Fundamental understanding of nano-sized zeolite distribution in the formation of the mixed matrix single- and dual-layer asymmetric hollow fiber membranes

Mixed-Matric Membranes for CO2 and H2 Gas Separations Using Metal-Organic Framework and Mesoporus Hybrid Silicas

“…This is also the order of decreasing permeability in Matrimid ® [18,50]. The values listed in Table 17 are comparable to those previously reported for pure Matrimid ® [18,51,52]. Table 17 also lists all the permeability and ideal selectivity values for the SWNT mixed-matrix membranes at different loadings.…”

Organic-inorganic hybrid membranes in separation processes: a 10-year review

“…Different thermal expansion coefficients of the polymer and particle, repulsive forces between the continuous and dispersed phases, poor polymerparticle adhesion, polymer packing disruption in the vicinity of the inorganic phase and the effects of an elongation stress during fiber spinning are other causes for interfacial void formation (Jiang et al, 2005;Li et al, 2005;Vankelecom et al, 1995). These two interfacial defects may be formed at the porous and impermeable nonporous particle interface when they are added as fillers to the polymer matrix in mixed matrix membranes.…”

Polymer-nanoinorganic particles composite membranes: a brief overview

“…In other words, high elongational draw ratios result in particles moving radially inward to the bore fluid side and radially outward to the outer coagulant side. Jiang et al [45] studied the nano-sized zeolite distribution and the mechanisms of nano-particle movement during the formation of single-and dual-layer membranes. It is indicated that three factors play important roles in determining the nano-particle distribution in the resultant fibers.…”
