Does anyone here have any materials on the preparation of solvent-resistant nanofiltration membranes? Thank you
Solvent-resistant – resistant to what kind of dissolution? Various solvents are different from each other

Nanofiltration membranes generally cannot be backwashed, as many of them are three-layer composite membranes; it is the thinnest uppermost layer that performs the separation function, and backwashing will damage the membrane
Solvent-resistant nanofiltration membranes were originally produced abroad, but many of those productions were discontinued later on
