Predicting Gas Permeability through Mixed-matrix Membranes Filled with Nanofillers of Different Shapes

Gas permeation through mixed-matrix membranes (MMMs) filled with fillers of non-spherical shapes can be theoretically predicted through different analytical models on the basis of ideal (two-phase) or non-ideal (three-phase) morphology of membrane structure. The predicting capability of different mo...

Description
Summary:Gas permeation through mixed-matrix membranes (MMMs) filled with fillers of non-spherical shapes can be theoretically predicted through different analytical models on the basis of ideal (two-phase) or non-ideal (three-phase) morphology of membrane structure. The predicting capability of different models was evaluated by comparing the estimated carbon dioxide (CO 2 ) permeance through composite membranes against the available experimental permeation data of Ultrason®/ZIF-300, poly(ethersulfone)/functionalized-CNTs and Matrimid®/graphene oxide hybrid membranes. Experimental-to-theoretical discrepancy in CO 2 permeability for composite membranes containing fillers of different shapes was determined by calculating percentage average absolute relative error (AARE%) for each model. General order of data fitting for different models while considering typical values of morphological parameters was found as: Maxwell
