Wang, Xingguo published the artcileHighly selective membrane for efficient separation of environmental determinands: Enhanced molecular imprinting in polydopamine-embedded porous sleeve, SDS of cas: 7575-23-7, the main research area is polydopamine embedded molecularly imprinted membrane selective separation environmental.
The molecularly imprinted membrane has shown irreplaceable superiority in advanced water treatment, biochem. purification, and in most cases, pretreatment of environmental determinands. However, effective and controllable construction of imprinted sites in membrane-based interpenetrating pores is as yet the significant bottleneck. Herein, the authors proposed a thermally induced strategy on the polydopamine-embedded molecularly imprinted membrane (DEMIM) for enhanced selective separation of Ciprofloxacin (CIP). The porous sleeve was constructed with polyvinylidene fluoride (PVDF), together with the integrated β-cyclodextrin (β-CD) for hydrophilicity and anti-fouling requirements. Based on the thermally induced operation, polydopamine (PDA) embedded in the membrane matrix acted as a secondary reaction platform, effectively improving the interpenetrating-bicontinuous porous morphol. and enhancing the availability of imprinted sites in microchannels. The imprinting polymerization was carried out by the efficient thiol-ene click reaction, which was investigated in depth by d. functional theory (DFT) calculations The impressive relative separation factor (2.33-4.59) and permselectivity (9.50-12.50) indicated the superior availability of DEMIM for the selective separation The remarkable regeneration performance (fluctuation in 8.4%∼10.8%) demonstrated the feasibility of the porous membrane-based sleeve for regeneration of mol. imprinting. The approach and methodologies achieved in this work will potentially promote the development of novel molecularly imprinted membranes for advanced applications.
