Abstract
The complex formation of epoxidized styrene-butadiene-styrene triblock copolymer (ESBS) with cobalt Schiff base (CoS) in chloroform solution is studied. Facilitated transport of molecular oxygen in ESBS membranes containing various cobalt Schiff bases as fixed carriers of oxygen, and oxygen permeability in ESBS membranes and oxygen-binding ability to the cobalt Schiff base, are studied. Due to the reversible absorption of oxygen by ESBS-CoS, the permeation of oxygen is observable for the lower upstream pressure and can be explained as a dual-mode process. The facilitation is enhanced in the polymeric complexed membrane by the higher oxygen dissociation constant and the lower crystallinity of the ESBS-CoS membrane.
