Synthesis, characterization, and ionic conductivity of nanocomposites: Polyelectrolyte systems

摘要

The synthesis, diffraction patterns, thermal stability, and ionic conductivity properties of methacrylate-type polymers are analyzed here to assess their feasibility as polymer electrolytes. From the parent polymer, poly (N,N-dimethylaminoethylmethacrylate), herein labeled PDMAEMA, a protonated derivative was used to prepare polymer/Montmorillonite nanocomposites with various clay contents (1, 3, and 5 wt %). AC spectroscopy provided the ionic conductivity data for the polymers and clay-polymer nanocomposites. Evidences of nanocomposite formation are shown using transmission electron microscopy and wide-angle X-ray diffraction.
