Characterization and electrical enhancement of PVP/PVA matrix doped by gold nanoparticles prepared by laser ablation

In this study, Polyvinyl Pyrrolidone (PVP)/Polyvinyl Alcohol (PVA) blend embedded by gold nanoparticles (AuNPs) was synthesized via traditional casting method to study the enhanced electrical conductivity of the blend. AuNPs were synthesized by Laser Ablation in Liquids Technique (PLAL). The physical characterization of the prepared PVP/PVA/AuNPs films have been performed by various techniques. The electrical conductivity of the prepared samples was evaluated. The structural characterization shows significant sharp diffraction peak at 2 theta = 38 degrees attributed to the plane (111) related to the presence of AuNPs. UV-Vis absorption spectra reveals the distinctive peak of AuNPs at 536 nm. SEM diffractograms approve the embedding of AuNPs in the surface of PVP/PVA. The electrical conductivity data approved enhancement the performance of the pure blend PVP/PVA after embedded with AuNPs prepared by laser ablation. Ac conductivity have been increased by increasing the ratio of AuNPs within PVP/PVA blend. Thus, these observations reflect the use of PVP/PVA/AuNPs samples in electrical applications.
