Characterization And Physicochemical Modifications Of Polymer Hollow Fiber Membranes For Biomedical And Bioprocessing Applications, Benjamin R. Madsen
Characterization And Physicochemical Modifications Of Polymer Hollow Fiber Membranes For Biomedical And Bioprocessing Applications, Benjamin R. Madsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Hollow fiber membranes (HFMs) formed through phase inversion methods exhibit specific physicochemical characteristics and generally favorable surface and mechanical properties, supporting their use in diverse applications including ultrafiltration, dialysis, cell culture, bioreactors, and tissue engineering. Characterization of, and modifications to, such membranes are important steps in achieving desired characteristics for specific applications.
HFMs subject to gas, irradiation, and chemical sterilization techniques were characterized based on several analytical techniques. It was revealed that these common sterilization techniques can cause inadvertent changes to HFM properties. While these changes may cause detrimental effects to HFMs used in filtration, the methods of sterilization are …
