Studying Local Molecular Mobility in the Polymer Matrix of a Fuel Element via FTIR Spectroscopy

Abstract

© 2019, Allerton Press, Inc. Abstract: The local molecular dynamics in a polymer matrix based on polyvinylbutyral for solid polyelectrolyte is studied by means of FTIR spectroscopy. The effect low molecular weight polyethylene glycols with average masses of 200, 400, and 600 g/mol have on the effective size of the free volume elements and the ionic conductivity in the polymer matrix is considered in the context of the free volume model.
