报告摘要：

Withlow energy consumption and high separation efficiency, membrane-basedtechnologies, such as nanofiltration (NF) and reverse osmosis (RO), have showngreat potential in the field of seawater desalination and wastewater treatment.This presentation reports an ultrafast and universal surface modificationstrategy based on the co-deposition of a macrocycle polyphenol molecule, Noria,and polyethyleneimine (PEI), for which only several seconds are required toobtain a uniform coating. Moreover, thin-film composite (TFC) NF membranes werefabricated by traditional interfacial polymerization (IP) using the Noria–PEIco-deposited coating as the interlayer. Interestingly, the host–guestheterogeneous interaction between anchored Noria on the support surface and aminemonomers in the aqueous phase could significantly alter the IP process andcontribute to a unique nanostrand-hybrid morphology for much improved NFseparation performance. Furthermore, an in situ strategy was utilized tosynthesize the Zeolite imidazolate framework-8 (ZIF-8) nanocrystal onNoria-polyethyleneimine (PEI) modified interlayer surface for the preparationof thin-film nanocomposite (TFN) RO membrane. The permeance of as-fabricatedTFN membrane is up to nearly 3-folder higher than the nascent membrane, whileit still maintains a high rejection towards NaCl. This in situ assemblystrategy reported here could pave a promising way for the fabrication of TFN ROmembranes with other nanomaterials in future.
