MoS2 membranes exhibit pH-dependent water permeability switching with memory.

Researchers have discovered that MoS2 membranes exhibit pH-dependent water permeability switching and memory, which could be useful for nanofiltration applications. The membranes showed reversible and repeatable switching between high and low water permeability states in response to changes in pH, and the switching behavior was found to be stable over time. The study provides insights into the fundamental properties of MoS2 membranes and their potential for use in water filtration technologies.
