ABSTRACTThe technology of molecular imprinting permits recognition sites to be inserted into a polymeric material through the polymerisation of a monomer in the presence of a template, or through the dissolution of a preformed polymer in a solution containing the template and then crosslinking or phase inversion so as to obtain the matrix-template complex. This paper will focus on the application of both techniques in the realisation of polymeric membranes with molecular recognition properties in aqueous environments.

In this work, the effect of different phase inversion process on membrane morphology and performance was studied. Polyethersulfone (PES) based polymeric membranes was fabricated containing polyvinylpyrrolidone (PVP) and carboxylic functionalized multiwall carbon nanotubes (MWCNT) as additives and polyethylene glycol (PEG) having a molecular weight 1K, 10K and 35K (Dalton) were used as a model solution for observing the rejection/filteration ability of fabricated membranes. Non-solvent induce phase separation (NIP) and dry-wet phase separation (DWP) method was adopted for membrane synthesis. The FTIR spectra showed that PVP/MWCNT was effectively blended with PES polymer and different phase inversion method led to different internal morphologies of membranes as confirmed by FESEM images. The PEG rejection results suggested that membranes formed by DWP method had approximately double rejection ability than membranes formed by NIP process.

The Matrix

Membrane-based air separation (O2/N2) is of great importance owing to its energy efficiency as compared to conventional processes. Currently, dense polymeric membranes serve as the main pillar of industrial processes used for the generation of O2- and N2-enriched gas. However, conventional polymeric membranes often fail to meet the selectivity needs owing to the similarity in the effective diameters of O2 and N2 gases. Meanwhile, mixed-matrix membranes (MMMs) are convenient to produce high-performance membranes while keeping the advantages of polymeric materials. Here, we propose a novel MMM for O2/N2 separation, which is composed of Matrimid® 5218 (Matrimid) as the matrix, cobalt(II) phthalocyanine microparticles (CoPCMPs) as the filler, and Pluronic® F-127 (Pluronic) as the compatibilizer. By the incorporation of CoPCMPs to Matrimid, without Pluronic, interfacial defects were formed. Pluronic-treated CoPCMPs, on the other hand, enhanced O2 permeability and O2/N2 selectivity by 64% and 34%, respectively. We explain the enhancement achieved with the increase of both O2 diffusivity and O2/N2 solubility selectivity.
