Development of robust and high-performance polysilsesquioxane reverse osmosis membranes modified by SiO2 nanoparticles for water desalination

Nanomaterials-modified reverse osmosis membranes: a comprehensive review

“…119 For instance, the incorporation of SiO 2 NPs into RO membranes led to enhanced thermal stability, as indicated by a minimal decrease in salt rejection of less than 2.5% aer heat treatment at 95 °C for 180 minutes. 120 Furthermore, the membranes demonstrated excellent resistance to chlorine exposure, with a salt rejection decrease of less than 2% even aer being exposed to 10 000 ppm h of NaOCl. 120 Further, TFN membranes were fabricated by IP process of MPD and TMC organic solution on silicon nitride/polyethersulfone (PES) composite substrate, as shown in Fig.…”
