Intrusion of PDMS top layers in porous supports

Abstract The intrusion of polydimethylsiloxane (PDMS) top layers in Zirfon ® (polysulfone filled with zirconium oxide) and polyvinylidenefluoride (PVDF) asymmetric support layers is studied. Parameters such as the porosity of the support, the concentration of the coating solution, the presence of additives in the support during coating and pre-wetting of the supports are investigated with spectroscopical techniques, thermal analysis and pervaporation.
