One-pot Synthesis of Graphene Oxide-MnO2-Polyaniline Nanocomposites and Their Photothermal Properties

Abstract

Graphene oxide-MnO2-Polyaniline ternary nanocomposites were synthesized by a facile one-pot approach and characterized with UV-Visible spectroscopy, XRD and SEM. Photothermal properties of the nanocomposite dispersions were tested with an 808 nm wavelength near-infrared laser. Efficiency of the nanocomposites were calculated with time constant method and maximum efficiency was found to be 73.9 %. Additionally, cyclic heating cooling experiments proved the superb dispersion stability and photothermal performance of the nanocomposite.
