Abstract
Poly(ethylene oxide)- (PEO-) based block copolymer membranes have great potential for use in CO2 separation because of their excellent selectivity and moderate permeability. Whereas numerous studies have focused on the permeation performance of such membranes, the influence of the microphase-separated structures on the gas transport is not well understood. This study examined the phase structure of PEO-polyamide (PA) (commercial name, Pebax) block copolymer membranes by scanning probe microscopy (SPM) imaging and thermal analysis. The membranes with the irregular and more disordered phase-separated structure, such as Pebax-1074 membranes, that had longer PA chains and were made using a faste..
