Nanocomposite films, based on polypyrrole (PPy) and polyethylene oxide (PEO), which can be doped with silver nitrate (AgNO₃) nanoparticles, were synthesized using pyrolysis spray technique at room temperature. The systematic study of optical and electrical properties of the prepared films was performed depending on dopant concentration (0, 3, 6, 9 and 12 wt. %). At about 400 nm, the UV-Vis spectrometer exhibits a noticeable absorption peak. Higher concentrations of AgNO₃ intensify the peak, especially in the sample containing 12% AgNO₃. Hall measurements were used to establish the type, concentration of charge carriers, and Hall mobility (μ_H). The results showed that the nanocomposite films had a negative Hall coefficient (n-type) prior to the addition of AgNO₃ nanoparticles. The polymer mix films exhibit (p-type) conductivity with a positive Hall coefficient at all AgNO₃ nanoparticle concentrations. In D.C. studies, electrical resistance decreases as temperature rises, but the nanocomposite film's D.C. conductivity rises as AgNO₃ nanoparticle concentrations rise. Across all produced samples, alternating electrical conductivity (σ_a.c) increases as frequency increases. At low frequencies, the alternating electrical conductivity (σ_a.c) doesn't change.
