چکیده انگلیسی
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.
