Current-voltage characteristics of electrochemically synthesized multi-layer graphene with polyaniline

In the present investigation, GNS have been prepared by an aqueous anodic exfoliation of pencil graphite in an acidic medium at different dc voltages (5 Ve12 V). The GNS prepared at optimum voltage were mixed with polyaniline (PANI) polymer and drop casted on an indium tin oxide (ITO)/Polyethylene terephthalate (PET) substrate to study the I-V characteristics and to measure the band gap of composites.
