    摘要: A method of manufacturing a filled polymeric membrane includes a first step of preparing a filler suspension having a solvent for a glassy polymer and nanometer-sized particles. The nanometer-sized particles in the filler suspension are aggregated in aggregates having an average aggregate size in the range between 50 nm and smaller than 200 nm. In a following step, the glassy polymer is added to the filler suspension to obtain a polymer suspension. Next, the glassy polymer is dissolved in the polymer suspension. In a next step, the polymer suspension is cast on a substrate, followed by a step of removing the solvent. A filled polymeric membrane includes aggregates of nanometer-sized filler particles. The membrane is used in pervaporation and nanofiltration.
