Polyarylene Ether Nitrile-Based High-k Composites for Dielectric Applications

Abstract

Flexible polymer-based composites exhibiting high dielectric constant as well as low dielectric loss have been intensively investigated for their potential utilization in electronics and electricity industry and energy storage. Resulting from the polar -CN on the side chain, polyarylene ether nitrile (PEN) shows relatively high dielectric constant which has been extensively investigated as one of the hot spots as dielectric materials. However, the dielectric constant of PEN is still much lower than the ceramic dielectrics such as BaTiO 3 , TiO 2 , and Al 2 O 3 . In this review, recent and in-progress advancements in the designing and preparing strategies to obtain high-k PEN-based nanocomposites are summarized. According to the types of the added fillers, the effects of organic fillers, dielectric ceramic fillers, and conductive fillers on electric properties of PEN-based composites are investigated. In addition, other factors including the structures and sizes of the additive, the compatibility between the additive agent and the PEN, and the interface which affects the dielectric properties of the obtained composite materials are investigated. Finally, challenges facing in the design of more effective strategies for the high-k PEN-based dielectric materials are discussed.

Regression Analysis of the Dielectric and Morphological Properties for Porous Nanohydroxyapatite/Starch Composites: A Correlative Study

“…It induces the formation of the clusters that are due to the significant agglomeration effect. It is not conducive to the formation of porous structures [ 14 , 29 , 30 , 31 ]. It causes a decrement in average pore size (82.9 μm) and porosity (64.5%) of the H7S3 composite, as shown in Figure 2 .…”

Polyarylene Ether Nitrile and Barium Titanate Nanocomposite Plasticized by Carboxylated Zinc Phthalocyanine Buffer

“…The ZnPc, which was wrapped on the surface of BT, showed excellent compatibility with the PEN matrix which contributed to the enhanced properties of the system. Polyarylene ether nitrile (PEN) whose structure is shown in Scheme 1 was firstly synthesized through nucleophilic aromatic substitution polymerization according to the literature mentioned technique [21,22]. BT@ZnPc was then prepared through the esterification between the carboxyl from the ZnPc-COOH and the hydroxyl on the peripheral of hydrogen peroxide treated BT (BT-OH).…”

“…Hydrogen peroxide (H 2 O 2 ), tetrahydrofuran (THF), and N -methyl-2-pyrrolidone (NMP) were supplied by Tianjin Bodi Chemicals, Tianjin, China. PEN (Scheme 1) was polymerized through nucleophilic aromatic substitution polymerization according to the procedure reported in the literature [21,22]. ZnPc was synthesized by a zinc chloride catalyzed self-cyclization reaction of diphenyl bisphthalonitrile in an NMP solution [23,24].…”

Achieving Secondary Dispersion of Modified Nanoparticles by Hot-Stretching to Enhance Dielectric and Mechanical Properties of Polyarylene Ether Nitrile Composites

“…In comparison, polymeric materials have exhibited the advantages of being lightweight and flexible, but their low dielectric constant also limits their application to a great extent [5,6,7]. Therefore, combining the two-component materials is an effective way to overcome these limitations [8,9,10].…”
