POLYCARBONATE-SILICA NANOCOMPOSITE MEMBRANES FOR CARBON DIOXIDE SEPARATION

Polymeric membranes suffer permeability-selectivity trade-off challenge due to the structure-property limitation of the material. To overcome this, polymer-inorganic composites membranes are proposed for carbon dioxide (CO2) separation. In this study, polycarbonate (PC) as core polymer and silica as...
