摘要: We have covalently functionalized reduced graphene oxide with camphor sulphonic acid doped polyaniline using phenylene diamine as a linker and the hybrid was characterized by Fourier transform infrared spectroscopy, X-ray diffraction analysis, photoelectron UV-Visible spectroscopy scanning electron microscopy. Nonlinear optical properties of hybrid, graphite pristine were investigated open aperture Z-scan technique at 532 nm. At same mass concentration (0.2 g/l), exhibited improved limiting compared to GO due synergetic combination nonlinear mechanisms oxide.
