Fabrication of BaTiO₃-Loaded Graphene Nanosheets-Based Polyarylene Ether Nitrile Nanocomposites with Enhanced Dielectric and Crystallization Properties

In this paper, barium [email protected] phthalocyanine ([email protected]) and graphene oxide (GO) hybrids ([email protected]) 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 [email protected] [email protected] and PEN composites ([email protected]/PENs) are obtained through the solution-casting method. [email protected] 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 [email protected] can be used as a nucleating agent to promote the crystallization of the nanocomposites. As a result, The [email protected]/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 [email protected] can be an effective additive for preparing high-performance PEN-based nanocomposites. View Full-Text
