Polymer Composite and Nanocomposite Dielectric Materials for Pulse Power Energy Storage
Peter Barber,Shiva Balasubramanian,Yogesh Kumar Anguchamy,Shushan Gong,Arief Wibowo,Hongsheng Gao,Harry J. Ploehn,Hans-Conrad zur Loye +7 more
TL;DR: In this article, a review summarizes the current state of polymer composites used as dielectric materials for energy storage, focusing on materials: polymers serving as the matrix, inorganic fillers used to increase the effective dielectrics constant, and various recent investigations of functionalization of metal oxide fillers to improve compatibility with polymers.

The mechanisms leading to the useful electrical properties of polymer nanodielectrics
TL;DR: In this article, the authors present the following hypothesis for the mechanisms leading to improved properties of polymer nanocomposites with metal oxide nanoparticle fillers: the inclusion of nanoparticles provides myriad scattering obstacles and trap sites in the charge carriers' paths, effectively reducing carrier mobility and thus carrier energy.

Polar plot representation for frequency-domain analysis of fluorescence lifetimes.
Glen I. Redford,Robert M. Clegg +1 more
TL;DR: Polar plots of frequency-domain data are commonly used for analysis of dielectric relaxation experiments (Cole–Cole plots), which have proved to be exceptionally useful in that field for decades.

Dielectric relaxation in solids
TL;DR: In this paper, a broad-brush view of dielectric relaxation in solids is presented, making use of the existence of a universality of Dielectric response regardless of a wide diversity of materials and structures with dipolar as well as charge-carrier polarization.

D. W. Davidson,R. H. Cole +1 more
TL;DR: In this article, complex dielectric constants have been measured at frequencies from below 20 c/s to 5 mc/s over the temperature range −40° to −75°C in glycerol, −45°-to −90° in propylene glycol, and −80°-140° in npropanol.

Relationship between the time-domain Kohlrausch-Williams-Watts and frequency-domain Havriliak-Negami relaxation functions
TL;DR: A connection among the parameters of both models is obtained, which is expected to be valid for those experimental data that can be described by either the KWW or the HN model, and has been tested by using dielectric-spectroscopy measurements, both in frequency and time domains.
