Carbon nanotubes (CNT) and graphene are two significant carbon based nanomaterials which have extraordinary physicochemical properties, used in diverse fields of research. Recently, some actual studies were made to associate these carbon nanomaterials to produce CNT-graphene hybrid with synergic effects of graphene and CNTs. Addressed herein, EDOT-modified reduced graphene oxide (rGO), functionalized multiwalled carbon nanotube (f-MWCNT) and hybrid material (rGO-f-MWCNT) have been prepared. Then, PEDOT-modified composite films were synthesized via electrochemical polymerization to examine enhancing electrochemical properties of PEDOT and characterized by SEM, AFM analysis. As a conclusive finding, an improved stability, charge density, electrochromic switching kinetics and optical contrast of polymer composite films were observed on presence of nanocarbon materials in comparison to the control PEDOT film due to facile ion transport, high surface area
