“…1241 cm −1 is the characteristic peak caused by the antisymmetric stretching vibration of the aromatic ether C−O−C. 36,37 The above peak positions reflect the PESU structural characteristics. With the increase of the content of the inorganic filler phase, the peak position of PESU is still clearly visible without a significant shift.…”

At present, dielectric capacitors have revealed large potential in the field of dielectric energy storage thanks to their advantages such as easy processing, flexibility, and long service life. Currently, a variety of methods have been proposed to prepare composite dielectrics with excellent comprehensive performance, which have the characteristics of great insulation strength, good flexibility, excellent efficiency, and large energy storage density. In this research, three composite dielectrics such as BT/PESU, BN/PESU, and TiO2/PESU are prepared by the solution casting method. Herein, we report that the incorporation of low contents of inorganic fillers into a linear polymer leads to concurrent enhancements in both permittivity and breakdown strength. The composite material is conducive to the lightweight nature and miniaturization of dielectric capacitors and at the same time promotes the development of electrical energy storage and conversion devices. The linear dielectric material polyethersulfone (PESU) is selected as the matrix, and it is planned to retain the characteristics of excellent insulation strength and small tanδ of PESU. In addition, by introducing inorganic filler phases with different particle sizes and dielectric constants, the microstructure of the composite material can be adjusted and the macroscopic properties of the composite material can be improved. At last, through comparison, a polymer-based dielectric composite with excellent breakdown strength and energy storage performance was successfully achieved. Fortunately, the discharge energy density of the 1 wt % TiO2/PESU dielectric composite reaches 7 J/cm3 at 570 kV/mm, and its charge–discharge efficiency reaches 87%. This work paves a broad road for the research and development of energy storage materials in the field of dielectric capacitors with high energy storage density, high efficiency, and excellent breakdown strength.

“…3 Organic/inorganic composites are some of the most extensively studied HDMs as they combine the merits of both components, such as enhanced dielectric properties, outstanding thermal stabilities, bio-compatibility, light weight, low cost and remarkable processing properties. [4][5][6][7] Ferroelectric ceramics such as lead-free barium titanate (BaTiO 3 , BTO) have long been of interest as llers for high dielectric composites. 8,9 This is due to their high dielectric constant (as high as 7000), 10 low dissipation, impressive piezoelectric and pyroelectric properties.…”

“…Among these polymers, polyethersulfone (PES) can be regarded as an important kind of special thermoplastic engineering plastics, which has attracted increasing research interests because of its desirable comprehensive properties . To enrich and broaden the application ranges of PES composites, a number of reinforcing fillers including Ba 0.95 Ca 0.05 Ti 0.8 Zr 0.2 O 3 , barium titanate , CaCu 3 Ti 4 O 12 , multiwalled carbon nanotubes , and so on, have been investigated to strength the stability of dielectric properties and simultaneously to promote the increase of thermal decomposition temperatures. In addition to the aforementioned fillers, aluminosilicate fiber (AF) exhibits a lot of distinguishing features, such as high specific strength, strong wear resistance, good thermal stability, and low cost, which makes it as the popular reinforcing fiber in the preparation of thermal insulating materials .…”

In the present work, aluminum phosphate-polyethersulfone (AlPO 4 -PES) laminated composites with three different reinforcement materials, including aluminosilicate fiber (AF), aluminosilicate fiber paper (AFP), and aluminosilicate fiber fabric (AFF), were successfully fabricated by the means of solution blending method and vacuum hot-pressing forming process. The surface morphologies, interfacial microstructures as well as thermal, mechanical, and dielectric properties of the as-prepared composites were researched. The results indicate that both the thermal stability and mechanical properties of AlPO 4 -PES laminated composites are apparently enhanced by introducing AF, AFP, and AFF into AlPO 4 thermal resistant layer. In contrast with AF/AlPO 4 -PES and AFP/AlPO 4 -PES, the AlPO 4 -PES composite containing 10.0 wt% AFF shows higher flexural and compressive properties (187.4 MPa, 4.98 GPa, and 193.7 MPa), together with better thermal insulation performance (0.21 W/[mÁK]). Of all PES-matrix laminated composites, the AFF/AlPO 4 -PES composite also exhibits the outstanding dielectric properties (ε = 1.96, tanδ = 0.008) at high frequency of 5 MHz. Besides, the 10.0 wt% AFF/AlPO 4 -PES composite not only owns the weak frequency dependence of dielectric constant and dielectric loss within the range of 10 2 H to 5 MHz but also exhibits favorable temperature stability of dielectric properties over a wide temperature scope of 25-120 C. This can be ascribed to the excellent dielectric performances of AFF as well as the good interface bonding property of AFF/AlPO 4 layer and PES matrix. POLYM. COMPOS., 40:4102-4112, 2019.
