Polysulfonylamide (PSA)
Chemical properties: PSA is a high-performance polymer that combines sulfone (- SO ₂ -) and amide (- CONH -) groups, with high temperature resistance, chemical corrosion resistance, and mechanical strength.
Polysulfonylamide (PSA) Description
Polysulfone amide is a very good material for making RO membrane. Comparing with other polyamides, its outstanding feature is resistance to free chlorine and oxidation, but the flux of corresponding membrane is low. In this work, the casting solution formula and membrane making condition have been modified to suit the requirement for industrial production, and also much efford have been done on improving the flux of the membrane by chemical modification of PSA.
