Abstract

We present the reduction of solution processed graphene oxide films by hydrogen iodide vapor. The films were studied by Raman spectroscopy and Fourier-transform infrared spectroscopy and its optoelectronic properties characterized. We obtained reduced graphene oxide films on polyethylene terephthalate flexible substrates with good electrical properties, $3.74\times {10}^{-6}\hspace{0.17em}\hspace{0.17em}\mathrm{\Omega }·\mathrm{m}$, and high optical transmittance of 70% in the visible range. The fabricated layers contain graphene sheets with sizes up to $\sim 10\mathrm{\mu m}$ long and $\sim 6\mathrm{\mu m}$ wide. The presented solution, with highly concentrated processed graphene oxide, could be used as printing ink for manufacturing transparent and conductive electrodes on plastic substrates without the requirement of elevated temperatures.
