Synthesis and characterization of hybrid membranes using chitosan and 2-(3,4-epoxycyclohexyl) ethyltrimethoxysilane for pervaporation dehydration of isopropanol

- Total flux and flux of water are found to be overlapping for hybrid membranes.
- PSI data suggest that membrane with 40 mass% of ETMS showed excellent performance.
- Membranes have lower Epw values compared to EpIPA, exhibiting higher separation.
- Membranes exhibit negative ΔHs values, indicating the Langmuir's mode of sorption.
