Synthesis and Characterization of PPy:PEO Blend Dopant with AgNO3 Nanoparticles: Optical and Electrical Investigations
Main Article Content
Abstract
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 (μH). 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 (σa.c) increases as frequency increases. At low frequencies, the alternating electrical conductivity (σa.c) doesn't change.
