Abstract: Hybrid composites have been prepared by solution processing method using various MWCNT concentrations in reduced graphene oxide/poly(3,4- ethylenedioxythiophene) polystyrene sulfonate (rGO-PEDOT:PSS) matrix. Structural and morphological characteristics of the prepared composite films have been characterized by X-ray diffraction, scanning electron microscopy, field emission scanning electron microscopy, Raman spectroscopy, UV–visible spectroscopy and Fourier transform infrared spectroscopy. The electrical transport measurement of composites conducted by four-point contacts shows increase in conductivity with MWCNT wt% in the composite system. The enhanced electrical conductivity as a result of improved dispersion of MWCNTs and rGO has been observed barely affecting the optical properties in the visible region. The observed improvement in electrical properties barely affecting its optical properties in the visible region can be attributed to synergistic effect of MWCNTs and rGO networks on the composite. This result suggests that such hybrid composite materials could be used as transparent conductor applications in optoelectronic devices.
