摘要

In this paper, the methods for modification of polymeric membranes with Poly (ethylene oxide) (PEO) and Poly (ethylene glycol) (PEG) for CO2 separation is reviewed. PEO-containing membranes considered due to their proper CO2 separation performances and simplicity in fabrication. However, high crystallization tendency and mechanical strength of these PEG-based membranes have limited their applications on commercial scale. Hence, various methods have been proposed to overcome these shortcomings and improve the performance of the membranes, such as blending with other polymers or the formation of new chemical structures by copolymerization and crosslinking. In this paper, the state-of-the-art for the polymeric membranes containing PEO or PEG for CO(2 )separation is investigated and the separation performance of each category is evaluated and finally, future research directions and recommendations in this field are proposed. According to the present study, in general, although the mixed matrix membranes have shown excellent performances for carbon dioxide separations, the ionic liquid containing membranes also have offered high permeability and selectivity than the other types of membranes, and it seems that the MMMs containing Its would be promising for future generation membranes.
