PPy-CdS nanocomposite and multilayer thin film was deposited on Al substrate using electrodeposition technique. The presence of CdS particle in the composite film was proved using XRD and Micro-Raman spectroscopy. The roughness of the composite film was very low and it to be 4.96 nm. The fractal self-similarity of the composite films was estimated as 1.06. The resistance of PPy film along the polymer chain (sheet resistance) was 92.2 Ω and the resistance across the polymer chain (volume resistance) was 9.7 KΩ. However, the value of sheet resistance was 19.3 KΩ and the volume resistance was 43.6 KΩ for PPy-CdS nanocomposites film. Polymers acted as a corrosion protection layer for CdS nanoparticles. The rise and decay time constant of PPy-CdS nanocomposites film were obtained as 150s and 200s respectively and PPy-CdS multilayer films with bridge configuration were 203 s and 480 s respectively.
