Zusammenfassung:Presented is a method for preparing a gas separation membrane system. This method involves depositing a membrane layer of gas-selective metal upon a tubular porous support followed by annealing the resulting layer of gas-selective metal. The resulting annealed membrane layer of gas-selective material is polished under a controlled polishing condition with an abrading medium that includes a structured abrasive article comprising a backing having bonded thereto an abrasive layer comprising a plurality of shaped abrasive composites that comprise abrasive grains dispersed in a polymeric binder. Another layer of gas-selective metal is then deposited upon the tubular porous support. The cycle of annealing, polishing and depositing is repeated through one or more cycles until a leak-tight membrane system is provided.
