Dielectric spectroscopy of polymer-based nanocomposite dielectrics with tailored interfaces and structured spatial distribution of fillers

Emerging technologies in the areas of electronics and energy storage require the design of next-generation dielectric-component materials with well-defined structure and properties with higher performance under voltage and temperature. Polymers filled with inorganic nanoparticles are potential 94candidates for breakthrough advances, since they enable the integration of constituents with desirable properties, particularly when hierarchically structuring the filler phase. However, implementation of highly innovative material elements necessitates the fundamental understanding of each element’s properties and interactions at the nanoscale and, further, how those are manifested in the macroscopic performance of the nanocomposftes. Dielectric spectroscopy, coupled with performance measurements, is crucial in quantifying such properties and unveiling the molecular-level interdependences and their correlations with device performances.
