Fabrication of Ag/PVA nanocomposites and their potential applicability as dielectric layer in thin film capacitor

Over the past decade, polymer–metal nanocomposites have drawn a great deal of attention due to their extensive application in organic flexible devices. Here, we describe the synthesis and characterisation of silver–polyvinyl alcohol nanocomposite thin films and investigates the possibility of application of these composite films as dielectric layer in efficient capacitors. The material characterisation is done through UV–vis absorption, scanning electron microscopy and atomic force microscope. The dielectric property of the nanocomposite material is investigated with a LCR meter. The different fabricating parameters for generating homogeneous thin films are optimised in this investigation. The composite material thin films exhibit high capacitance density and low dielectric loss and hence they may be suitable ingredients for high capacitance capacitors.
