Poly(amide-12-b-ethylene oxide)/glycerol triacetate blend membranes for CO2 separation

- The Pebax1074/GTA blend membranes with different compositions are prepared.
- Tg of blend membranes fits well with a modified Gordon-Taylor equation.
- The threshold GTA concentration C* is about 40 wt%.
- Pebax1074 mainly dominates the gas permeation properties in zone I.
- GTA strongly influences the gas permeation properties in zone II.
