The membranes’ role is of supreme importance in the separation of compounds under different phases of matter. The topic addressed here is based on the use of membranes on the gases separation, specifically the advantages of mixed-matrix membranes (MMMs) when using carbon nanotubes as fillers to separate carbon dioxide (CO2) from other carrier gas. MMMs consist of a polymer support with additive fillers to improve their efficiency by increasing both selectivity and permeability. The most promising fillers in the MMM development are nanostructured molecules. Due to the good prospects of carbon nanotubes (CNTs) as MMM fillers, this article aims to concentrate the advances and developments of CNT–MMM to separate gases, such as CO2. The influence of functionalized CNT or mixtures of CNT with additional materials such as zeolites, hydrogel and, graphene sheets on membranes performance is highlighted in the present work.

The present research investigated the utilizing of single and dual-layer flat sheet mixed-matrix membranes (MMMs) for carbon dioxide (CO2) separation. In this research, zeolite 4A is incorporated into a processable polymeric material, polyethersulfone (PES) of MMMs to get the high selectivity and permeability of membrane. Single-layer flat sheet MMMs have been successfully fabricated by adjusting the weight percent of zeolite loading in total solid as the effect of zeolite loading on the performance of MMMs were investigated. It shows that the higher the zeolite loadings, the higher the CO2/CH4 selectivity which is from 1.54 at 0wt % zeolite loading to 3.20 at 20wt % zeolite loading. Besides that, dual-layer flat sheet MMMs was also successfully fabricated with blending of PES and zeolite as selective top-layer and neat PES as sub-layer. Comparison of the results of permeability and selectivity between single and dual layer MMMs with same zeolite loading were studied. The performance of these newly developed dual-layer flat sheet of MMMs gives the best result with CO2/CH4 selectivity for dual layer MMMs is 9.63, tripled of the selectivity of single layer MMMs, 3.20.

Different mixed matrix membranes (MMMs) with various CoBBP nanoparticle loadings were fabricated and tested. Compared to the pure Pebax membrane, the designed MMMs showed both high CO2 permeability and high CO2/N2 selectivity.
