Preparation, Characterization and Properties of Newly Synthesized SnO2-Polycarbazole Nanocomposite via Room Temperature Solution Phase Synthesis Process

The introduction of inorganic metal oxide nanoparticles in a polymer matrix is found to significantly modulate its optical, electrical and electrochemical properties. Here, we report the one-pot synthesis of SnO2-polycarbazole (PCz) nano composite via solution phase technique (in situ chemical oxidative polymerization route) for the first time. The morphological and compositional analyses of these organic-inorganic hybrid nano composites were done by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), the Fourier transform infrared (FTIR) spectroscopy and ultraviolet-visible (UV-visible) spectroscopy. The successful loading of SnO2 nanoparticles by PCz was apparent from FESEM micrographs. UV-Visible spectroscopy revealed that optical property of the pristine PCz was significantly revamped after incorporation of SnO2 nanoparticles. The Synergetic interactions between polycarbazole and tin oxide nanoparticles were apparent from the FTIR and XRD spectra. Thermal stability of the material estimated by Thermo gravimetric (TGA) analysis; which shows thermal strength is significantly increased after incorporation of SnO2 nanoparticles in the PCz matrix. The I-V curve shows good ohmic contact of the material with tin electrode and electrical conductivity of the material is significantly altered with varying the loading percentage of SnO2 nano particles in PCz matrix.
