Studies on copper coated polysulfone/modified poly isobutylene alt-maleic anhydride blend membrane and its antibiofouling property

► Nanofiltration is gaining more importance in the field of desalination. ► A new approach for desalination with an antimicrobial membrane. ► Copper coating onto membrane surface plays as biofouling protective layer. ► Copper coated membrane can maintain good salt rejection and appreciable flux. ► Copper coated membrane can resist possible microbial attack.
