Abstract
A method for making a titania-polymer nanocomposite by simultaneously forming TiO2 nanoparticles in situ from a TiO2 precursor in the presence of urea and interfacially polymerizing polyamide precursors thereby producing a titania-polymer nanocomposite. A titania-polymer nanocomposite made by this method. A method for removing a dye or metal from water comprising contacting contaminated water with the titania-polymer nanocomposite.
Claims13
A titania-polyamide nanocomposite made by a method comprising:
- simultaneously forming TiO2 nanoparticles in situ from a TiO2 precursor in the presence of urea and interfacially polymerizing polyamide precursors thereby producing a titania-polyamide nanocomposite,
- wherein the simultaneous forming comprises:
- admixing 1,3-phenylene diamine, TiCl4 and urea to form an aqueous solution, and mixing the aqueous solution with a non-aqueous solution of trimesoyl chloride.
