Synthesis and structure of Zinc oxide doped Polyindole Nanocomposites

We present the synthesis and characterization of nano Zinc Oxide (ZnO), nano Polyindole (PIN), and nano PIN/ZnO composite in this work. Polyindole was produced by oxidative chemical polymerization using ferric chloride. Scanning electron microscopy (SEM) was used to analyze the structure and form of the PIN, PIN/ZnO nanocomposite and ZnO nanoparticle. The elemental analysis and chemical characterization were shown using the EDAX technology. The X-Ray Diffraction (XRD) technique was used to measure the crystallites' sizes and the degree of crystallinity. It is clear that the dopant improves conductivity since the UV-vis spectrum shows that the band gap of the doped PIN decreases.
