| dc.description.abstract | In this study, synthesis and characterization of graphene oxide-polyaniline-Ag nanocomposites (GO-PANI-Ag) as
a photothermal agent are demonstrated. In situ polymerization process was used to prepare the ternary nanocomposite
of graphene oxide, aniline, and Ag nanoparticles. The chemical and structural characteristics of the
nanocomposites were investigated by UV–Vis, FTIR, Raman, XRD, SEM, and TEM and photothermal properties
were examined in the NIR region. 1 mL of aqueous dispersions of the nanocomposites at various concentrations
were irradiated with the 808 nm NIR laser at 1.5, 2.0, and 2.5 W cm����� 2 laser power densities. The temperature of
GO-PANI4-Ag0.25 nanocomposite increased to 66.6, 80.1 and 90.6 ◦C at 1.5, 2.0, and 2.5 W cm����� 2 of power
density at 0.1 mg mL����� 1 for 5 min, respectively. The results showed that the GO-PANI-Ag nanocomposite has
excellent photothermal performance and high stability. The synthesized nanocomposite could be used as an
antibacterial agent or in cancer therapy. | tr |
