Recent development in polymer/montmorillonite clay mixed matrix membranes for gas separation: a short review

Polymer/clay mixed matrix membranes (MMMs) have piqued attention in recent years over pure polymer membranes due to their unique characteristics, such as flame resistance, mechanical capabilities, gas barrier qualities and thermal properties. This article reviews the recent ten years of literature on polymer/montmorillonite (MMT) clay-based MMMs preparation mechanism, morphology and their potential for gas separation. In addition, the MMT clay morphology, possible clay nanostructure formation after mixing in the polymer matrix as well as the different fabrication types of polymer/MMT clay MMMs were discussed. Eventually, this review article was briefly proposed the future direction in polymer/MMT clay membrane preparation techniques to further develop the performance of montmorillonite MMMs in gas separation.
