文摘
A PSf self-standing nanofilm doped with SPSf was developed by solvent evaporation. The structure and surface property of the nanofilm were regulated by SPSf doping. The nanofilms with the thickness from 46 to 219 nm were applied in FO process. A high water flux of 46.4 LMH at the osmotic pressure of 6.2 MPa was observed.
