“…This was attributed to the pore sizes of MgO nanoparticles which were larger than the sizes of gas molecules [247] . Similar fi nding was also reported by Freeman and coworkers, that the higher loading of MgO nanoparticles increased void volumes and gas permeabilities of MMMs [248] . The CO 2 permeability of poly(1-trimethylsilyl-1-propyne) MMM with 40% MgO loading was 4.5 times higher than that of unfi lled polymer fi [248] .…”

Over the past two decades, membrane technology has attracted tremendous attention at CO 2 separation from other gases, which has shown great potential to significantly improve energy efficiency and reduce cost associated with processes. The membrane structures and chemistry properties greatly affect their CO 2 separation performances, including selectivity and permeability. In recent years, there has been significant progress in the development of CO 2 -selective membranes. This chapter reviewed the recent activities relating to the fabrication and separation performances of polymeric, inorganic and mixed-matrix membranes for CO 2 separation purposes.

Gas transport behavior of mixed-matrix membranes composed of silica nanoparticles in a polymer of intrinsic microporosity (PIM-1) Ahn, Juhyeon; Chung, Wook-Jin; Pinnau, Ingo; Song, Jingshe; Du, Naiying; Robertson, Gilles P.; Guiver, Michael D.This article appeared in a journal published by Elsevier. The attached copy is furnished to the author for internal non-commercial research and education use, including for instruction at the authors institution and sharing with colleagues. Recently, high-free volume, glassy ladder-type polymers, referred to as polymers of intrinsic microporosity (PIM), have been developed and their reported gas transport performance exceeded the Robeson upper bound trade-off for O 2 /N 2 and CO 2 /CH 4 . The present work reports the gas transport behavior of PIM-1/silica nanocomposite membranes. The changes in free volume, as well as the presence and volume of the void cavities, were investigated by analyzing the density, thermal stability, and nano-structural morphology. The enhancement in gas permeability (e.g., He, H 2 ,O 2 ,N 2 , and CO 2 ) with increasing filler content shows that the trend is related to the true silica volume and void volume fraction. Crown

“…Despite its direct applicability to such structures, it appears that this expression is not popular in the membrane literature. On the contrary, a modified Bruggeman approach [18,19] that suggests the use of an asymmetric expression and is valid for dense dispersions, has enjoyed use in the membrane literature [20][21][22][23]. Specifically, the equation:…”
