Abstract

Advanced separation membranes are crucial for water-energy sustainability, but the synthesis of highly efficient membranes with excellent durability and antifouling ability remains highly challenging. Inspired by the natural mineralization processing of biominerals, ultrarobust and antifouling mineralized membranes were synthesized via heterophase interface engineering. At the heterophase interface, phosphate ions and tannic acid (TA) in the coagulation bath (nonsolvent phase) encounter the metal ions in the casting solution (solvent phase) for biomimetic mineralized membrane growth. Metal ions, as sites of mineralization nucleation, combine with phosphoric acid to form minerals, and TA regulates the mineralization process by chelating with metal ions. The mineralized membrane exhibited an exceptional permeance recovery rate (up to 99%) and modulus (4.1-fold higher than that of the control membrane), which were recorded for pressure-driven filtration tolerance. This study paves the way for the in situ synthesis of advanced membranes and materials for water treatment, catalysis, and solar evaporation.

异相界面工程制备超粗仿生矿化膜

先进的分离膜对水-能源可持续性至关重要，但合成具有优异耐用性和防污能力的高效膜仍然具有很高的挑战性。受生物矿物自然矿化过程的启发，采用异相界面工程技术合成了超抗菌防污矿化膜。在异相界面，混凝液（非溶剂相）中的磷酸盐离子和单宁酸（TA）与铸造液（溶剂相）中的金属离子相遇，进行仿生矿化膜的生长。金属离子作为矿化成核的位点与磷酸结合形成矿物，TA通过与金属离子的螯合作用调节矿化过程。矿化膜表现出优异的渗透回收率（高达99%）和模量（比对照膜高4.1倍），记录了压力驱动的过滤耐受性。这项研究为原位合成用于水处理、催化和太阳能蒸发的先进膜和材料铺平了道路。
