Graphene nanosheets (GNS) synthesized through commercially available pencil lead were used to pre-pare composites with polyaniline on ITO coated PET substrate. IeV characteristics of the GNS-PANI
composite device shows a decrease in band gap of PANI from 2.8 eV to 6.9 meV at 15 wt% loading of
GNS in PANI. SEM and Raman spectroscopy show good dispersion of GNS and interfacial interaction with
the GNS-PANI composite by a significant shift in the G peak at 15 wt% GNS-PANI, further confirming the
formation of the composite at 15 wt%. Instead of the in-situ polymerization process, the polymer and
graphene were mixed externally in the desired concentrations and cast on the substrate di...
