“…Wei et al [70] investigated that the polyaniline (PANI) was doped with sulfuric acid as a filler to prepare PEN/PANI composite films for improving the dielectric permittivity of PEN by using solution casting method. It is clearly seen that there was just a T g of the composites on DSC curves, and no phase separation was observed on the SEM images.…”

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.

“…The dielectric materials including the polypropylene (PP) [13], biaxially oriented polypropylene (BOPP) [14], polyethylene terephthalate (PET) [15], poly(vinylidene fluoride) (PVDF) [16,17], and polyarylene ether nitrile (PEN) [18][19][20][21][22], among others, have recently attracted considerable attention from the material research community. In comparing with the inorganic dielectric materials, the dielectric materials especially the polymeric dielectric materials exhibit the advantages of low intrinsic density, excellent performance, easy processing, long serving life, and even recyclability [11].…”

“…In comparing with the inorganic dielectric materials, the dielectric materials especially the polymeric dielectric materials exhibit the advantages of low intrinsic density, excellent performance, easy processing, long serving life, and even recyclability [11]. However, pure polymer material suffers from the defect of low dielectric constant [21,22]. As a result, preparing polymer-based composite which combines the advantages of polymer material and inorganic additive has been intensively investigated in recent years [23][24][25].…”

“…However, the addition of the inorganic additive also results in the increment of the dielectric loss of the system [23,24]. Another method to improve the dielectric constant of a polymer is to increase the polar groups in the polymer, as the dielectric constant indicates how easily a material can become polarized by imposition of an electric field on an insulator [21]. For example, PEN is widely used as dielectric materials for its high dielectric constant attributing to the polar cyano groups as the side-chains on the backbone [18][19][20][21].…”

The relationship between the structure and the dielectric properties of the azo polymers was studied. Four azo polymers were synthesized through the azo-coupling reaction between the same precursor (PAZ) and diazonium salts of 4-aminobenzoic acid ethyl ester, 4-aminobenzonitrile, 4-nitroaniline, and 2-amino-5-nitrothiazole, respectively. The precursor and azo polymers were characterized by 1 H NMR, FT-IR, UV-vis, GPC, and DSC. The dielectric constant and dielectric loss of the samples were measured in the frequency range of 100 Hz-200 kHz. Due to the existence of the azo chromophores, the dielectric constant of the azo polymers increases compared with that of the precursor. In addition, the dielectric constant of the azo polymers increases with the increase of the polarity of the azo chromophores. A random copolymer (PAZ-NT-PAZ) composed of the azo polymer PAZ-NT and the precursor PAZ was also prepared to investigate the content of the azo chromophores on the dielectric properties of the azo polymers. It showed that the dielectric constant increases with the increase of the azo chromophores. The results show that the dielectric constant of this kind of azo polymers can be controlled by changing the structures and contents of azo chromophores during the preparation process.

The hydroquinone (HQ) and bisphenol A (BPA) type poly(arylene ether nitrile) (PEN) (HQ/BPA-PEN) were synthesized through nucleophilic aromatic substitution polymerization from HQ, BPA, and 2,6-dichlorobenzonitrile (DCBN). The prepared copolymers were characterized by intrinsic viscosity, Fourier transform infrared (FTIR), and dynamic rheological analysis. The properties of resultant copolymers were studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and mechanical testing. The results showed that the PEN copolymers exhibited crystallization performance with excellent thermal and mechanical properties. HQ/BPA-PEN10 was made into films by solution-casting process and then were treated at different temperatures (200, 260, 280, 300, 310, and 320 8C) for different times (1, 2, 3, 4, and 5 h) to investigate the crystallinity. Results showed that when isothermal treatment temperature is 310 8C and isothermal treating time is 4 h, HQ/BPA-PEN10 showed best properties. At this condition, the melting enthalpy, crystallinity, tensile strength, and elongation at break of the sample is 17.7 J/g, 14.11%, 132.9 MPa, and 6.1%, respectively.
