Abstract
In this work fullerene (Fullerene) nanoparticles, carboxylated multi-walled carbon nanotubes (MWCNTs), and fullerene- carboxylated multi-walled carbon nanotubes hybrid (Fullerene-MWCNTs), were used as the dispersed phase in polyethersulfone (PES) matrix to form mixed matrix membranes (MMMs). Low molecular weight para-nitroaniline (pNA) was used as the functionalization agent. Nanoparticles were specified using Fourier Transform Infrared (FTIR) spectroscopy and Transmission Electron Microscopy (TEM). The membranes were formed by the wet phase inversion method and their properties were determined by Differential Scanning Colorimetry (DSC) and Field Emission Scanning Electron Microscopy (FESEM). Gas permeation and separation performance of the membrane samples were also tested via a constant pressure system utilizing pure CO2 and CH4 gasses. The permeation test results showed that the PES/pNA-MWCNTS 0.5 wt% sample has the highest selectivity (42.05) among other samples. Also, this sample showed the desired amount of CO2 permeance (12.86 GPU).
