Summary: Molecularly imprinted polymers (MIPs) are artificial chemical receptors that can selectively recognize template molecules. In this study, caffeic acid was used as a novel functional monomer to synthesize PCA-MIMN for the specific detection of transferrin. The successful synthesis of PCA-MIMN using autoxidation of caffeic acid with HMDA was confirmed. By linking PCA-MIMN with pH-triggered allochroic-graphene oxide, the detection limit for transferrin was greatly improved.

Summary: Molecularly imprinted wax (MIW) spheres were successfully prepared using octadecanoic acid as the functional monomer and wax as the matrix. The MIW spheres displayed remarkable molecular recognition ability and high selectivity towards the template. The as-synthesized MIW could be dissolved in n-hexane or melted by heating for subsequent fluorescence and mass spectrum analysis without the target elution process.

Summary: Thermo-sensitive microgels called PMO-MGs were synthesized and used to prepare composited ultrafiltration membranes with improved surface hydrophilicity and antifouling performance. The PMO-MGs were spherical in shape and had an average diameter of 323±12 nm. The addition of PMO-MGs also imparted thermo-sensitive characteristics to the membranes, with an increase in pure water flux from 369.7 to 618.7 L·m(-2)·h(-1) as the temperature increased from 20 to 45°C.

Summary: Charge-containing polymeric materials were studied for various applications. A series of thermoplastic poly(arylene ether sulfone) (PAES) copolymers with controllable charge contents were prepared. The incorporation of charge density led to a decrease in Tg and mechanical strength, indicating a plasticization effect. The absence of microphase separation in the ion-containing copolymer system further confirmed by electron microscopy and X-ray scattering. The hydrophilicity of the samples was evaluated by water uptake measurements, and the copolymers showed potential for applications requiring a balance between hydrophilicity, processibility, and thermomechanical performance.

Summary: In this study, adamantane groups were introduced into the anion exchange membranes for fuel cells, resulting in a comb-shaped structure. By adjusting the ratio of hydrophobic to hydrophilic segments, the membranes exhibited improved mechanical properties and ionic conductivity. The resulting membranes showed well-defined microphase separation between the hydrophilic and hydrophobic segments, leading to high ionic conductivity and excellent mechanical properties. Therefore, these membranes have great potential for application in fuel cells.

Summary: The study synthesized photoresponsive surface molecularly imprinted polymers (PSMIPs) with controlled nanoshell thicknesses to investigate the effects of polymer shell layer thickness on the separation and purification of 6-O-alpha-maltosyl-beta-cyclodextrin (Mal-beta-CD). The results showed that the removal efficiency and selective capacity of PSMIPs on Mal-beta-CD were strongly correlated to their shell thickness.

Summary: We synthesized ammonium-functionalized copolymers and investigated their potential as sorbents for direct air capture (DAC) of CO2. The copolymers exhibited a moisture-mediated capture and release of atmospheric CO2, with the capacity increasing with the ion exchange capacity (IEC). When the relative humidity was increased, the samples released CO2.

Summary: This paper investigates the inductive effect in a MXene/PES membrane in the electrolyte/membrane/water system, finding that larger ion size and higher concentration lead to a stronger inductive effect hindering ions in the membrane. The study suggests potential applications of the obtained MXene/PES membrane for microsized inductors.
