The beneficial impacts of functional groups of CNT on structure and gas separation properties of PEBA mixed matrix membranes
Source abstract
Abstract
Abstract Incompatibility between filler and polymer chains accompanied by particle agglomeration has a detrimental effect on the performance of mixed matrix membranes (MMMs). To obviate intermolecular forces of different additives, functional groups (-COOH, –NCO, and –NH2) were grafted on the surface of multi-walled carbon nanotubes (MWCNTs) which were then incorporated as fillers in the poly(ether-block-amide) (PEBA) polymeric matrix in the range of 0.1–1 wt% loading. CO2 permeability and ideal CO2/N2 and CO2/CH4 selectivity of MMMs was compared with the neat membrane, and the results revealed favorable enhancement and surpassed CO2/N2 Robeson's upper bound under 4–10 bar in the range of 15–55 °C. Mixed gas separation performance of MMMs, which is of vital importance in industrial applications, was also investigated. The results indicate that MWCNT-NCO created superior grafts with the polymer chains, and MMMs with this additive had a better gas separation performance with high mechanical and thermal stability.
