Abstract
- Click-Chemistry synergic MXene-functionalized flexible skeleton membranes achieved high-efficiency selective separation to artemisinin. [Display omitted] • Transport to specific molecule was achieved assisted by MXene laminated structure. • High stability for perm-selectivity of MIMs in mobile phase was achieved. • Click-chemistry drove to build dot-matrix imprinting units. • MIMs showed excellent antibacterial properties and sustainable reusability. Membrane-based technology with accurate-recognition and specific-transmission has been regarded as one of the most promising strategies in environmental protection and energy conservation. However, membrane technique still faces challenges of "trade-off effect" between high selectivity and permeation flux within organic-aqueous mixed matrix. Here, well-intergrown click-chemistry synergic MXene-functionalized flexible skeleton membranes has been prepared in this strategy, enabling size-exclusion&structure selectivity by uniform location array imprinting unit and transport performance towards specific medicinal molecules of artemisinin (Ars). The well-assembled ultrathin cascade-type MXene layer guarantees the narrow interlayer nanochannels and the flexible skeleton modified mesoporous SiO 2 nanoparticles provide active reaction platform for the construction of selective recognition space. The resulting membranes demonstrated outstanding selective separation performance with permeability factor that artesunate (Aru) /Ars and dihydro-artemisinin (d -Ars) / Ars of 3.17 and 2.89 and permeation flux of 1173.25 L·m−2·h−1·bar−1. Besides, combined with antibacterial durability, recycling performance, high separation performance in mobile phase stability of CMFMs, it is anticipated that this work hopefully opens a new avenue for efficient chiral separation to medicinal molecules, exhibiting broad potential for practical application.
