Abstract
| - The interaction between polysulfone and ZrO2 particles is studied as a function of the particle sinteringtemperature in order to understand the role of ZrO2 on the formation, morphology, and properties of organo-mineral composite membranes. The adsorption between the sintered ZrO2 and the constituents of polysulfone,2,2-diphenylpropane and diphenyl sulfone, is investigated using high-pressure liquid chromatography. Theinfluence of the polymer-ZrO2 interaction on the flow behavior of the casting suspension is registered viaviscoelastic measurements. The organo-mineral composite membranes are formed by immersion precipitationin water, and the resulting membrane morphology is analyzed using high-resolution SEM. The zirconiaconcentration in the top-layer of the composite structure is determined by XPS. Finally, the link between thepolymer-filler interactions, the membrane formation process, and the resulting membrane structure andproperties is established.
