“…According to previous reports [20], when the amount of ZnPc@BT is added as high as 30%, the dielectric constant of the composites is still about 6.0. This reveals that a significant increase in dielectric constant is achieved with low additions of graphene, which is due to the fact that heterojunction between the conductor and the ferroelectric increases the dielectric constant of the composites [29]. Meanwhile, the mismatch in conductivity between the two phases of GO and ZnPc results in more and more free carriers accumulating at the interface and producing strong interfacial polarization, which further leads to an increase in dielectric constant.…”

In this paper, barium titanate@zinc phthalocyanine (BT@ZnPc) and graphene oxide (GO) hybrids (BT@ZnPc-GO) connected by calcium ions are prepared by electrostatic adsorption, and then introduced into polyarylene ether nitrile (PEN) to obtain composites with enhanced dielectric and crystallization properties. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) results confirm the successful fabrication of the BT@ZnPc-GO. BT@ZnPc-GO and PEN composites (BT@ZnPc-GO/PENs) are obtained through the solution-casting method. BT@ZnPc-GO demonstrates well compatibility with PEN due to its unique structure and the organic layer of ZnPc at the periphery of BT. On the other hand, BT and GO contribute a high dielectric constant of the composites obtained. In addition, the BT@ZnPc-GO can be used as a nucleating agent to promote the crystallization of the nanocomposites. As a result, The BT@ZnPc-GO/PEN exhibits a dielectric constant of 6.4 at 1 kHz and crystallinity of 21.03% after being isothermally treated at 280 °C for 2 h at the GO content of 0.75 wt %. All these results indicate that the hybrid nanofiller BT@ZnPc-GO can be an effective additive for preparing high-performance PEN-based nanocomposites.

Poly(arylene ether nitrile) (PEN) is a class of high‐performance engineering plastics of poly(arylene ether) with cyano groups as side groups, which can get improved thermal, mechanical, and electrical properties through simple molecular structure design. In this work, a series of PEN (BPA/PP based PEN) copolymers were synthesized with varying amounts of phenolphthalein and bisphenol A. The influence of the copolymer molecular structure variations on the thermal, mechanical, and dielectric properties of PEN copolymer films was investigated. The results demonstrated that the BPA/PP based PEN copolymer films have great mechanical properties and low dielectric constant, as well as enhanced thermal properties. The highest 5% weight loss temperature of 494.9°C was obtained by PEN‐B7P3, while the highest glass transition temperature of 238.6°C was obtained by PEN‐B3P7. Porous BPA/PP based PEN films prepared by non‐solvent induced phase separation (NIPS) exhibited satisfactory mechanical properties and the highest tensile strength of 9.4 MPa was achieved. Moreover, the introduction of the phenolphthalein structure into the PEN molecular chain can improve the heat resistance of the PEN copolymers without deteriorating the dielectric properties, which gives the copolymers great potential as candidates for applications in flexible electronics and wireless communication.

In this work, Phthalonitrile containing benzoxazine (BA-ph) and Bisphenol A based cyanate ester (CE) were chosen as the matrix resin. Various amount of nano-SiO 2 was incorporated into BA-ph/CE and their glass fiber-reinforced composite laminates were fabricated. Curing reaction and processability of BA-ph/CE/SiO 2 blends were studied by differential scanning calorimetry and dynamic rheological analysis. Results showed that BA-ph and CE exhibited good processability and curing reaction of BA-ph/CE was not obviously affected by SiO 2. Scanning electron microscope images of the composites showed that SiO 2 particles were well dispersed in BA-ph/CE matrix. Moreover, SiO 2 could act as physical crosslinking points and diluent in matrix as well as between the glass fibers to improve the mechanical properties of composite laminates. As the results of dynamic mechanical analysis and thermogravimetry analysis, composite laminates possessed satisfactory T g and good thermal stability. With incorporation SiO 2 particles into matrix resin, dielectric constant and dielectric loss of BA-ph/CE/SiO 2 /GF composites were increased and showed frequency dependence.

Due to the inherent brittleness of thermosetting resins, pure thermosetting resins were hardly used as structural, substrate, or functional materials. In order to improve the brittleness of thermosetting resins, continuous fiber, nanoparticles were widely applied to reinforce the thermosetting resins to fabricate composites with enhanced properties. 1-4 Compared with that of traditional inorganic metal materials, fiber
