Abstract

Efficient and cost-effective technologies that will enable separation and capture of CO2 are needed. The development of high-performance all-aromatic poly(ether)imide (P(E)I) membranes is attractive as they offer a large degree of design freedom and they are cheap to operate. However, the molecular design rules towards P(E)I membranes that exhibit high selectivity and high permeability with no or little CO2 plasticization are still largely unknown. The main objective of the research presented in this thesis is to understand the structure-property relationships of all-aromatic polyimide- and polyetherimidebased gas separation (CO2/CH4) membranes. In particular, the role of backbone design and how this affects the free volume and gas separation performance of the final membranes.
