Synthesis and characterization of reverse osmosis polymeric composite

Present study was conducted to synthesize and characterization of Polyurethane Polyvinyl Chloride reverse osmosis polymeric composite membrane. This was done by casting membranes from Polyurethane/Polyvinyl Chloride blend with and without Silicon Dioxide. Polymeric membrane of Polyurethane/Polyvinyl Chloride were synthesized with different concentration of Silicon Dioxide (filler) i.e. 5%, 7%, 10%, 12.5% and 15%. After synthesis characterization of the prepared membrane by different techniques including functional group study via Fourier Transform Infra-Red Spectroscopy, Scanning Electron Micrographic investigation, Differential Scanning Calorimetric analysis, Thermo Gravimetric Analysis, Water Swelling Index, Oxidative Stability and Ion Exchange Capacity were also done.
