“…Therefore, there is an urgent need to reduce the CO 2 emissions and the CO 2 concentration in the atmosphere. Carbon capture and storage (CCS) is one of the most important technology used to reduce CO 2 emissions [2,6]. In comparison to the traditional CO 2 separation technologies e.g., absorption, adsorption, and cryogenic distillation, membrane technology possesses many advantages such as simple process operation, small footprint, energy efficiency and cost effectiveness [1,[5][6][7].…”

The CO2 separation from flue gas based on membrane technology has drawn great attention in the last few decades. In this work, polyetherimide (PEI) hollow fibers were fabricated by using a dry-jet-wet spinning technique. Subsequently, the composite hollow fiber membranes were prepared by dip coating of polydimethylsiloxane (PDMS) selective layer on the outer surface of PEI hollow fibers. The hollow fibers spun from various spinning conditions were fully characterized. The influence of hollow fiber substrates on the CO2/N2 separation performance of PDMS/PEI composite membranes was estimated by gas permeance and ideal selectivity. The prepared composite membrane where the hollow fiber substrate was spun from 20 wt% of dope solution, 12 mL/min of bore fluid (water) flow rate exhibited the highest ideal selectivity equal to 21.3 with CO2 permeance of 59 GPU. It was found that the dope concentration, bore fluid flow rate and bore fluid composition affect the porous structure, surface morphology and dimension of hollow fibers. The bore fluid composition significantly influenced the gas permeance and ideal selectivity of the PDMS/PEI composite membrane. The prepared PDMS/PEI composite membranes possess comparable CO2/N2 separation performance to literature ones.

The development of thin layer on hollow-fiber substrate has drawn great attention in the gas-separation process. In this work, polydimethysiloxane (PDMS)/polyetherimide (PEI) hollow-fiber membranes were prepared by using the dip-coating method. The prepared membranes were characterized by Scanning Electron Microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), and gas permeance measurements. The concentration of PDMS solution and coating time revealed an important influence on the gas permeance and the thickness of the PDMS layer. It was confirmed from the SEM and EDX results that the PDMS layer’s thickness and the atomic content of silicon in the selective layer increased with the growth in coating time and the concentration of PDMS solution. The composite hollow-fiber membrane prepared from 15 wt% PDMS solution at 10 min coating time showed the best gas-separation performance with CO2 permeance of 51 GPU and CO2/N2 ideal selectivity of 21.

“…A coordinate bond was formed between a copper ion and the ligand to obtain the desired MOF. The free carboxylic acid groups in this MOF, which were introduced by pre-modification, can selectively recognise Cl(H 2 O) 4 clusters. Thus, specific recognition of molecules can be performed with this MOF.…”

Metal-organic frameworks (MOFs) refer to porous coordination materials that are formed from the assembly of metal ions and organic ligands. They have unique features, such as a large specific surface area, multiple active sites, easy functionalisation, and adjustable biocompatibility. MOFs have recently been widely used in the field of biomedical engineering owing to their unique structures and properties. This has enabled them to replace traditional materials and effectively address several problems. Through continuous development, MOF-based biomaterials have been remarkably improved by clarifying the relationship between MOF structures and properties. As a result, they are being extensively studied in the fields of chemical and material science. MOF-based biomaterials can meet the growing demands for efficient materials in biomedical applications. This review first discusses the basic structure of MOFs, followed by their preparation and functionalisation methods. The biomedical applications of MOF-based biomaterials in the fields of antibacterial activity, tumour therapy, skin repair, and bone repair are then summarised. Finally, challenges and future perspectives in the biomedical applications of MOF-based biomaterials are outlined.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
