“…A shown by formula (6), high breakdown electric field ( E b ), high P max , and low P r are preferred to achieve high energy storage density. To improve the dielectric breakdown strength of ferroelectric materials, the common strategies are: (1) reduce the sample thickness and electrode area [ 55 , 56 ]; (2) increase the density of the material [ 57 ]; (3) increase the width of the material forbidden band [ 58 ]; (4) increase the insulation of the material [ 59 , 60 ]; (5) implant dead layer [ 61 , 62 ]; (6) anneal in oxygen [ 63 , 64 ], and so on. Although these methods are very effective for systems that do not contain volatile elements such as BaTiO 3 , but for some systems rich in volatile elements, such as Bi, Pb, Na, K for example BiFeO 3 , PbZrO 3 , Na 0.5 K 0.5 NbO 3 , Na 0.5 Bi 0.5 TiO 3 , etc.…”

Dielectric capacitors are widely used in pulse power systems, electric vehicles, aerospace, and defense technology as they are crucial for electronic components. Compact, lightweight, and diversified designs of electronic components are prerequisites for dielectric capacitors. Additionally, wide temperature stability and high energy storage density are equally important for dielectric materials. Ferroelectric materials, as special (spontaneously polarized) dielectric materials, show great potential in the field of pulse power capacitors having high dielectric breakdown strength, high polarization, low-temperature dependence and high energy storage density. The first part of this review briefly introduces dielectric materials and their energy storage performance. The second part elaborates performance characteristics of various ferroelectric materials in energy storage and refrigeration based on electrocaloric effect and briefly shed light on advantages and disadvantages of various common ferroelectric materials. Especially, we summarize the polarization effects of underlying substrates (such as GaN and Si) on the performance characteristics of ferroelectric materials. Finally, the review will be concluded with an outlook, discussing current challenges in the field of dielectric materials and prospective opportunities to assess their future progress.

“…The conditions for humidity/temperature procedure, have been chosen on the basis of values found in the literature [6], [7] (treatment for 21 h at 70 C at 90% RH). The conditions for flux contamination procedure and outgassing have been chosen as reported in report ESA STM-267 [9].…”

“…Previous work [6], [7] report test results on the humidity/temperature conditioning of epoxy PCBs for 48 h; it was demonstrated that humidity absorption by this material caused a variation of surface resistivity and that the water absorption changed with an increase in temperature. The effect of water (high humidity) on these various laminates is extremely important for high-reliability circuits.…”

New dielectric materials have been introduced for printed circuit board applications, such as Thermount and polyimide with the aim to match the requirements for high speed and high density of electronic devices that are planned for new spacecraft electronic boards. Before these newer substrate can fully replace the well-known space-approved material epoxy FR-4, it is necessary to investigate more deeply their electrical and mechanical properties. The scope of this study is to report quantitative characterization of the surface resistivity for the different material samples under various testing conditions that include relative humidity, temperature, solder flux contamination, and corona discharge. The surface resistivity results are reported for sets of samples measured under a combination of testing conditions.
