Abstract
Fresh leaves of Chenopodium murale (C. murale) have been used for the biosynthesis of gold nanoparticles (AuNP’s). AuNP’s have incorporated into polyethylene oxide /polyvinyl pyrrolidone (PEO/PVP) polymer blend by using the casting process. Transmission electron microscopy (TEM) reveals that AuNP’s are poly dispersed with size ranging 5–23.1 nm. Dc-conductivity shows an increase of conductivity (σ) with increasing temperature and the filler contents. Moreover, the AC conductivity (σac) and dielectric loss tangent (tan δ) have been investigated. The dielectric constant (e') and dielectric loss (e") are calculated from room temperature and up to 363 K. The inverse relation between permittivity (e′) and frequency was correlated to dipoles direction of the electric field while higher dielectric loss (e″) are attributed to the mobile charges in the blend matrices. Correlated barrier hopping model (CBH) proposed as a suitable route that elucidates the behavior of pure PEO/PVP polymer blend doped with Au-nanoparticles.
