High-k composites with sandwich structure by introducing a negative permittivity layer with Ni as conductive filler

SeO2Microwires Designed as Low‐Temperature Abrupt Microelectronic Switches, Negative Resistance, and Negative Dielectric Constant Sources

“…[ 26 ] The negative dielectric constant is a property of conductive materials such as metals, graphite and superconductors. [ 27 ] This behavior of the dielectric constant is expected because the microwires show degenerate (metal like) I–V characteristics. The negative dielectric constant is probably assigned to the increase in AC conductivity.…”

Polymer-based dielectrics with high permittivity and low dielectric loss for flexible electronics

“…Here, the high dielectric constant layer has two functions: (1) it provides a high dielectric constant for the whole dielectric layer of the film capacitor; (2) it forms an interface with adjacent layers to block the development of “tree-like” breakdown patterns. 183,191,192 Generally, multilayer coextrusion is a conventional and effective process method to fabricate a single structure with multiple layers. 33 As shown in Fig.…”

Sandwich‐structured PPy‐TiO 2 /PVDF composite films with outstanding dielectric properties and energy density

“…The dielectric constant of the composite with sandwich structure is 136 and the ultra-low loss is 0.028 (10 kHz) [18]. The dielectric loss of BFT/PVDF-Ni/PVDF sandwich polymer matrix composites prepared by Zhuo Wang et al is only 0.14 [19]. Jiyong Liang et al inserted a compact CLCNT sheet/PVDF dielectric layer between two PVDF insulating layers.…”
