Abstract

A polymeric gas separation membrane utilizing polybenzimidazole based on 4,4′-(hexafluoroisopropylidene)bis(benzoic acid) was prepared. The synthesized membrane has an effective permeating area of 8.3 cm<sup>2</sup> and a thickness of 30 ± 2 μm. Gas permeation properties of the membrane were determined using H<inf>2</inf>, CO<inf>2</inf>, CO, and N<inf>2</inf> at temperatures ranging from 24°C to 200°C. The PBI-HFA membranes not only exhibited excellent H<inf>2</inf> permeability, but it also displayed superior gas separation performance particularly for H<inf>2</inf>/N<inf>2</inf> and H<inf>2</inf>/CO<inf>2</inf>. The permeation parameters for both permeability and selectivity [ PH2 and α(H<inf>2</inf>/N<inf>2</inf>); PH2 and α(H<inf>2</inf>/CO<inf>2</inf>)] obtained for the new material were found to be dependent on trans-membrane pressure difference as well as temperature, and were found to surpass those reported by Robeson in 2008.
