Development of Poly(Amidoamine) Dendrimer/ Poly(Ethylene Glycol) Hybrid Membranes for CO2 Capture at Elevated Pressures

A compatible crosslinker (CPC) was used to prepare the composite membrane with a thin selectivity layer to enhance CO2 permeance. An isopropyl alkyl hindered amine IAM, tertiary amine TA1 and TA2 were added to the formation solution of membrane for investigating the effect of additive on CO2 separation performance.
