| Abstract: | The track-etched polymeric membranes have higher permeability for hydrogen as well as carbon dioxide. In present work, we have deposited thin film of Ti having thickness 100-150 nm on polymer membrane surface using vacuum evaporation method under 10−6 Torr for filling the tracks by the Ti metal. The gas permeability of Ti-deposited membrane is modified because Ti has close affinity for hydrogen. The samples are characterized by UV-vis spectroscopy and optical microscopy. The Ti-coated, track-etched membranes are applicable for relatively higher permeation for hydrogen as well as higher selectivity and also these are technologically important for purification of hydrogen. |
