The effect of TiO2 nanoparticles on gas transport properties of Matrimid5218-based mixed matrix membranes

Polymeric mixed matrix membranes containing zeolites as a filler for gas separation applications: A review

“…Alternative approach to obtain MMMs would consist in the use of hollow zeolite sphere (HZS) particles. The obtained HZS-MMMs would benefit from the advantages of zeolites, as microporous and crystalline molecular sieves, (as well as the properties of spherical filler that would minimize agglomeration and hence improve dispersability and interaction with the polymer phase [57,157].The first intention of using HZS as inorganic filler in MMMs for gas separation has been reported by Zornoza et al [57], showing that the separation performance of gas mixtures H 2 /CH 4 , CO 2 /N 2 and O 2 /N 2 was significantly improved due to the spherical shape that has contributed to good dispersion and well filler-polymer contact as well as the hollow nature to allow fast flow and increase the gas permeability [42,143].…”

“…Metal organic frameworks (MOF) [20][21][22][23][24][25][26][27][28], zeolitic imidazolate frameworks (ZIFs) [29][30][31][32][33], activated carbon [15,34], carbon nano tubes [35][36][37][38][39], titanosilicates [40,41], and ordered mesoporous silica [11,[42][43][44][45][46][47] are other types of porous materials that have been applied as the dispersed phase in mixed matrix membrane fabrication. Silica [42,[48][49][50][51][52][53], TiO 2 [42,[54][55][56][57], and fullerene (C60) [58] are the most conventional impermeable inorganic particles used for the MMMs fabrication.…”

“…The incorporation of metal oxides normally exerts similar effect as that of impermeable silica particles in which the alteration of gas transport behaviour in such MMM is the result of chain packing disruption and nanoscale agglomeration of nanoparticle in polymer matrix. Upon the incorporation of TiO 2 into the polymer matrix, the dispersion of these nanoparticles was varied depending on the amount of loading [42,57].…”

Enhanced CO 2 /CH 4 separation properties of asymmetric mixed matrix membrane by incorporating nano-porous ZSM-5 and MIL-53 particles into Matrimid ® 5218

“…In MMMs, polymers are used as continuous phases with dispersed inorganic particles as fillers. These membranes combine high separation properties of inorganic materials with flexibility and easy fabrication of polymers (Junaidi et al, 2014a(Junaidi et al, , 2014bAbedini et al, 2012;Moghadam et al, 2011). Zeolites are used frequently as dispersed phase in MMMs.…”
