Effect of Ag nanoparticles on AC electrical parameters of PVA–PAAm and PVA–PMMA-PAAm blends

This revision aims is to examine the electrical possessions of AC composite materials Polyvinyl alcohol-Polyacrylamide-Silver (PVA-PAAm-Ag) and Polyvinyl alcohol-Polyacrylamide-Polymethyl methacrylate-Silver (PVA-PAAm-PMMA-Ag) at different frequencies between 100 Hz – 6 MHz and the Ag additives. PVA-PAAm-Ag and PVA-PAAm-PMMA-Ag were prepared using the solution casting method. The film thickness was measured using an electrical micrometer to be 80 µm. The LC meter is used for the AC electrical properties. The results show that the dielectric constant (ɛ) and dielectric loss (δ) decrease with the increasing frequency, and δ increased with the increasing content of Ag. Electrical conductivity (σ) augmented with the rising frequency and Ag content in PVA-PAAM-Ag and PVA-PAAM-PMMA-Ag composite.
