摘要

Abstract

Nowadays

mixed matrix membranes (MMMs) have considered by many researchers to overcome the problems of polymeric membranes. In addition

molecular dynamics (MD) and Monte Carlo (MC) simulation Methods are suitable tools for studying transport properties and morphology in MMMs. For this purpose

in this study using material studio 2017 (MS) software

the transport properties of CO

and N

in Pebax

Psf neat Pebax/Psf composite and Pebax/Psf composite filled with ZIF-90 particles have been investigated. By adding Psf to Pebax matrix

the selectivity of CO

/CH

and CO

gases has significantly increased. In addition

adding ZIF-90 particles to the Pebax/Psf composite increased the permeability of CO

and N

compared to neat and composite membranes. The morphological properties of the membranes

such as the fractional free volume (FFV)

radial distribution function (RDF)

glass transition temperature (

)

X-ray diffraction (XRD) and equilibrium density have calculated

and acceptable results have obtained.
