Abstract: In this paper, GO/PANI/NPs (NPs = CdSe, CdSe/CdS, CdSe/ZnS) nanocomposites have been prepared using chemical method. The electrical properties of CdSe quantum dots, core shell nanoparticles (CdSe@CdS and CdSe@ZnS), graphene oxide/polyaniline nanocomposite (GO/PANI) and graphene oxide/polyaniline/nanoparticles (GO/PANI/NPs) nanocomposites have been measured using electrometer/high resistance meter (Keithley 6517A) at different wt% ratio. The above obtained nanoparticles (CdSe, CdSe@CdS and CdSe@ZnS) show the electrical current in nano ampere (nA) range while GO/PANI nanocomposites show the electrical current in miliampere (mA) range in the I-V measurement. The results of this study have been expected to reveal the effect of finite particle size on the conductivity of nanoparticles. The observed electrical conductivity of GO/PANI/NPs nanocomposites has been significantly reduced after the mixing of above obtained nanoparticles in different wt% ratio with GO/PANI nanocomposites. The knowledge of electrical conductivity and the effective mechanism for the conduction in nanocomposite is important for the fabrication of an electronic device such as solar cell.
