Abstract

Abstract: For the investigation of different solvents’ influence on structure and performance of PPESK carbon membranes, PPESK derived films for gas separation were prepared with NMP，CHCl3，DMAc and TCE. The chemical structure, microstructure and gas separation properties of these membranes were characterized by FTIR、TG、XRD and gas permeation tests. The result indicated that the main cause of gas permeation and selectiveity was the different carbon structure，pores and flexility of carbon membranes induced by the variation discipline during preoxidation and carbonization in consequence of solubility, boiling point, volatility and content of solvents.

Key words: Poly(phthalazinone ether sulfone ketone), carbon membrane, solvents, structural performance, gas separation
