The porous structure was prepared with polyether ether ketone (PEEK) and polyphenylene sulfide (PPS), which had excellent solvent resistance and thermal resistance as the mixed polymers, and diphenyl ketone as the diluent. The possibility of forming porous structure and the control of porous structure were investigated in the blended system. The effecting factors including the different weight ratios of PEEK/PPS and the total concentration of polymers on the porous structure are discussed, and the two‐step phase separation process brings forward the formation of membrane in this system. © 2007 Wiley Periodicals, Inc.
