Membrane-based separations can lessen the environmental effect of conventional techniques while increasing energy efficiency. Conventional adsorbents, on the other hand, enclose the majority of their functional sites in their dense structures, which causes problems with limited selectivity and adsorption capacity. By top-down method, based on the molecular structure and properties of artemisinin (Ars), a three-dimensional porous basswood membrane and a Metal-organic framework (MOF)-based modified layer were used as a dot-matrix initiator. The combination design of hydrophobic bond and complex bond interaction synergistic imprinting strategy was used to construct high density and high selectivity Ars molecularly imprinted polymers (MIPs) on the membrane, thus achieving the preparation of MOF-initiated imprinted self-supporting basswood membranes (MPIBSMs). When combined with the superhydrophilicity of the TiO 2 modified layer and the numerous accessible imprinting sites that MOF previously grown in situ on basswood provided, the resulting MPIBSMs displayed good adsorption capacity (81.2 mg g−1), selectivity coefficient (greater than 4.9), and ultrahigh water flux, eliminating the "trade-off" effect between membrane flux and selectivity. Additionally, the MPIBSMs are synthesized in a straightforward, pollution-free manner. Additionally, MPIBSMs were created in a green way. Finally, the aforementioned experimental findings and the environmentally sound synthetic technique imply that MPIBSMs have a wide range of possible applications in several fields, including environmental protection and selective separation. [Display omitted] • The MOF modified layer was used as the initiator for imprinting polymerization. • A cooperative imprinting strategy for multiple non-covalent interactions was designed. • TiO 2 modification improved the hydrophilicity and antibacterial properties of the MPIBSMs. • The accurate identification and selective isolation of artemisinin were realized.

Herein, according to the polydopamine (PDA)-based imprinting and thermal-induced imprinting methods, we reported on the development and applications of double-layer-imprinted mixed matrix membranes (DI-MMMs) through a dual-imprinted strategy, thereinto, the tetracycline (TC), one of the pollution-intensive pharmaceutical and personal care products, was chosen as template molecule. As to the first-TC-imprinted layer, the blended PDA-based TC-imprinted activated carbon (AC) and SiO 2 were both used for the preparation of membrane. Next, κ-carrageenan-modified graphene oxide (GO) nanosheets would be regarded as the surface-loaded layer to support the thermal-induced imprinting synthesis (second-TC-imprinted layer). Importantly, high adsorption capacity at around at 106.44 mg/g and fast adsorption rate (within 60 min) had been successfully obtained. Importantly, permselectivity rates (β) of our imprinting membranes were obtained as 3.60, 3.33 and 3.51, respectively. Overall, based the practical selective separation and scalability analysis, we believed that the as-prepared DI-MMMs with high-intensitive recognizability and permeability of template molecule would provide a possibility for breaking the permeability-selectivity trade-off of molecularly imprinted membrane materials. Porous&permeable double-layer-imprinted mixed-matrix membranes, in which TC was used as template molecule, were constructed based on our newly-developed synergetic synthesis strategy of double-TC-imprinted layers. [Display omitted] • PDA-based imprinting & thermal-induced imprinting methods were first proposed. • Double-layer-imprinted mixed-matrix membrane structures was successfully constructed. • Well-designed TC-imprinted membrane was applied as selective separation device. • High-performance flux and permselectivity of MIMs were obtained simultaneously.
