Vermeiren, J. Moreels, R. Leysen] The composite Zirfon® membranes are made of a polysulfone network and zirconium oxide as an inorganic filler. These composite membranes are actually being used for a variety of ultrafiltration purposes and as separator material in different types of electrochemical cells. The main techniques which have been used for the characterization of the porous structure of these membranes are mercury intrusion porosimetry, scanning electron microscopy (SEM) and gas adsorption. As a major result it has been observed that the amount of ZrO2 which is present in the membrane plays a dominant role: the structure of a composite Zirfon© membrane is completely different from the structure of a pure polysulfone membrane. The membrane becomes denser with increasing amounts of ZrO2. There is also a strong indication that ink-bottle shaped pores are present and that their volume reduces with increasing amounts of ZrO2.
