Comparing amine- and ammonium functionalized silsesquioxanes for large scale synthesis of hybrid polyimide high-temperature gas separation membranes
Radmanesh, Farzaneh; Pilz, Monika; Ansaloni, Luca; Peters, Thijs; Louradour, Eric; van Veen, Henk; Høvik, Dag; Hempenius, Mark A.; Benes, Nieck E. (Peer reviewed; Journal article, 2021)PolyPOSS-imide membranes are promising for separating H2 from larger molecules (CO2, N2, CH4) at temperatures up to 300 °C. Their fabrication involves two steps: interfacial polymerization of POSS and 6FDA, followed by ... -
Stability investigation of polyPOSS-imide membranes for H2 purification and their application in the steel industry
Ansaloni, Luca; Saric, Maria; Eric, Louradour; Farzaneh, Radmanesh; Dijkstra, Jan Wilco; Pilz, Monika; Høvik, Dag; Benes, Nieck E.; van Delft, Y; Peters, Thijs (Peer reviewed; Journal article, 2021)In the present work, the high-temperature and long-term hydrothermal stability of novel polyPOSS-imide membranes for high-temperature hydrogen separation is investigated. The polyPOSS-imide membranes are found to exhibit ...
