性材料为我们提供了一个很好的选择，可以分离不同的不混溶溶剂。在这里，我们实现了原位连续通过使用具有纳米结构诱导的超润湿性的聚四氟乙烯多孔膜萃取多相复杂体系。由于它们的润湿差异，它可以在连续过程中快速，选择性，高效地实时去除各种萃取剂。与传统提取相比，我们的路线在节省操作时间，增强液体回收率和简化流程的同时，仍保持了较高的提取性能，显示出明显的优势。此外，即使在恶劣的化学环境中或在强烈的机械冲击下长期工作后，我们的膜仍具有出色的耐久性。因此，我们相信它将为当前的工业提取提供潜在的替代方法。
