Membrane forming ability of Polyvinyledenefluoride (PVDF) makes it of wider significance in membrane technology. However, hydrophobic nature of PVDF limits its application leading to the process of fouling. Different approaches are being employed to overcome this aforementioned issue. In the present study, novel PVDF/Nanodiamonds (NDs) nanocomposite membranes were formulated using solution casting technique using Dimethylformamide (DMF) as solvent. The morphology of the nanocomposite membranes were obtained by scanning electron microscope. The effects of addition of different weight percent of NDs (1-5 wt%) on shrinkage ratio, pure water flux, percentage of water content and porosity of the nanocomposite membranes were studied and results are discussed. It was established that with the increase in content into the nanocomposite membrane, the shrinkage ratio decreased while the pure water flux, water content and porosity of the membrane increased. Further, the applications of the PVDF/NDs nanocomposite membranes in separation of heavy metal ions from aqueous streams were also tested and the results are discussed.
