Table 6 Pervaporation of 1-butanol from aqueous solution (5 wt.% 1-butanol) using TFC membranes with a PIM-1 separation layer on poly(vinylidene fluoride) (PVDF) or cellulose acetate (CA) porous supports. Fillers added to the PIM-1 separation layer are modified fumed silica nanoparticles (MNFS), modified carbon black nanoparticles (APTS-CB), small (lateral size in nm range) flakes of octadecyl-functionalised graphene oxide before (GO-ODA-S) and after (rGO-ODA-S) reduction and small flakes of octyl-functionalised reduced graphene oxide (rGO-OA-S)
