Mechanical properties and interfacial adhesion of composite membranes probed by in-situ nano-indentation/scratch technique
Abstract(#br)The mechanical strength and interfacial behavior have been of great significance for composite membranes. In this work, an in-situ nano-indentation/scratch technique was employed to probe mechanical properties and interfacial adhesion of ceramic-supported polydimethylsiloxane (PDMS) composite membranes. The nanostructures of active, transition and support layers were systematically correlated with measured mechanical and adhesive properties, as well as interfacial morphologies and separation performance.
