Abstract
A method is disclosed of forming core-shell iron oxide-polymer nanofiber composites. The method includes synthesizing composite nanofibers of polyacrylonitrile (PAN) with embedded hematite (α-Fe2O3) nanoparticles via a single-pot electrospinning synthesis; and generating a core-shell nanofiber composite through a subsequent hydrothermal growth of α-Fe2O3 nanostructures on the composite nanofibers of polyacrylonitrile (PAN) with the embedded hematite (α-Fe2O3) nanoparticles.
