The interaction between polysulfone and ZrO(2) particles is studied as a function of the particle sintering temperature in order to understand the role of ZrO(2) on the formation, morphology, and properties of organo-mineral composite membranes. The adsorption between the sintered ZrO(2) and the constituents of polysulfone, 2,2-diphenylpropane and diphenyl sulfone, is investigated using high-pressure liquid chromatography. The influence of the polymer-ZrO(2) interaction on the flow behavior of the casting suspension is registered via viscoelastic measurements. The organo-mineral composite membranes are formed by immersion precipitation in water, and the resulting membrane morphology is analyzed using high-resolution SEM. The zirconia concentration in the top-layer of the composite structure is determined by XPS. Finally, the link between the polymer-filler interactions, the membrane formation process, and the resulting membrane structure and properties is established.
研究了聚砜与ZrO(2)颗粒之间的相互作用与颗粒烧结温度的关系，以了解ZrO(2)对有机-无机复合膜的形成、形态和性能的作用。使用高压液相色谱法研究了烧结后的ZrO(2)与聚砜的成分2,2-二苯基丙烷和二苯砜之间的吸附作用。通过粘弹性测量记录了聚合物-ZrO(2)相互作用对铸膜悬浮液流动行为的影响。通过在水中浸没沉淀形成有机-无机复合膜，并使用高分辨率扫描电子显微镜分析所得膜的形态。通过X射线光电子能谱确定复合结构顶层中的氧化锆浓度。最后，建立了聚合物-填料相互作用、膜形成过程与所得膜结构和性能之间的联系。
