Abstract

The Influence of Embedding Different Loadings of MWCNTs on the Structure and Permeation of CAB Blended Membrane

Highlights

  • One of the major issues concerning the international community in recent years is the increase of greenhouse gas emissions into the atmosphere, carbon dioxide (CO2)

  • This study aims to synthesise an excellent matrix membrane (MMM) with high separation performance by studying the effects of incorporating different amounts of multi-walled carbon nanotubes (MWCNTs) fillers into the cellulose acetate butyrate (CAB) blended membrane

  • The formed clusters on the membrane surface were due to the changes in the membrane’s phase separation kinetics and long-term dope stability caused by the incorporation of the MWCNTs-P into the CAB.[17]

Summary

Introduction

One of the major issues concerning the international community in recent years is the increase of greenhouse gas emissions into the atmosphere, carbon dioxide (CO2). 90% of the total membranes installed today are made of nine polymer organic materials such as polysulfone, polyaramide, poly(vinylidene chloride) (PVDC), poly(furfuryl alcohol) (PEA), polyacrylonitrite (PAN), phenolic resins, poly (phenylene oxide), cellulose acetate (CA) and cellulose acetate butyrate (CAB). These materials have a tendency of producing membranes with high permeability and selectivity.[3] With reference to the CAB membrane, it was first communalised in 1938. The incorporation of MWCNTs led to a noticeable increase in the membrane free volume.[9]
