Synchrotron X-ray Characterization of Irradiated Ag/PVA Polymer Electrolyte — Mohamed Salah Soliman Asser and •Mohamed Salah Soliman Asser — Polymer Chemistry Department, National Center for Radiation Research and Technology, Egyptian Atomic Energy Authority, Cairo, Egypt.

Polymer electrolyte membrane thin films were developed and characterized for potential use in electroconductive applications. Polymer composites of polyvinyl alcohol (PVA), sulfuric acid, ethanol, and silver nitrate were prepared using both casting and dip-coating techniques. For the dip-coating method, glass slides were first cleaned by immersion in acetone, rinsed with isopropanol, and dried. The prepared polymer composite solutions were then dip-coated onto the glass substrates. The coated slides were irradiated at three doses: 62 J/cm2 (low), 251 J/cm2 (medium), and 502 J/cm2 (high) using the DXRL beamline. High-resolution X-ray diffraction (HR-XRD) analyses were performed at the Elettra Synchrotron Laboratory, Trieste, Italy, using the MCX beamline at a glancing angle of 1^∘. The X-rays had an energy of 12 keV (λ = 1.033 Å). Diffraction patterns were recorded in the 2θ range of 1*80^∘ with a step size of 0.01^∘ and an exposure time of 1 s per step for the Ag*PVA samples.
