Theoretical models for gas separation prediction of mixed matrix membranes: effects of the shape factor of nanofillers and interface voids

Abstract In this work, a new model is developed by modifying the existing Maxwell–Wagner–Sillars (MWS) to predict gas separation properties of mixed matrix membranes (MMMs). The modified MWS model, for first time, provides simultaneous exploration role nanofillers/matrix interface voids and exact geometrical shape nanofillers in predicting MMMs. To unveil crucial voids, membrane considered three-component system composed polymer as continuous component, dispersed component between two components. Moreover, elucidates ellipsoidal within on MMMs considering factor nanofillers. newly accurately able permeation with lower average absolute relative error ( %AARE ) around 8% compared 30% conventional models such Maxwell Bruggeman Lewis–Nielsen Pal even (∼24%).
