Molecularly imprinted membranes (MIMs) with sufficient and even-distributed recognition sites that can break the permeability-selectivity trade-off phenomenon are desirable in chemical field of selective separation. Herein graphene oxide (GO)/TiO 2 -loaded nanocomposite fibrous membranes were prepared by developing two kinds of tetracycline (TC)-imprinted systems in the same MIMs-based material. Thereinto, polydopamine-based and sol-gel-based imprinting processes were applied to the synthesis of GO/TiO 2 -loaded dual-imprinted mixed matrix membranes (GT-DIMs). The as-prepared GT-DIMs encompassed innovative GO/TiO 2 -based nanocomposite fibrous channels and two kinds of TC-imprinted systems, and critical comparisons regarding the fluxes, rebinding capacities and permselectivity were provided and studied. Importantly, dual-imprinted system of GT-DIMs could not only allow for largely enhanced rebinding result (70.63 mg/g) and fast adsorption equilibrium rate within 30 min, but also facilitate the high permselectivity of TC in complex separation systems and lab-simulated wastewater samples. The permselectivity factors were all around 5.0, which strongly demonstrated the efficiently selective recognition and separation performance of GT-DIMs. Overall, based on testing results of practical separation and scalability, excellent structural stability and separation continuity had been successfully obtained for selective separation applications of pollutants., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Inc.

Here, the graphene oxide (GO)/SiO 2 -loaded dual-imprinted membranes (GS-DIMs) were constructed based on the self-polymerization imprinting technique of dopamine, in which a twice polydopamine (PDA)-based imprinting strategy had been successfully developed to obtain the three-dimensional nanocomposite membrane-based separation system. Meanwhile, the pollution-intensive antibiotics of tetracycline (TC) was used as template molecule throughout the GS-DIMs synthesis, and the dopamine molecules were simultaneously used as functional monomer and cross-linking agent during the twice polydopamine (PDA)-based imprinting processes. Therefore, dual-TC-imprinted sites had been prepared based on the as-designed dual imprinting processes, the as-prepared GS-DIMs-based separation system with dual-TC-imprinted structures could not only allow for the largely enhanced rebinding result of 65.61 mg/g and faster adsorption equilibrium rate within 20 min, but also facilitate the permselectivity performance from TC-based complex separation system and mimetic water sample. Importantly, we demonstrated the applications and effects of the dual-imprinted membrane-based separation materials to selective rebinding and separation of TC from complex solution systems and mimetic water samples. The as-obtained permselectivity factors (β) around 4.0 strongly illustrated the efficiently selective separation ability and high-intensitive recognizability of TC than any other non-template molecules based on our GS-DIMs-based separation system. Overall, the as-designed GS-DIMs had great potential for selective separation applications and provided critical comparisons based on the as-achieved excellent rebinding and permselectivity performance, which encompassed innovative GO/SiO 2 -loaded nanocomposite and PDA-based dual-TC-imprinted system., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Inc.

Three-dimensional (3D) basswood materials, for the first time, were successfully used for the construction of rare-earth Nd(III)-imprinted nanocomposite membranes. Herein, polydopamine (PDA)-modified layers could be initially synthesized on basswood surfaces. After the double-bonded modification procedure, the 3D wood-based ionic imprinted membranes (3DW-IIMs) system was finally accomplished by developing a re-modified two-step-temperature free radical polymerization process. The as-design PDA@basswood surface structure was first proposed and applied as imprinting-initiated factors for the preparation of Nd(III)-imprinted sites. Importantly, excellent rebinding capacity (120.87 mg g -1 ), adsorption kinetics and permselectivity coefficients (more than 10) were achieved successfully. Furthermore, an important research result had also been found that the PDA-modified layers caused significant promotions to the rebinding capacities of the as-prepared 3DW-IIMs, that is to say, more and more Nd(III)-imprinted sites could be synthesized because of the PDA-modified surfaces. The as-obtained selective rebinding and separation results together with the green natural wood-based materials strongly demonstrated that our synthesis methodology of 3DW-IIMs had great potential for applications in various fields of rare earth separation, chemical industry, and environment protection., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Inc.

Inspired by the biomimetic modification strategy of dopamine self-polymerization technique, molecularly imprinted nanocomposite membranes (MINCMs) with thermo-responsive rebinding and separation performance were synthesized and evaluated. Herein, the Au/SiO 2 -based multilevel structure had been successfully obtained onto the polydopamine (pDA) modified membrane surfaces. Afterward, the poly(N-isopropylacrylamide)-based biomolecule-imprinted sites were adequately constructed by developing a photoinitiated atom transfer radical polymerization (pATRP) imprinting strategy using the high-biocompatible ovalbumin (Ova, pI 4.6) as template molecule. Therefore, thermo-responsive 'specific recognition sites' toward Ova were then achieved on the as-prepared MINCMs after the well-designed imprinting process. When the external temperature was set at 37 °C, excellent ovalbumin rebinding capacity (33.26 mg/g), selectivity factor (3.06) and structural stability were obtained. Importantly, as to the controllable biocompatibility research of this work, the bare glass and Ova-bound-MINCMs (the MINCMs were bound with Ova) showed basically the same cell adhesion behaviors and viability, indicating the excellent biocompatibility of the Ova-bound-MINCMs. Additionally, efficient and rapid regulation of cell adhesion/detachment on ovalbumin-bound MINCMs could be still obtained even after 10 cycles of temperature-switch process, which indicated that the as-prepared MINCMs had strong ability to work under high intensity and long continuous operation., Competing Interests: Declaration of Competing Interest The authors declared that there is no conflict of interest., (Copyright © 2020 Elsevier Inc.
