Conducting polypyrrole (PPy) nanoparticles were synthesized via four different radical polymerization systems changing the time and other parameters. The characterization of PPy nanoparticles was done by Fourier transform infrared spectrometer. Graphene was synthesized from intercalated graphite by exfoliation at 1000 $${^{\circ}}$$ ∘ C for 30 s in tube furnace, and particle size was assessed...
