Composite Semipermeable Membrane, Composite Semipermeable Membrane Module, And Fluid Separation Device
Abstract: The present invention provides a composite semipermeable membrane that has excellent water permeability performance while having exceptional abrasion resistance. This composite semipermeable membrane comprises a support membrane, a separation function layer that contains a cross-linking polyamide, and a coating layer that is positioned on the separation function layer, the developed interfacial area ratio Sdr of the coating-layer-side surface being 60-200%, and the coefficient of static friction µs between the coating-layer-side surface and a wrapping film having a #2000 grain size being 0.40-1.30.
