  Polymer Electrolyte Films Doped with Nanofillers ZnO: Electrochemical and Optical Investigations

  By Sonu Kumar, Sushma Kumari, Shashi Shankar Jha, Madhuri Singh, Rakesh Kumar Raushan, Smita Bharati, Mansi Ranjan

  Abstract: The electrochemical and optical characteristics of polymer composite electrolyte films doped with zinc oxide (ZnO) nanofillers are thoroughly examined in this work. Because of its superior film-forming capacity, flexibility, and ionic transport properties, poly(vinyl alcohol) (PVA) mixed with potassium iodide (KI) is used as the host polymer electrolyte. To investigate their effects on ionic conductivity, dielectric behavior, and optical transmission, ZnO nanoparticles are synthesized and added to the PVA–KI matrix …
