Advances in Polymer-based Nanostructured Membranes for Water Treatment

Water pollution has become the most severe dilemma in the entire world. In this review, we have discussed the advancement in preparation and properties, plus background and challenges regarding polymer-based nanocomposite membranes. Nanofiltration thin film composite membranes have been given tremendous attention over last two decades relative to conventional systems in desalination of sea water, waste water from industries and ultra pure water production etc. In recent years, significant research efforts have been devoted towards the development of high-performance membranes through surface modification of polymers and nanoparticles, nanotubes, etc. to achieve appreciable salt rejection, water flux and antifouling properties.
