摘要

Abstract

The results of molecular dynamics (MD) simulations on transport process of CO

and CH

gases in poly(ether-bamide) (PEBAX)/nanosilica membranes are discussed. The diffusion coefficients for CH

and CO

gases at 6 cases with different amounts of nanosilica loading in the simulation boxes are presented. The results show that diffusion coefficients for CO

gas in all cases are larger than those for the CH

one. Moreover 10% nanosilica loading case shows maximum effects on diffusion coefficients and improves them by more than 68% and 157% for CO

and CH

gases

respectively. Additionally

the results of 3-D Cartesian trajectories and displacements curves are presented and the jumping attempt of CO

is significantly more than that of CH

. Due to the rubbery state of PEBAX membranes in ambient temperature

the results confirm that channel lifetimes are very short and then back diffusion is not observed for this polymer.
