Polymeric dielectrics have applications in energy storage devices but their potential utility can be compromised by the presence of loss processes. The present project was concerned with identifying the molecular mechanisms underlying and responsible for losses. The program and results involved a two- fold approach to understanding loss processes occurring below the glass transition. This is an important regime since the polymers have structural integrity in the glassy state. One of the two approaches was experimental and the other involved molecular modelling. The ester group was taken a chemical structural model for loss processes originating as the result of flexible side group motion in an otherwise glassy polymer energy storage, Dielectric, Dielectric loss, Dielectric constant, Dielectric loss mechanism, Dielectric relaxation processes, Subglass relaxation processes, Polymeric dielectric, Molecular modelling.
