Description
Zinc oxide nanoparticles synthesized by hydrothermal technique are used as reinforcements to synthesize polyaniline nanocomposite via in-situ chemical oxidation method. The XRD analysis confirms the formation of polyaniline/zinc oxide nanocomposites. SEM images shows that nano reinforcement is covered with polymer matrix. Nanoparticles are found to be immersed in polyaniline matrix in the TEM images of nanocomposites. Significance of filler morphology in polyaniline nanocomposites is analysed by reinforcing zinc oxide nanoflowers, rods and spheres into polyaniline. Addition of metal oxide into polyaniline improves thermal stability. An increase of 227 % in UV absorption is observed for nanoflower composite compared to pure polyaniline in the absorption spectrum. Photoluminescence spectral analysis shows minimum peak intensity for polyaniline/zinc oxide nanoflower composite. Based on the optical property analysis, Dye-sensitized solar cells are fabricated by coating polyaniline and its nanocomposite with zinc oxide nanoflower. Power conversion efficiency of 5.23 % is obtained for the device based on pristine polyaniline and 7.03 % for nanoflower composite. 2026 Indian Chemical Society.
