  • ELECTROSPUN NANOFIBER COMPOSITES FOR WATER TREATMENT APPLICATIONS
    Publication number: 20200317903
    Abstract: Composites comprising polymeric nanofibers, metal oxide nanoparticles, and optional surface-segregating surfactants and precursor compositions are disclosed. Also disclosed are nonwoven mats formed from the composites and methods of making and using the composites. The composites enable the deployment of nanostructured materials for water treatment within a self-contained membrane with high water fluxes, as well as a number uses.

  • MESOPOROUS ALUMINA/HEMATITE COMPOSITE NANOFIBERS FOR HEAVY METAL REMOVAL
    Publication number: 20200047150
    Abstract: A method is disclosed of synthesizing ?-alumina/hematite (?-Al2O3/Fe2O3) composite nanofibers for removing heavy metals from a water source. The method includes preparing a polymer solution, the polymer solution comprising an iron precursor, acetic acid and a polymer; adding a select amount of an aluminum precursor to the polymer solution; and electrospinning the polymer solution and the select amount of the aluminum precursor to form the ?-Al2O3/Fe2O3 composite nanofibers.
