There has been an increasing demand for more efficient and cheaper ways to filter water as pollution and climate change have led to a build-up of contaminants in current water sources.  Membrane filtration has been employed to remove these pollutants, with nanofiltration being one of the more popular tracks as it employs membrane pores of sizes on the nanometer scale that selectively reject molecules of varying weights.  We aim to create nanofiltration membranes using surfactants, a substance with both polar and nonpolar ends that self-assemble in a solvent, adding a cross-linking reagent to spontaneously cross-link the material under exposure to ultraviolet radiation.
