文摘

Ageing was studied for different OSN membranes: PEEK, PI and PBI. PEEK membranes withstand thermal annealing under dry conditions. PBI and PI membranes become brittle due to non-equilibrium state. High temperature filtrations were performed in DMF at 140 °C. PEEK membranes performance was stable and consistent up to 4 weeks.
