Description
Summary:PVA/PANI/Ag composite materials made of silver (Ag), polyaniline (PANI), and polyvinyl alcohol (PVA) are prepared for applied in electrical devices. The structure of PVA/PANI/Ag composites was analyzed using XRD, which indicating the samples were successfully synthesized. The crystallite size of AgNPs changed from 12.1 nm to 16 nm by increasing the Ag content from 3 to 6% in the PVA/PANI blend. Moreover, in temperature range 293–353 K, the impacts of PANI as well as AgNPs on the conductivities, permittivity, as well as energy density of PVA were investigated. The conductivity of the films was enhanced with higher frequency due to charge carrier mobility. Furthermore, the density is increased from 1.96 × 10 −6 J m −3 at 20 °C for PVA to 2.7 × 10 −6 for PVA/PANI/Ag. These results show the prepared PVA/PANI/AgNPs can applied in in a wide range of electronic technologies like batteries, electronic circuits, as well as super capacitors.
