Abstract
Graphene nanosheets (GNS) synthesized through commercially available pencil lead were used to prepare composites with polyaniline on ITO coated PET substrate. IV characteristics of the GNS-PANI composite device shows a decrease in band gap of PANI from 2.8Â eV to 6.9Â meV at 15Â 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 15Â wt% GNS-PANI, further confirming the formation of the composite at 15Â wt%. Instead of the in-situ polymerization process, the polymer and graphene were mixed externally in the desired concentrations and cast on the substrate directly, thereby offering a good control over the composition of the composite material.
