Physical and electrochemical investigations on hybrid materials synthesized by polyaniline with various amounts of ZnO nanoparticle

Hybrid-materials were prepared via chemical polymerization in presence of aniline with various amounts of ZnO. The structural, functional, optical, morphological and electrical properties of nanocomposites were investigated by XRD, FT-IR, UV-Visible, TGA, SEM and electrical conductivity. XRD and SEM analysis shows the formation of nanocomposite and confirms the amorphous and crystalline nature of material. FT-IR spectrum reveals the functional groups present in the samples and the electroactive and optical properties were affected. Results showed that our nanocomposites exhibited a direct optical energy gap that decreased from 3.12 to 2.76 eV with the increment of the amounts of ZnO in nanocomposite.
