Synthesis and characterization of polymer/V2O5 composites based on poly(2‐aminodiphenylamine)

Abstract

Hybrid materials consisting of aniline (ANI) and/or 2‐aminodiphenylamine (PD) in the presence of V2O5 nanoparticles were synthesized by in‐situ chemical oxidative polymerization in one‐step. Physicochemical and electrochemical characterization confirmed that in the structure of the composites, intercalation between the polymer chains and the V2O5 slabs occurs. Optical properties study shows that the optical band gap of poly(ANI‐co‐PD)/V2O5 is lower than poly‐PD/V2O5. Thermal stability of the composites by thermogravimetric analysis was evaluated. Composites showed electrochemical activity with improved electron‐transfer of the redox species in the polymer observed by cyclic voltammetry. These results highlight the great influence of the V2O5 sheets and the polymer composition on the hybrid materials formation and properties.
