A ground breaking polymer blend for CO2/N2 separation KU Leuven
© 2018 Elsevier Ltd. All rights reserved. The commercial polyetherimide sulfone polymer Extem was blended with polyethersulfone (PES) to achieve a new, highly selective membrane for CO2/N2 separation in order to allow for a breakthrough in carbon capture applications. The miscibility and molecular interaction between PES and Extem for blend compositions 80/20, 50/50 and 20/80 w/w were evaluated. Differential Scanning Calorimetry showed that of ...
