(230d) Hierarchical Porous Reduced Graphene Oxide/Polyaniline Composite By a Facile Method

Hydrogel of Na₂CO₃, CaCl₂ and graphene oxide was synthesized by the hydrothermal method using glucose as the reducing agent. The reducing process was accompanied by generation of CaCO₃ nanoparticles. Hierarchical porous reduced graphene oxide/Polyaniline Composite was obtained by dilute polymerization in the presence of the hydrogel. The structure and composition of the nanocomposite has been characterized by transmission electron microscopy (TEM), Atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), Raman spectra, Thermo Gravimetric Analysis (TGA) and fluorescence spectra. The composite was used as an electrode material for supercapacitors exhibited a synergistic effect of carbonaceous nanomaterials and conducting polymers.
